Introduction

Lexan* XHR6000 is a new opaque aircraft grade sheet which offers robust OSU

65/65, smoke, flame, and toxicity compliance along with the advantages of

lower weight, lower processing temperatures, improved ductility and improved

colorability versus current OSU and FST compliant sheet grades.

Full compliance to FST and OSU, eliminates the need for waivers and other time

consuming product approvals.

With a specific gravity of 1.34, Lexan XHR6000 can provide critical weight savings

where every kg of weight taken from an airplane results in approximately $2000

in fuel savings per year.

Lower processing temperatures compared to Ultem* or Polyphenylsulfone

(PPSU) sheet means lower cost tooling, lower heating costs, faster cycle times,

and lower part costs. In addition, Lexan XHR6000 provides increased design

freedom because it forms similar to standard Lexan sheet products. It is capable

of deep draws, crisp angles and thin walls.

This product is an excellent choice for seating components, fuselage cladding,

window shades, door shrouds, window surrounds, cockpit linings and trolleys.

Thermoforming XHR60000

Thermoforming is an established process that offers the designer the freedom to develop complex shapes and forms with cost/performance characteristics that have significant advantages over more traditional methods of production. Low cost tooling, large part production, and reduced lead times all contribute to the advantages of producing sheet products in this way.

Thermoforming requires heating the plastic sheet to its softening temperature and drawing the soft material over or into a mold using vacuum or air pressure. When the part has assumed the shape of the mold, it is allowed to cool, and is then removed from the mold. The use of heated positive air allows much higher pressures, making sharper detail possible.

Lexan XHR6000 sheet is easily thermoformed with sharp detail on any conventional forming equipment capable of quickly transferring the sheet from the heating station to the mold or forming table. Rapid transfer is necessary because the sheet cools quickly and becomes form-stable at a higher temperature than other materials. Although double-oven automatic or semi-automatic forming equipment is recommended for Lexan sheet, single-sided heating canopy-type equipment can be used. Avoid using separate heating and forming devices, such as are often used to form acrylic.


DryingAlways dry Lexan XHR6000 sheet prior to vacuum forming.Small amounts of moisture absorbed in storage or shipment can cause moisture bubbles, loss of forming detail and visually unattractive surfaces.

For drying, use a vented, air circulating oven at 250°F (121°C). Place the sheets vertically in the oven, or in racks that provide a minimum separation of 1 inch (2.5 cm) between sheets. When a sheet has been dried, it may be used for up to 12 hours without re-drying depending on environmental conditions. When using automatic equipment, cool the sheet to room temperature to maintain uniform cycles. Remove any protective masking before predrying.

Drying Recommendations for Lexan XHR6000General Rule of Thumb: 2 minutes per mil (25 micron)Example: 0.122 inch (3 mm) requires 4 Hours of drying at 250°F (121°C)

Clamping FramesPlace the pre-dried sheet in machine clamping frames capable of exerting sufficient force to prevent the sheet from pulling out during forming. The frame should also provide some stripping action as the formed part is removed from the tool. The mass of the metal clamp frames can cause a substantial difference in sheet temperature between the relatively cool edges of the sheet and the heated center. Therefore, design clamping frames to allow maximum temperature build-up in the sheet under the clamp.

Always preheat the clamp frame to 250°F (121°C) and maintain them at this temperature. It is common to paint clamp frames black to maximize radiant heating of the frames. If small individually controlled heating el-ements are not available, shading is sometimes used on the center portion of the sheet to allow faster heating of the clamp and sheet edges. Heaters may also be put into the clamps themselves.

Allow 1/2” to 1-1/4” (13 – 32 mm) between the clamp frame and the mold vacuum box to permit a positive seal.

Forming Temperature To preserve the fine texture on the Lexan XHR6000 sheet, keep the sheet surface temperature on the textured side below 390°F (200°C). Heated forming tool temperatures should be maintained between 230 –255°F (110 – 124°C).

Heating/Cooling CycleWhen Lexan XHR6000 sheet reaches forming temperature, bring it down over the tooling and apply vacuum. Lexan sheet sets up very quickly, permitting a much shorter cycle than is possible with most other materials. Remove the formed part from the mold as soon as the material is form-stable and still hot to the touch. Avoid stress build-up and difficult removal due to post mold shrinkage by removing the part from the tool when the part temperature reaches 250°F (121°C).If possible, perform the trimming operation while the part is still warm to minimize flange warpage.

Texture Retention During FormingTo preserve the fine texture on the Lexan XHR6000 sheet, keep the sheet surface temperature on the textured side below 390°F (200°C). Also, during the forming process, profiling the vacuum forming ovens can be beneficial. The heaters that directly impinge on the textured surface should be set to a lower output than the bottom side ovens. EXAMPLE: top heater output set at 25% bottom heaters to 77 or 75% will be a good starting point. If these settings increase the forming cycle time to an unacceptable level, try increasing the bottom heaters to 90% or higher.


Shading or ScreeningShading, a technique used to balance out hot spots in an oven for temperature uniformity, can also be used to control the sag of Lexan XHR6000 sheet when heated. In addition to preheating the metal clamp, cold edges and corners can be overcome by using ordinary metal window screening to shade all of the sheet except several inches along the edges.

The window screen can be positioned on a support rack between the heaters and the Lexan XHR6000 sheet. The number of layers and position of the screen depends on the desired location and shape of the sag. When using shading, heat slowly. This is especially important with heavier gauges of sheet to prevent gradient heating and to provide more opportunity for heat to be conducted to the center of the sheet. Reduce the heating rate by using a lower intensity or by moving the sheet away from the heaters.

4. Sag and Tool Placement

5. Screening or Shading During Forming

Controlling Sagging As the Lexan XHR6000 sheet approaches forming temperature, it will begin to sag. The edges and corners of the sheet along the metal clamp frames must be softened sufficiently to provide a vacuum seal when the sheet is pulled over the vacuum box and mold. The sag is predictable, and is a reliable method of determining the heating cycle.

Uniform sag and consistent forming cycles are necessary for good part detail and proper registration of pre-decorated parts. To determine sag automatically, install an “electric eye” on the equipment. Determine the proper sag using a manual cycle, then set the electric eye to trip the forming sequence thereafter.

Another reliable method for consistent part-to-part forming is to use an IR sensor to trigger the cycle at a given sheet surface temperature.

A final satisfactory but less accurate method of controlling total heat input is to control the heating time. During production runs, electrical power fluctuations can cause variations in heat output. Air drafts, which affect the rate of heat absorption or oven temperature build-up, can also cause changes in the heating rate of the sheet. Since variation is often small, this type of heating control can be used for regulating sheet temperature. However, for the most critical type forming (prescreened sheets), more precise control, such as electric eye drape control or triggering off of sheet temperature, may be required.

Mold MaterialsInternally heated cast or machined aluminum molds have been successfully used with Lexan XHR6000 and are suggested for long production runs and parts that require fine, small areas of definition. Small production runs and prototype parts can be produced using woods, epoxy, silicone, and other similar materials allowing for inexpensive prototyping and tooling modifications if part changes are necessary.

ShrinkageAllow for 0.7 to 0.9% of part dimension for mold shrinkage.

Draw RatioLexan XHR6000 is capable of a 3 to 1 draw ratio (300%). That is the height of draw can be three times the width of the part or the ratio of the original sheet thickness to the stretched sheet thickness can be 3/1.

Draft AnglesUse large draft angles of 5° - 7° when part geometry allows. Minimum draft angles should be two to three degrees on a male mold and one half to one degree on a female mold. Molds with textured surfaces may needmore draft so the part will release without scratching. Approximately one degree per mil (25 micron) of texture depth is usually sufficient.

Radii and FilletsRadii on ribs and fillets should not be less than theminimum part thickness. The radii should be as muchas four to ten times the wall thickness in areas of highloading or where extra stiffness is required. Radii should increase as part depth increases.

Undercuts Generally, undercuts should be avoided. However, if they are necessary, removable inserts or cam-actionmold parts should be used.


Vacuum holesVacuum holes should be drilled in all areas that require detail. These vacuum evacuation holes should be kept as small as possible to minimize dimple formation of the finished part. Vacuum holes with diameters less that 0.030 inch (0.750 mm) should minimize dimple mark-off. Back drilling with larger holes will produce a more rapid air evacuation and make drilling the small surface holes easier.

Molds can also be made with long slots instead of holes to remove air. Slots are most commonly used in female tooling with a loose bottom insert or for perimeter vacuum on male tools. Slot gaps should be 0.030 inch (0.75mm).

Mold Surface FinishSince the part detail is better on the side of the material that contacts the mold, female molds are used when exterior part details are required, and male molds should be used when the interior of the part requires detail. Male molds may also be preferred when the exterior surface details are minimal and the exterior polish or matte finish of the sheet needs to be preserved. Large flat mold surfaces should not be highly polished because they will restrict the flow of vacuum and can cause air entrapment. Slightly sand the mold surfaces in the direction of draw to insure proper vacuum evacuation (600 grit paper is recommended).

Plug AssistsPlug assists pre-stretch the sheet and assist in forming. Plugs are designed to conform to the cavity. Compared to the cavity, plugs should be 10 percent to 20 percent smaller in length and width to allow for clearance between the sheet and the mold. Moreover, the plug should have no sharp corners.

Thermoforming TroubleshooterBlue Spots• Spots form due to the combination of TiO2 in the

formulation of white colored sheets combined with the presence of organic fiber such as polyester fibers from clothes at elevated temperatures.

Reason:• TiO2 is a heat conductor facilitating organic fiber

decomposition• Trace amount of organic fiber impurities are not

detected by conventional analytical techniques

Recommendations for Minimizing Spots:• Clean surface thoroughly before forming• Minimize forming temperatures if possible

Table 2: Troubleshooting tips


The following section discusses the techniques and processes used to fabricate finished products from Lexan XHR6000 sheet and provides recommendations and advice on how to achieve the best results

Bonding and FasteningThe table at the bottom of this page lists several adhesives and shows their bond strength as well as their chemical compatibility with Lexan XHR6000. Of the products tested, 3M Scotch Weld and IPS Weld-On 55 1 provided acceptable results. Adhesive thickness is critical to producing acceptable bonds and the adhesive supplier should be consulted for the optimum thickness to use.

CuttingLexan XHR6000 sheet can be cut with a variety of common hand-held and table mounted sawing equipment. Remember, take care to protect yourself from injury. Use appropriate eye and ear protection and exercise caution when operating cutting equipment.

Special attention to blade design and cutting speed is important to obtain good quality finishes.

Circular SawsThe blade should be designed to minimize blade body rubbing during sawing. Fine tooth hollow ground blades and triple chip carbides are excellent choices and will produce a good quality surface finish.

• Thin gauge sheet: 1/16”–3/32” (1.6 – 2.4 mm) – Hollow ground panel blades. – 10-12 teeth per inch (25 mm).

• Heavy gauge sheet: 1/8”–1/2” (3.2 – 12.7 mm) – Triple chip cut carbide blades with alternating

bevel and straight teeth. – 3 teeth per inch (25 mm).

Band SawsLexan XHR6000 sheet can be cut in all thicknesses satisfactorily with band saws.• 10–18 teeth per inch (25 mm).• Blade speeds: 2500–3000 feet per minute

(762 – 914 m/min).

Milling and RoutingHigh rotating speeds or low feed rates are advisable for end milling. Higher feed rates are permissible, but only with increased milling speeds.

The use of right or left handed spiral cutting bits with handheld or table mounted routers will minimize material chatter and help hold the Lexan XHR6000 sheet against the router surface.

Bit Recommendations• Spiral router bits are preferred.• Two- or three-fluted carbide tipped bits, 3/8”–1/2”

(10 – 12.7 mm) diameter, can also be used.

Router Speeds• No-load speeds: 25,000–30,000 rpm.

DrillingLexan XHR6000 sheet can be drilled easily using a standard twist drill design. High speed steel or carbide tipped twist drills will give the best results with the following conditions.

Hole Diameter

Speed(rpm)

Feedmils./rev. (mm/rev.)

Time(sec.)

1/8 (3.2 mm) 1750 1.5 – 3 (0.04 – 0.07) 25–30

1/4 (6.4 mm) 1000–1500 1.5 – 3 (0.04 – 0.07) 30

3/8 (9.6 mm) 500–1000 1.5 – 3 (0.04 – 0.07) 30

1/2 (12.7 mm) 325–650 3 (0.07) 45–50

3/4 (19.2 mm) 350 3 (0.07) 50–60

• To minimize the drill’s tendency to pull into the material, modify the standard steel twist design by grinding a small flat on the cutting edge.

NOTE: Do not use drills that have been ground for use on acrylic sheet. They will overheat the material, and induce unwanted stresses.

Shearing, Punching, and BlankingPunching and shearing are effective methods for cutting Lexan XHR6000 sheet into workable sizes. However, the sheared edge should be removed by a secondary routing operation to minimize high stress areas.

Compared to acrylic, which will shatter, Lexan XHR6000 sheet will not crack or craze during shearing, punching or blanking when sharp tools are used.

ShearingSmooth cuts can be obtained by shearing with the following guidelines:• Shear blades: 45° angle or less• Maintain 0.0005”–0.001” (0.0127 – 0.025 mm)

clearance between blade and shear bed.

PunchingHollow ground punches can be successfully used, but it may be necessary to make provision for hole shrinkage if hole diameter tolerance is critical.

Punching Example:

Hole Diameter Sheet Thickness Typical Shrinkage

1/2” (12.7 mm) 1/8” (3.2 mm) .007” (0.175 mm)

1/4” (6.4 mm) 1/8” (3.2 mm) .004” (0.1 mm)

BlankingThe ductility of Lexan XHR6000 sheet allows for blanking with clean edges, unlike acrylic which is far more brittle.• Conventional steel rules and clicker dies provide

excellent results.• Sharp tools yield best edges.
