HY-316 is a newly type compound processing assistant and its main composition are compound polarity and non-polarity, straight chain and branch chain polyolefin and copolymer. It can quicken plasticizing for PVC resin and enhance speed of extruding that can reduce consumption of ACR.AC-316 has an ultra-metal stripping characteristics and meantime become high effective exterior lubricant for PVC processing.AC-316 has a good compatibility with PVC resin in transparent PVC products and it has high efficiency of exterior lubricating that obviously reduced its consumption than compound ester exterior lubricant. Hence, its products with best transparency and downed the prescription cost.
