⚠️ Processing Advice

The material is supplied in airtight bags, ready for use. If the virgin material has absorbed moisture, it must be dried with dehumidified air drying equipment (dew point minimum -20°C). Recommended drying time: 2-4 hours.

For extrusion applications, use a screw design specifically for very high viscosity grades to ensure stable melt pressure and good profile dimensional stability.

🎯 Target Applications

📐 Profile Extrusion
Window insulation profiles, industrial profiles
🔧 Tubing
Pneumatic tubing, hydraulic tubing
🏭 Industrial Components
Wear parts, structural parts
⚽ Consumer & Sports Goods
Ski bindings, sports equipment
