White Powder External Lubricant For PVC Slight Yellow Flake Or Powder

Lubricants are essential additives in PVC processing. For lubricants, the effects commonly mentioned in the industry can be attributed to two points:

1. Can reduce the friction between the particles before the melting of PVC and the macromolecules in the PVC melt.
2. Reduce the mutual friction between the contact surface of PVC melt and plastic machinery. This is actually the most typical summary of the role of lubricant 2 (internal and external lubrication).

External lubrication

External lubrication refers to the interface lubrication mechanism. The lubricant adheres to the surface of the molten resin or to the surface of the processing machine or mold to form a lubricant molecular layer. The lubricating interface is formed due to the presence of the lubricant molecular layer. As a result, the friction between the resin and the processing machine is reduced. The viscosity of the lubricating interface film and its lubrication efficiency depend on the melting point of the lubricant and the processing temperature. In general, lubricants with long molecular carbon chains can make the two friction surfaces farther away, so they have better lubrication.

Product Advantages:

1. Without any effects on the fusion time.
2. Improve the melt flowability.
3. Without any effects on transparency.
4. Provide lubricating property without lowering melt-strendth.
