What Are the Application Fields of PTFE High-Temperature Fabric?

PTFE high-temperature fabric (also known as Teflon high-temperature cloth or PTFE high-temp fabric) is a high-performance composite material manufactured using fiberglass as the base substrate coated with polytetrafluoroethylene (PTFE) resin. Leveraging its outstanding properties — including high-temperature resistance (-70°C to 260°C), strong chemical corrosion resistance, non-stick performance, electrical insulation, and weatherability — it is widely used across more than 20 industrial and everyday application sectors, serving as the core solution for high-temperature, high-corrosion, and high-cleanliness environments.
