2.Modified PP Automotive Materials

   By PP and elastomers, rigid particle compound modification, can increase the PP of the low temperature toughness and heat resistance, aging resistance, weather resistance, reduce mold shrinkage, can be widely used in automobile bumpers, steering wheel, instrument panel and interior , heater hood, fenders, front door shield assembly, filter housing and other components.

3.Recommended processing conditions:

Drying temperature :90-100, 2HFeeding section: 200 ~ 210 °C the middle section: 210 ~ 240 °C nozzle section: 210 ~ 230 °CInjection pressure of 50 ~ 90MPaHolding pressure 40 ~ 70 MpaMold temperature 30 ~ 50 °CBack pressure 5 ~ 10 Mpa
