Applications
  • Chemical coupling agent for fillers like mica talc, calcium carbonate, wood flour in PP compound.
  • Coupling agent for glass fibers in PP compounds.
  • Compatibilizers for blends such as PP/PA and PP/EVOH.
Processing Conditions
  • A slight pungent odor is normal during processing of OPTIM® P-445.
  • During processing, the compounding parameters that can lead to optimized performance include extruder type, screw design, barrel temperature, screw speed, throughput, residence time and material feeding sequence.
  • Maximum processing temperature should not generally exceed 280 °C.

Packaging Information
  • OPTIM® speciality polymers are supplied in pre-dried form in 25 Kg (55 lbs) PE lined, HD woven sack-laminated paper bags and 750 Kg (1650 lbs) FIBC’s.
  • They should be stored in cool and dry place.

Storage & Handling

Storage and Handling Procedures
  • OPTIM® P-445 is mildly hygroscopic and should be stored in a dry and cool area.
  • It is recommended that prior to processing, the requisite quantity of material to be used should be dried in a hopper dryer or oven at 80-95°C for about 2 hours for obtaining best results.
  • Loss of anhydride functionality may occur due to conversion to acid groups by reaction with atmospheric moisture.
