What is PTFE lining?

2025-10-02

What is PTFE lining? If you're a procurement specialist sourcing industrial components, you've likely encountered challenges with corrosion, contamination, or chemical resistance in equipment. PTFE lining—a protective layer of polytetrafluoroethylene applied to the inner surfaces of vessels, pipes, or valves—is the game-changer. It offers unmatched non-stick properties, high-temperature tolerance, and resistance to aggressive chemicals, extending equipment lifespan and reducing downtime. At Ningbo Kaxite Sealing Materials Co., Ltd., we specialize in high-performance PTFE linings that solve real-world industrial problems, ensuring reliability and cost-efficiency for your projects.
