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.
White to off-white granular
Blow film ,Cast flim ,Blow molding and all other polyolefin extrusion process
Volatile (105℃ 1h)%
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
