Chairmanrsquo s Message

Dear SPE Color and Appearance Division Members

Time seems to be accelerating as we race to the end of summer The days aregetting shorter and I wonder if I can sneak in a trip to the beach or short vaca-tion before it is over Very soon it will be time for CAD RETECreg 2014 in NewOrleans The CAD RETECreg 2014 conference chair Earl Balthazar and hiscommittee are working on the final details to make sure the conference meetsthe needs and expectations of CAD members

Past CAD RETECreg typically started with Bob Charvatrsquos seminar on Coloringof Plastics This year was to be Bobrsquos final seminar however his passing earlier this year surprisedand saddened many in the plastic community We will have a small memorial set up for Bob

Charvat so that messages and memories can beshared with fellow CAD members The boardhas decided not to hold the color seminar thisyear in memory of Bob

While in New Orleans you will see many of thesame activities as previous CAD RETECreg The2014 CAD RETECreg Golf Outing will be heldSunday 14th September at TPC Louisianawhich serves as the home of PGA TOURrsquoSZurich Classic of New Orleans Golf enthusi-asts will find the golf outing an enjoyable expe-rience Those looking for a more physical chal-lenge and the opportunity to help the local com-munity can participate in the 5K Fun RunWalkat 7 am on Tuesday 16 September The pro-ceeds from the 5K Fun RunWalk will be donat-ed to the local chapter of Habitat to HumanitySince 2005 SPE CAD has donated more than$25000 Habitat to Humanity Both the golf out-ing and 5K require registration prior to the cor-responding event Refer to the website(specadorg) for more details Those who prefermore social activities will be pleased that theWelcome and Network Receptions will be heldon Sunday and Monday nights respectively

Thanks to the highly favorable response thepanel discussion and New

Editorrsquo s Note

Welcome to the Summer 2014 Editionof the CAD newsletter This editionshould be hitting your mailboxes just

before the CAD RETECreg which marksthe first time since 1991 the conference has

returned to New Orleans Louisiana Of course most of youwill remember that Hurricane Katrina derailed our plans tovisit the Crescent City back in 2005 and so I for one amreally looking forward to this yearrsquos program

This edition of the newsletter also marks my very first offi-cial action as a member of the CAD BOD which I am veryexcited about Having been in this industry since 1989 andnot knowing color from floor sweepings when I started(and maybe I still donrsquot depending on who you ask) thisis a great opportunity for me to try and give somethingback to an industry thatrsquos helped me pay my bills all theseyears I hope to see you all in The Big Easy next month

High Performance Pigments for Demanding Applications Rotational MoldingJoseph J Fay PhD amp Peter Zillitto

Plastics Technical Center Pigments DivisionCiba Specialty Chemicals Corporation

Technical Article

INTRODUCTIONColorants for polymer applications are typically incorporated into the polymer by one of several common pathways Colorconcentrates which are widely used in industry enable the end user to conveniently meter in the colorant at the prescribedration with virgin or uncolored polymer in the manufacturing process The benefits of concentrate used as compared to thedirect use of powder pigment during final product conversion processes include predispersion of the pigment in a suit-able carrier system elimination of the need to in-house compounding to incorporate the colorant uniformly and improvedhousekeeping etc Furthermore color concentrates are available ina number of product forms including pelleted concen-trates liquid color systems and pastes the latter used especially for PVC For polymer conversion processes in which anextruder or meld mixing devise is employed these colorant preparations can be used very effectively In some marketswhere high levels of functional fillers modifiers or polymer blends are used compounders may manufacture ldquoprecoloredrdquopolymer by direct addition of the colorant to their compounding line In come cases concentrates are used depending uponspecific product and process capabilities

Rotational molding in contrast is a low shear process in which traditional pellet form color concentrates are not suitableColoration of rotomolding resin is commonly obtained by the use of dry color and liquid color which can be added direct-ly to the ground rotomolding resin Alternatively precolored resin in which the pigment is compounded into to the poly-mer and then ground before use finds applications as well More recently micropellet technology has been advanced as an alternative to the aforementioned methods It is similar to precompounded color but the need for grinding the polymerinto the appropriate mesh size is eliminated as the micropellets can be rotomolded without further processing For each ofthese color incorporation methods there are advantages and disadvantages including economic factors (process equipmentand material cost) ease of use housekeeping and overall quality (physical properties and aesthetics) of the resulting part

As a consequence of the myriad applications the palette of pigments for rotational molding appears to be quite extensivesimilar to that which is used in general purpose polyethylene application requirements However due to the specific processconditions involved in preparing the pigment system the temperature profile of the rota-tional molding process and the end use application requirement the gamut of pigments issignificantly reduced

Pigment selection may also be affected by the method by which the pigment is to be deliv-ered Liquid colorant systems work best with pigments that have the potential to be loadedto high weight percentages while maintaining suitable viscosity Pigments used in drycolor require characteristics that impart dispersibility and minimize agglomeration duringboth dry color manufacture and blending with the rotomolding resin

DISPERSIONWhen pigments are manufactured the smallest pigment particles formed are discreet units referred to as primary particlesAs a result of their high surface energy these particles randomly join together to form aggregates and agglomerates thelatter being formed primarily during subsequent filtration a nd drying processes To achieve a speck-free system the pig-ment must be effectively ldquodispersedrdquo so that the individual pigment particles or aggregates are wetted by the polymer anddiscrete pigment particles are not visible to the naked eye Rotomolding pigment systems (liquid color and dry color) needto be prepared in a manner that ensures visible agglomerates are eliminated and that during subsequent mixing with therotomolding resin the colorant system will be easily distributed Furthermore the dispersion of the pigment needs to effec-tively deliver a colorant that will provide a high color strength potential to maximize economic while not adversely affect-ing other properties Figure 1 illustrates the particle size of the typical azoncondensation pigment continued on page 12


The following Technical Article was published in 1998 at The Color And Appearance Conference in September

continued from page 11

Note that the particle size distribution that would beobtained in a polymeric system will be very dependentupon the effectiveness of the final dispersion

HIGH PERFORMANCE PIGMENTSHigh performance pigments HPP can be defined as pig-ments that have either very good to excellent heat or lightstability and more commonly pigments which offer aunique combination of both heat and light stability Theenhanced UV and heat performance attributes of HPPs setthem apart from traditional or classical pigments such asthe lithol rubines (PR 571) lake red C (PR 531) 2B toner(PR 48 types) monoaso yellows such as PY 62 and oth-ers which have only limited heat stability and mostly mar-ginal to poor lightfastness

The major types of high performance pigment chemistriescan be described in a general fashion as indicated in Table 1Some individual pigments within these chemistries mayhave better or worse performance characteristics depend-ing upon the specific product attribute and applicationbeing considered

HEAT STABILITYOrganic pigments are available not only with a wide vari-ety of hues and chroma but also with considerable variationin performance characteristics Rotational molding withits combination of relatively long cycle times high moldsurface temperatures and abundance of oxygen is moredemanding upon the polymer stabilization package andpigmentation in comparison to many other processes As aconsequence many rotomolded product applicationsrequire the use of higher performance pigments to survivethe molding process even though the pigment with regardto final product requirements may be viewed as ldquoover engi-neeredrdquo Classical pigments such as 2B reds (CI PigmentRed 48rsquos) with only limited thermal stability in high tem-perature olefin polymer applications may not be suitablefor even non durable articles as the color stability duringmolding may be insufficient Figure 2 compares the heatstability of a calcium 2B toner with high performance dike-topyrrolo-pyrrole (DPP) and quinacridone (QA)chemistries In masstone applications it is readily apparentthat the 2B toner is quite deficient when compared withthese high heat stability pigments Furthermore as pigment


heat stability is generally related to concentration at lowerconcentrations the 2B toner would become even moreprone to color change In addition to pigment instabilitycolor change during rotational molding may be affected byother factors The stability of the base resin is an importantconsideration The role of the antioxidant package is criti-cal to controlling the initial color and maintaining the phys-ical properties of the rotomolding resin Judicious selectionof a phenolic antioxidant and phosphite processing stabi-lizer package is essential for the base polymer Dependingupon specific circumstances additional antioxidant mightbe added The most effective stabilization is typicallyobtained when the antioxidant is added directly to the resinitself during manufacture or during compounding whenrecolored resin is prepared For specialty applications

where additional antioxidants are needed to attain the req-uisite performance precolored or preformulated resinwhich is then ground provides additional benefit

LIGHT STABILITYMany applications of rotationally molded articles find enduses which require UV durability These UV performanceapplications encompass a broad variety of applications andmarkets residential waste containers childrenrsquos play-ground toys (both for residential and institutional uses)outdoor sporting goods (kayaks and component of otherrecreational vehicles) and oversize containers (industrialcontainers and agricultural tanks) For outdoor applica-tions careful formulation is required to achieve not onlysuitable color match but also a color combination whichwill have the desired weatherability As delineated inFigure 3 Calcium 2B toners have limited light stability inpolyolefin applications and are not recommended for usewhere any significant UV exposure is intended Althoughnot reflected in the colorimetric data the 2B toner samplesurface was significantly marred by chalking and surfacemicrocracking and is visible via low magnification optical

microscopy Such microcracks may ultimately result inpremature physical failures of the product Therefore visu-al inspection of samples following accelerated or real-timeexposure testing is imperative to ensure complete perform-ance analysis As a consequence of the limited weather-ability of many pigments performance assessment is need-ed Applications such as point of sale displays and relateditems and indoor applications where incidental UV expo-sure from lighting fixtures or nearby windows is possibleare best formulated with durable HPP pigments Outdoorapplications require the use of HPP pigments at levels thatcan provide sufficient levels of weather resistance

Figure 5 illustratesthe difference inlong-term UV sta-bility that wasobtained when aDPP red (PR254) was com-pared with a pery-lene red (PR178) Perylenepigments areprone to darken-ing when used inconjunction withhindered amine light stabilizers (HALS) whereas no suchnegative interaction has been observed for DPPchemistries

Other high performance pigment classes such as copperphthalocyanine blue pigments may also be suitable foroutdoor applications when properly formulated PB 151and PB 153 are widely used in rotational molding appli-cations as a consequence of their outstanding performanceproperties Figure 6 and tremendous value in use

Inorganic and heavy metal pigments are also widely usedin some rotational molding applications due to their general-ly good dispersibility characteristics and in many cases thecleanliness of shade that may be obtained when using cer-tain cadmium and lead chromate pigments However aswill be discussed in greater detail regulatory pressureshave resulted in heavy metal deselection in several appli-

cation areas including food packaging and many toy appli-cations There applications however have not always beeneasily reformulated The use of HPP products providesalternatives in many color space applications Additionallywith the recent introduction of several new DPP productsPR 264 (Figure 7) PR 272 and PO 71 and PO 73(Figure 8) into the polyolefin and PVC market areas agreater breadth of high performance organics is availablefor formulating In some case differences in the perform-ance of organic versus heavy metal pigments may result inadditional raw material costs Material selection and mod-ification of base stabilization are required in some casesand additional light stabilization packages are needed

continued on page 14




especially when formulating polyolefins for outdoor appli-cations to provide comparable alternatives Nonethelessconsumers (materials specifiers manufacturers and theultimate product purchaser) choosing to avoid use of cad-mium and lead pigments wherever reasonably possibleremains a continuously evolving trend

The formulation of rotationally molded articles for outdoorapplications requires the use of both suitable pigments aswell as the assistance of a well-designed light stabilizerpackage The use of tetramethyl piperidine based hinderedamine light stabilizers especially oligomeric and highmolecular weight types in combination with benzotriazolebased UV absorbers are recommended for use in a varietyof applications The total package loading should be tai-lored to meet the specified requirement of the application

DISTORTION EFFECTSDistortion of rotomolded articles can be effected by sever-al different variables Resin choice and the particular mate-rial being used can affect warpage and shrinkageDifferences in cooling of the mold thickness variationsovercuring and several other process parameters have beenfound to be related to warping Since pigments (and thesystems used to deliver them) may alter the flow character-istics of the polymer and also the cure characteristics oper-ation of a given mold with different pigments or colorantsystems with a single cure cycle may result in differencesin dimensional stability The use of controlled heating andcooling as well as good control over the process itself willhelp to ensure consistent part manufacturing as well as agood data and record keeping can be referred to in case oferratic part quality

IMPACT PROPERTIESImpact properties are commonly tested as a means ofassessing the quality and suitability of colorant systems aswell as for assessing the cure characteristics of the polymerand the properties of the final product The ARM(Association of Rotational Molders) impact test is a com-mon test that is used Alternative instrumented testing pro-vides similar test result capabilities with the advantage ofquantitative and qualitative data acquisition

Impact properties of rotomolded products are importantMany toys containers and other applications require assur-ances of product integrity which can often be affected notonly by the process conditions but also by the incorpora-tion of pigments and other additives Since there is very lit-tle shear in the rotomolding process pigments are likely tobe located at the grain boundary between adjacent polymergranules This localization of pigment and ldquoadditivesrdquo can adversely affect physical properties in sev-eral ways Inhibition of polymer chain entanglementsbetween particles due to additives that form an interfacebetween resin particles can result in weak distinct bound-aries with poor mechanical properties Also pigmentagglomerates which are not broken apart or more trou-bling when they are formed during premixing processesdue to excessive mixing may introduce point defectseffecting physical properties Aesthetic properties may alsobe impacted if agglomerates are present in either signifi-cant size or number Pigment loading which is related toboth the effectiveness in which the pigment can be dis-persed as well as the color requirements of the part isanother factor to be considered in assessing the potentialeffect of coloration on physical properties

REGULATORY ASPECTSWith the variety of applications encountered in rotationalmolding well-publicized legislation and public opinionhave compelled many plastics processors and end-users touse alternatives to cadmium and lead based pigmentsCONEG (COalition of NorthEast Governors) related legis-lation prohibits the sale of packaging materials to whichcadmium lead mercury and hexavalent chromium or theircompounds have been intentionally added Reducing theamount of these elements entering the food chain via wastedisposal sources and the extra precautions needed to dis-pose of post industrial wastes are issues to be addressesCertainly both lead and cadmium-based pigments possessa combination of desireable technical properties that makesthem articularly useful coloring materials for polymersLead based pigments furthermore are particularly eco-nomical in use Nonetheless public opinion and legislationhave had and will likely continue to have a significantimpact on their use particularly in consumer goods

Colorants for polymers that are suitable for food contactuse according to 21 CFR1783297 by the FDA (Food andDrug Administration) NSF (National SanitationFoundation) listing for Potable water contact applicationsand ASTM toy specifications may further place limitationson which pigments may be used

CONCLUSIONSRotational molding presents specific performance require-ment for colorants due to the process dynamics and end-user application needs High performance organic pig-ments in addition to inorganic pigments provide usefulsolutions for designers and manufacturers of rotationallymolded products However as this market continues togrow due to the many unique product features attributed tothe rotomolding process advancements in pigmentationstabilization resin processes and ancillary products shouldalso grow as well Active research and development in sta-bilization technology continues to advance new productsand uniquely designed chemistries (such as lactone andhydroxylamine process stabilizers) into the market placeNew pigment products such as those based upon DPPchemistry also show promise in rotational molding appli-cations Moreover these new products further broadenproduct development potential by providing ever increas-ing performance and greater value in use

Editorrsquo s Note

Welcome to the Summer 2014 Editionof the CAD newsletter This editionshould be hitting your mailboxes just

before the CAD RETECreg which marksthe first time since 1991 the conference has

returned to New Orleans Louisiana Of course most of youwill remember that Hurricane Katrina derailed our plans tovisit the Crescent City back in 2005 and so I for one amreally looking forward to this yearrsquos program

This edition of the newsletter also marks my very first offi-cial action as a member of the CAD BOD which I am veryexcited about Having been in this industry since 1989 andnot knowing color from floor sweepings when I started(and maybe I still donrsquot depending on who you ask) thisis a great opportunity for me to try and give somethingback to an industry thatrsquos helped me pay my bills all theseyears I hope to see you all in The Big Easy next month
