K 2013: 19th International Trade Fair for Plastics and Rubber WACKER Presents All-Purpose Silicone Additive for Food Contact Plastics

Munich, October 1, 2013 – At the International Trad e Fair for

Plastics and Rubber K 2013, the Munich-based chemic al group

WACKER will present a high-performance additive for the

compounding and processing of thermoplastics. GENIO PLAST®

Pellet P plus improves the viscosity and flow prope rties of the

polymer compound, allowing the compound to be proce ssed

more efficiently and at lower cost. It also ensures smooth, easy-

to-clean surfaces. GENIOPLAST ® Pellet P plus is an approved

additive for plastics used in food contact applicat ions and is

therefore suitable for plastics in the kitchen and packaging

sector. This year’s K 2013 will take place in Düsse ldorf,

Germany, from October 16 to 23.

GENIOPLAST® Pellet P plus is a highly concentrated silicone additive

in pellet form. Its active ingredient is a non-crosslinked ultra-high-

molecular linear silicone polymer, while the carrier material for the

active is a pyrogenic silica tailored for the silicone. Since pyrogenic

silica is compatible with all thermoplastics, the additive can be used to

compound every type of thermoplastic – unlike conventional silicone

masterbatches. It is therefore no longer necessary to stock a range of

masterbatches to suit each different thermoplastic compound.

GENIOPLAST® additives give thermoplastic compounds smooth,

scratch-resistant surfaces, without impairing tensile strength,

hardness or dimensional stability under heat. Printing and welding of

the compound is still feasible. In mineral-filled thermoplastics, adding

GENIOPLAST® also boosts impact strength and elongation at break.

Additionally, the product can act in synergy with flame-retardant

fillers.

Unlike GENIOPLAST® Pellet S, which is used in compounds for

technical applications, such as in car interiors or for cable sheathing,

GENIOPLAST® Pellet P plus is designed specifically for compounds

in food contact applications. Thanks to the smooth surface achieved

by the additive, it is particularly easy, for example, to clean and empty

refrigerator inserts made of acrylonitrile-butadiene-styrene copolymer

(ABS) and food packaging based on polypropylene compounds (PP).

With the silicone additive, it is also easier to remove plastic corks

from wine bottles.

GENIOPLAST® Pellet P plus is simple to meter and is readily

incorporated into thermoplastics, including those with mineral fillers.

The active silicone ingredient improves filler dispersion when

producing the compound and also its melt flow, which makes it easier

for processors to shape the thermoplastic. Thus, GENIOPLAST®

Pellet P plus is an effective processing aid for compounders. It cuts

energy consumption, increases throughput and reduces waste,

opening up cost-saving potential.

In addition, GENIOPLAST® Pellet P plus facilitates the production of

injection-molded parts. Processors are able to improve mold filling

and inject more material into the mold per unit time. As a result, they

can reduce cycle times. Demolding of the parts is also easier. Thus,

GENIOPLAST® lowers the unit costs for producing molded parts.

Moreover, if compounds are processed by extrusion rather than

injection molding – e.g. to make cable sheaths – the additive also

enhances processes and lowers costs.

With its silicone content of about 70 weight percent, GENIOPLAST®

Pellet P exceeds that of masterbatches. This makes the additive very

efficient: as little as between 0.1 and 1 weight percent is already

sufficient to obtain process-enhancing properties. Improved plastic

properties can be achieved with quantities of 1 to 5 weight percent.
