10% Glass Filled PTFE
The glass-in-glass-filled PTFE is available in 5%, 10%, 15%, 20%, and other custom blends. Contact us for more information.
Description
10% glass-filled PTFE is a plastic composite material made from 90% PTFE and 10% glass fibres. The most popular filler for PTFE is glass fibre, which improves the material’s wear, compression and creep resistance. It has excellent electrical properties with a low coefficient of friction and non-stick properties.
The material is available in rod, tube, and sheet forms. Also available in 5%, 10%, 15%, 20%, and other custom blends.
Key Properties
- Very low coefficient of friction.
- Excellent chemical resistance.
- Excellent dielectric properties.
- Resistance to weathering
- Self-Lubricating
Applications
10% glass-filled PTFE offers a reliable and cost-effective solution for applications that require enhanced mechanical performance without compromising chemical compatibility. The material is ideal for seals, gaskets, and structural components across a wide range of industries.
