Polymer Processing Aid PPA9022 PPA 9022 is free flow, 25 mesh 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: White or off-white powderApplication: Blow film, Cast film, Blow molding and all other polyolefin extrusion process.[Physical Property ] ITEMUNITVALUEBulk Densitycm30.7gParticle sizemesh25Volatile（105℃1h）%0.15Processing GuideThe 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 PPA9022 long-term continuously.Product Functions Improve film surface quality by eliminating melt fracture;Reduce wears of a mold in the processing; eliminate the die build up;Increase the ratio of LLDPE in LLDPE/LDPE blends for lower cost, higher quality;Increase output and save energy.Shelf Life 1 year, under 30℃, avoid extensive humidity and light.Packing Net 20kg per barrelFood Contact Safety PPA meets the requirements of FDA 21 CFR 177.1520 USA. It can be used in food contact.
