PCTFE Sleeve

PCTFE (Polyvinylidene fluoride) is a high-performance fluoroplastic. Its molecular chain contains both fluorine and chlorine atoms, combining the corrosion resistance of fluoroplastics with the polarity of chlorine atoms, giving it excellent comprehensive performance. PCTFE is widely used in high-end fields such as aerospace, low-temperature sealing, semiconductors, chemical fluids, medical devices, etc. Our company can provide hundreds of PCTFE blank sleeves for processing valve sealing components of various sizes, such as valve seats, gaskets, sealing rings, etc.

Product Features
● Excellent low-temperature resistance: maintains good mechanical strength even at extreme low temperatures, suitable for ultra-low temperature environments such as liquid nitrogen and oxygen
● Excellent chemical corrosion resistance: has strong resistance to strong acids (such as concentrated sulfuric acid, nitric acid), strong bases, organic solvents, and oxidants
● High mechanical strength and dimensional stability: hardness and compressive strength are better than PTFE (polytetrafluoroethylene), and Outstanding cold flow resistance and creep resistance, suitable for precision mechanical component manufacturing
● Excellent gas barrier properties: extremely low water vapor transmission rate, one of the best barrier materials in transparent plastic films, suitable for high vacuum sealing and moisture-proof packaging
● Good electrical insulation: PCTFE has excellent dielectric properties and is a good insulation material for electrical and electronic applications.
● Radiation and weather resistance: can be exposed to ultraviolet and nuclear radiation environments for a long time, with no significant degradation in performance, suitable for nuclear industry and outdoor applications
● Transparency: The transparency and UV resistance of PCTFE make it suitable for optical applications, including lenses and windows that require durability and transparency
● PCTFE sleeve specifications range: outer diameter Φ 34~Φ 1000mm, height: 50~200mm
