• Reduce costs, improve surface appearance and reduce warpage compared to glass fiber

.


• 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

PROPERTIES can be

further improved by moving the side

feeder farther downstream.
