Introduction to RPTFE Seal
Reinforced Polytetrafluoroethylene (RPTFE) seals are high - performance sealing products. RPTFE is a modified form of PTFE, which has excellent chemical resistance, low friction coefficient, and wide - temperature - range stability. These seals are widely used in various industries such as chemical processing, oil and gas, and food and beverage. They can effectively prevent the leakage of fluids and gases, ensuring the normal operation of equipment. RPTFE seals are especially suitable for applications where high - pressure, high - temperature, and corrosive media are involved.
