Applications
  • Impact modifier for full range of filled and unfilled PC, PET & PBT. Level of improvement obtained is a function of the OPTIM® GE-344 addition level.
  • Scrap upgradation of PC, PBT and PC/PBT blends.
  • Chemical coupling agent for mineral and glass fillers in PET & PBT compounds.
  • Useful for low temperature applications.
Processing Conditions
  • OPTIM® GE-344 can be added to polycarbonates & polyesters to achieve good dispersion of fillers within the polymer matrix thereby obtaining best properties.
  • It is recommended to purge the equipment thoroughly after a run is completed as OPTIM® GE-344 tends to crosslinks when kept for long periods at high temperatures.
  • Maximum processing temperature should not generally exceed 290°C.
