Applications
  • Coupling agent for fillers and reinforcements in HDPE like wood plastic composites(WPC’s).
  • Chemical coupling agent for fillers like calcium carbonate, talc, mica & glass fibers in HDPE matrix.
  • Wetting & Dispersing agent for colors and pigments in PE compounds.
Processing Conditions
  • A slight pungent order is normal during processing of OPTIM® E-156.
  • 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.
