• Reduce costs, improve surface appearance and reduce warpage compared to glass fiber
.
2014-04-09 Plastics Overview 32
• Excellent color retention and surface appearance - compounding conditions
• All coated products eliminated or reduced dust during feeding
• Extruder torque rates (throughput) increased at equal loading levels by 20%
• Increased throughput demonstrates potential to reduce compounding cost
• Powder grades can be processed and compounded same conditions as talc
• High Aspect Grades – NYGLOS® and ASPECT® – downstream feeding
• Recyclable - Pelletized material fed into main feed exhibited 98% retention
• Tailored modification to further enhance processing, properties and reduce dusting
