Function of External Lubricants

External lubricants procured from the lubricants manufacturers in India have different functions compared to internal lubricants:

1. Improving Surface Finish: 

External lubricants enhance the surface finish of PVC products, giving them a smooth and glossy appearance. This is particularly important in applications where aesthetics matter, such as PVC pipes or profiles.

2. Enhancing Mold Release: 

In injection moulding, external lubricants act as mould release agents, preventing PVC from sticking to the mould cavity. This facilitates easy demolding and reduces production cycle times.

3. Controlling Coating Thickness: 

External lubricants can be customized to control the thickness of coatings in applications like PVC dip moulding. This ensures consistent and precise coating thickness.

In summary, both internal and external lubricants are essential components in PVC processing, each serving specific functions like reducing friction, enhancing surface finish and preventing sticking.
