Polymer Processing Additive（PPA-5920HV）
PPA-5920(HV) is a kind of free flow white powder fluoropolymer based processing additives. At a very low level addition(400-1000ppm), it can improve PE processing and does not affect the original physical property of the plastics as well as sealing, adhesion and printing, can be used for mLLDPE, LLDPE, HDPE, LDPE, EVA and other polyolefin resin.

Processing Guide :
The dispersion of PPA in resin determines the performance. The recommended process is to add PPA via 3%-5% Masterbatchthrough twin-screw extruder, and then add it into the extrusive resin according to the ultimate goal. The conditioning time is 10-60 minutes according to the equipment, base material and shear rate. No conditioning time when long-term use of this product.
