Lubricant for PVC is divided into low temperature lubrication, medium temperature lubrication and high temperature lubrication. Low temperature lubrication plays a role in the early stage of processing, such as paraffin, stearic acid, monoglyceride, butyl stearate, stearol, etc.; medium temperature lubrication plays a role in the middle stage of processing, such as PE wax, ope wax, lead stearate, cadmium stearate, etc.; high temperature lubrication plays a role in the later stage of processing, such as calcium stearate, barium stearate, etc.
Internal Lubricant for PVC is that after melting, lubricant melts into the inner part of PVC melt, which lubricates and reduces friction between molecules in the melt. We call it internal lubricant. The internal sliding agent has the following performance and characteristics in PVC processing and production:It Reduce the friction in the resin after melting.Reduce the viscosity of melt and the expansion of mold. Lower Vicat softening point. Reduce melt fracture.
External Lubricant for PVC is that after the lubricant is melted, a film is formed between the surface of the screw, mould, screw and the surface of the PVC melt, which is called the external lubricant. The external sliding agent has the following performance and characteristics in PVC processing and production,Improve the glossiness of the product surface and prevent the material from adhering to the hot metal surface.Adjust material plasticizing point. The plasticizing point of the material can be delayed and the plasticizing time can be delayed by increasing the external sliding agent.
