PVC lubricant

PVC lubricant

 

Normally, there two types of lublicant for PVC indutry, internal and external lubricant.

An internal lubricant is with good performance at:

1.Reducing heat in production process;

2.Give lower melt viscosity;

3.Postpone gelation;

4.Improve flow charateristics.

 

While an external lubricant supporting following performance:

1.Delay gelation;

2.Improve gloss;

3.Reduce friction;

4.Provide release properties.

 

For PVC process, Internal lubricants mainly including:

Stearic acid, Calcium stearate, GMS, DMG, n-butyl stearate,

 

As for external lubricants for PVC, these are popularly used:

PE wax,Paraffin wax.

 

Oxidized Polyethylene A-T 316A is a typical external lubricant. As a substitute of Honeywell A-C 316A, it can significantly support plasticization and improve melt strength, and with good de-moulding performance.
