About Internal Lubricants
The internal lubricants main function is to reduce the frictional forces of the PVC molecular chain, reduce the viscosity, improve the flow properties and final product quality without adversely affecting the material bulk properties. This helps in reducing the mechanical torque of the extruder at gelation and improves the compatibility with resin.
FAQs
What are Internal Lubricants?
Internal lubricants are additives used in PVC and plastic processing to reduce friction between polymer molecules during melting and mixing.
Why are Internal Lubricants used?
They help:
- Improve melt flow
- Support faster fusion
- Enhance processing efficiency
- Maintain product strength
Where are Internal Lubricants used?
They are commonly used in:
- PVC pipes and fittings
- Profiles and sheets
- Injection molded products
- Extruded plastic products
Do Internal Lubricants affect product quality?
No. When used correctly, they improve processing without reducing mechanical strength or durability.
What are the benefits of Internal Lubricants?
- Better dispersion of additives
- Improved surface finish
