In modern industrial production, high-temperature environments and complex chemical transfer systems impose stringent requirements on piping materials. Conventional materials often fail to withstand extreme heat and chemical corrosion, while PFA tubes (Perfluoroalkoxy tubes) emerge as the ideal solution due to their unique properties. Shanghai Cunjian, a professional PFA tube supplier, has built a strong reputation in the industry with its high-quality products and services.
PFA tubes can operate stably within a -200°C to +260°C range, with short-term peak resistance up to 300°C. Their carbon-fluorine (C-F) bond energy (485 kJ/mol) ensures an ultra-high thermal decomposition temperature (>380°C) and an extremely low thermal expansion coefficient (12×10⁻⁵/°C), minimizing deformation risks under high temperatures.
Shanghai Cunjian enhances product performance through patented modification technologies:
Nano-scale heat-resistant fillers increase tensile strength by 15% at 260°C.
Precise crystallinity control reduces deformation risks.
Special anti-aging formulations extend high-temperature service life.
In semiconductor CVD processes, their PFA tubes have helped clients:
✔ Increase wafer yield by 15%
✔ Save over ¥2 million annually in maintenance costs
✔ Extend system operation cycles from 3 months to 2 years
PFA tubes resist nearly all strong acids (e.g., sulfuric acid, hydrochloric acid), alkalis (e.g., chlor-alkali solutions), and organic solvents, preventing corrosion, swelling, or cracking. The fluorine atoms in their molecular structure form a robust protective barrier against chemical erosion.
Shanghai Cunjian’s PFA tubes combine corrosion resistance with flexibility and mechanical strength, adapting to complex installation environments. In chemical production, they significantly enhance safety, reduce leakage risks, and minimize environmental hazards.
