PTFE
PTFE (polytetrafluoroethylene) is a fluoroplastic with exceptional chemical and thermal resistance that exceeds most other plastics. It is resistant to almost all aggressive substances and is also used in the food industry. Thanks to its excellent dry-running properties, it is ideal for seals and guide elements operating with low lubrication and high sliding speeds. The weakness of PTFE is lower abrasion resistance and a tendency to so-called cold flow, which can be reduced by using fillers such as bronze, glass fibers, carbon, or MoS₂.
Not sure which material is right for your application?
Tell us your operating conditions and we will help you choose the right solution:
- Operating medium (oil, water, air, chemicals, etc.)
- Working pressure and temperature
- Whether the seal is used in a dynamic or static application
- Dimensions or a physical sample
Based on this information, we will recommend the most suitable material and design, and prepare a non-binding quotation.
