Introduction
LANPOLYTM PPA 2800 is free flow, 25 mash white powder fluoropolymer based processing aid. At a very low level addition（50－800ppm), it can improve PE processing without 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.
Product Form

Processing Guide
The dispersion of PPA in the resin determines in a large part the using effect, the recommended process is make the 2% - 3% master batch by the twin-screw extruder, and then add it into the extrusive resin according to ultimate goal. When using for the first time, there are 20-60 minutes onset time according to the equipment, the base material and the shear rate. No onset time for the equipment that use PPA 2800 long-term continuously.
