With over 50 years of dedicated experience in foam conversion, our Kent-based team of engineers and designers offer vast expertise in developing high-quality
Why choose PTFE foam?
Polytetrafluoroethylene (PTFE) foam is renowned for its exceptional chemical resistance, thermal stability, and non-stick properties. Its unique combination of characteristics makes it an ideal material for applications requiring:
-
- Chemical resistance: PTFE foam withstands exposure to a wide range of chemicals, acids, bases, and solvents, ensuring longevity in corrosive environments.
- Thermal stability: operating effectively across a broad temperature range, PTFE foam maintains its integrity in extreme thermal conditions
- Non-stick surface: the low coefficient of friction prevents adhesion, making it suitable for applications where cleanliness and ease of maintenance are critical
- Electrical insulation:PTFE foam’s excellent dielectric properties make it an effective insulator in electrical applications
- Lightweight and flexible: the porous structure contributes to its lightweight nature, allowing for flexibility in design and application
Applications across industries
Our PTFE foam solutions are utilised in various high-performance applications.
