Polymer Processing Aids (PPA) 5920

PPA Introduction

Polymer Processing Aids are free-flowing additives made of modified fluoro-elastomer which improve the processing of polyolefin resin at very low levels of usage. BX Polymer Processing Aids are coated at the inside of the die wall and decrease the friction between melted resin and the die wall.

BX PPA 5920 is a free flow, 25 mesh white granular fluoropolymer-based process aid. At a very low-level addition (  200-1200ppm), it can improve PE processing, and does not affect the original physical property of the plastics as well as sealing, adhesion, and printing. It can be used for  mLLDPE, LLDPE, HDPE, LDPE, EVA, and other polyolefin resin


Wire and cable jacket materials, insulating materials, cross-linked pipes, etc.

Processing Guide:

PPA dispersion in the resin is critical to the performance. The recommended process is to add PPA via 2% to 3% masterbatch through twin-screw
extruder. The conditioning time is 20-60mins according to the equipment, resin, and shear rate.


– Improve film surface quality by eliminating melt fracture.
– Shorten downtime by reducing die build-up.

– Increase the ratio of LLDPE in LLDPE/LDPE blends for lower cost, higher quality

– Increase output and energy saving

Shelf life:

2 years, below 30℃, avoid extensive humidity and light


Net 20kg, per carton
