Polymer Processing Aids

An additive added to attain improvement for processing of polyolefin resin at very low levels usage(100~100ppm). It is a white powder made of modified fluoro-elastomer. polymer processing aid is coated at the inside of the die wall and decreases the friction between melted resin and the die wall.



  • Eliminate melt fracture and die-build up
  • Reduce die pressure and extrusion temperature
  • Increase output

Application example
