Pure PTFE Cord: Sealing solution for critical environments

Braided pure PTFE (polytetrafluoroethylene) cord is a high-performance engineering material designed for sealing applications in industries requiring chemical resistance, durability, and performance under extreme conditions. Widely used in chemical, pharmaceutical, food, and power generation processes, its composition ensures reliable sealing in demanding environments.

Key advantages of pure PTFE cord:

• Total chemical resistance: Inert to most acids, bases, solvents and corrosive agents, making it an ideal solution for aggressive environments.
• High thermal tolerance: It withstands temperatures from -240 °C to +260 °C, allowing its use in equipment subjected to continuous thermal variations.
• Low friction: Its non-stick surface reduces wear and facilitates installation, decreasing friction between moving surfaces.
• Food and drug compatibility: Thanks to its purity, it is suitable for use in the food and pharmaceutical industries, complying with safety regulations.
• Versatile applications: Used in pump packings, valves, heat exchangers and chemical reactors, ensuring efficient static and dynamic sealing.
• It does not age or degrade easily: Its stable molecular structure resists weathering, UV radiation, oxidation, and compression deformation.

Common uses:

• Sealing in valves for passing chemical or corrosive fluids.
• Packing in centrifugal or reciprocating pumps.
• Sealing components in food processing plants and laboratories.
• Application in static joints subjected to pressure and high temperatures.
