An additive added to attain improvement for processing of polyolefin, PP, PET,… resin at very low levels usage (100~1000ppm). 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.
