intenal lubricant widely used in the actual processing

Lubricants plastic widely used in the actual processing of plastic, for example kneading, the rolling process, to prevent adhesion of the polymer cartridge suppressing friction and heat, and the load torque decreases kneading, thereby preventing the polymer
material of the heat deterioration. In the  WSD PVC flame retardant extrusion molding, to improve flowability, the polymer material and to improve adhesion
of the barrel and the die, to prevent and reduce retentate. Another film but also to improve the appearance and gloss.
Plastic lubricants can be divided into effect, the two plastic lubricants, intenal lubricant is mainly to improve the frictional
heat the metal surface of the polymer melt and processing equipment. Lubricants plastic outer poor compatibility with the polymer is easy to migrate out from the melt, so the lubrication can be formed in a WSD Processing aid  thin layer of plastic and metal melt interface. Plastic lubricant has good compatibility with the polymer, intenal lubricant which serves to reduce the effect of cohesion between
the polymer molecules within the polymer, thereby improving the plastic melt in the heat of friction and melt flowability. Commonly used lubricants are stearic acid and salts thereof outside; plastic lubricant is a low molecular weight polymer. A plastic lubricant with different polymers under different processing conditions or exhibit different lubrication, such as high temperature,
high pressure, the lubricant will be squeezed out of the inside and outside of the lubricant becomes.
