External Lubricant

PVC external lubricant is a kind of additive used in PVC processing, the main function is to form a lubricant film between PVC and processing equipment, reduce the direct contact between PVC and equipment, reduce friction and wear, and improve processing performance. Compared with the internal lubricant, our H-74 external lubricant is especially suitable for the processing of soft/hard PVC granules, transparent sheets and shrink films, which has less influence on the melt fluidity of PVC, and also reduces the equilibrium torque and strengthens the demoulding effect.

Benefits of External Lubrianct

1. Reduced friction and wear:

External lubricants can significantly reduce friction between PVC and processing equipment, reducing wear and tear and extending equipment life.

2. Increased Processing Window:

The use of an external lubricant extends the temperature range of PVC processing, allowing for more flexible processing and easier adjustment of processing parameters to meet the needs of different products.

3. Reduced adhesion:

In certain processes, such as extrusion and injection moulding, external lubricants can reduce the adhesion of PVC to the mould, reducing product defects and improving product consistency.
