Refrigeration equipment: PCTFE sealing gaskets can be used in valve components of refrigeration equipment, such as valve seats, valve stems, and seals, to ensure sealing effectiveness at low temperatures.
Liquid Nitrogen and Liquid Oxygen System: PCTFE sealing gasket is suitable for valve sealing in cryogenic systems such as liquid nitrogen and liquid oxygen, providing reliable sealing performance.

Typical application scenarios
Energy field: LNG storage and transportation, liquefied natural gas refueling system. Industrial gases: storage and transportation pipelines for liquid nitrogen, liquid oxygen, and liquid helium. Aerospace: liquid hydrogen, liquid oxygen fuel control system.
Research facilities: Superconducting equipment, low-temperature experimental equipment, medium control.

Performance characteristics
Low temperature resistance: PCTFE sealing gaskets can maintain their physical and chemical properties at extremely low temperatures, with a long-term use temperature range of -200 ℃ to 120 ℃, suitable for ultra-low temperature environments.
Chemical stability: PCTFE has excellent chemical stability and can resist corrosion from various acids, bases, oils, and organic solvents, making it suitable for sealing in contact with highly corrosive media.
Mechanical strength and hardness: PCTFE has higher mechanical strength and hardness than polytetrafluoroethylene (PTFE), providing reliable sealing performance in high-pressure systems.
Airtightness: PCTFE has excellent airtightness and is suitable for low-temperature valve applications that require high airtightness.
