Polymer Processing Aid

Product Features:

Rheopoly® PPA3520 is free flow, 25mesh 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 resins.

Product Form:

White to off-white  granular


Blow film ,Cast flim ,Blow molding and all other  polyolefin extrusion process

Physical properties:

Bulk Density


Particle Size

25 mesh

Volatile (105 1h)%


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  frature

- Shorten down time 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
