PCTFE Trifluoro-196℃

PCTFE (Polychlorotrifluoroethylene) is a crystalline thermoplastic fluoropolymer. It is produced by free radical polymerization of trichlorotrifluoroethylene monomers. Its unique molecular structure (-CF₂-CFCl - repeating units) makes it one of the few high-performance materials that can operate stably at -196℃ (liquid nitrogen temperature) for a long time. It possesses excellent low-temperature toughness, extremely low gas/humidity barrier properties, strong chemical inertness, and high dimensional stability. It is indispensable in high-precision fields such as cryogenic engineering, semiconductors, aerospace, and medicine.

Ball valve seat

t is the core sealing component of the ball valve. It is installed inside the ball valve and closely adheres to the ball to form a sealing pair. Its main function is to block or conduct the medium in the pipeline, preventing leakage of the medium. At the same time, it assists in ensuring the smooth opening and closing of the valve. It is one of the key components that determine the sealing performance, service life, and applicable working conditions of the ball valve. It is widely used in various industrial fluid control scenarios.

Flange gasket series

Teflon flange gaskets are non-metallic sealing gaskets composed of a PTFE (polytetrafluoroethylene) coating layer and non-metallic inserts (such as asbestos rubber sheets). They are mainly used for sealing in highly corrosive, highly clean, and pollution-sensitive media. Their structures include V-shaped, U-shaped, and L-shaped types, and are suitable for container, pipeline, and valve connections in the fields of petroleum, chemical, pharmaceutical, and food industries.
