At what temperature can PTFE be used stably

Polytetrafluoroethylene has a high degree of chemical stability and excellent chemical resistance, such as resistance to strong acids, strong alkalis, and strong oxidants. , Has outstanding heat resistance, cold resistance and friction resistance. The long-term use temperature range is -200-+250℃, and it has excellent electrical insulation performance and is not affected by temperature and frequency. In addition, it has the characteristics of no pollution, no water absorption, and no burning. Suspension resins are usually molded and sintered. The finished rods, plates or other profiles can also be further processed by turning, drilling, milling and other machines. Bars can be stretched by turning to make oriented films. Teflon gasket is a polymer of tetrafluoroethylene. The English abbreviation is polytetrafluoroethylene. The product name is Teflon.
