Product Description

PVC Processing Internal Lubricant For PVC Plastic Auxiliary Agents


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).


Internal lubrication

As for the internal lubrication of lubricant, as far as PVC is concerned, it can be regarded as the same kind of material as plasticizer, which plays a role of plasticization or softening. The difference is that the lubricant has a lower polarity and a longer carbon chain. Therefore, compared with plasticizers, the compatibility of lubricants and polyvinyl chloride is significantly reduced. It is precisely because of the low compatibility of lubricants and polyvinyl chloride ( And there is a certain compatibility), so only a small amount of lubricant molecules can penetrate between the molecular chains of the polymer like plasticizers, weakening the mutual attraction between the molecular chains, and when the polymer is deformed, the molecular chains It is easier to slide and rotate with each other, while not excessively lowering the glass transition temperature of the polymer.

What happens if the PVC lubricant is not used well?

The role of PVC lubricants in PVC processing is no less than that of stabilizers. Its use generally needs to follow strict principles, such as internal and external slip balance, moderate amount, etc.


Unbalanced internal and external lubrication.

Too much external slippage, although the extrusion speed is fast, but the material is easy to produce, poor plasticization; too much internal slippage, large extrusion volume, the material plasticization is not good. If the initial lubrication is not good, the extrusion torque will be too large. Insufficient lubrication in the later period will lead to insufficient lubrication in the screw homogenization section, compression section, and die section, and the material shears violently, which will affect the surface quality and internal performance of the extruded product.
