Polytetrafluoroethylene (PTFE) has excellent sealing properties and corrosion resistance. However, due to its inherent poor creep resistance, PTFE materials can leak at the seal over long-term use because of the creep of the gasket. To improve this drawback of ordinary PTFE, people add other materials such as graphite and glass fibers to PTFE to enhance its creep resistance and improve the durability of PTFE gaskets. Gaskets with other materials added to ordinary PTFE are called modified PTFE.Main properties

Production Process for PTFE Rod As Following Steps :
Modified PTFE, due to its excellent chemical corrosion resistance, can withstand the corrosion of strong acids, strong alkalis, and various chemical solvents, making it an ideal choice for manufacturing key components such as chemical equipment, pipeline systems, and valve seals.
In the machinery industry, modified PTFE can serve as anti-sticking and lubricating materials for components like bearings, sliders, and guides, significantly improving the operational efficiency and service life of machinery.
Modified PTFE also possesses superior insulation properties and is widely used in the manufacturing of electrical insulation layers for wires and cables, capacitors, and other electronic components, providing strong assurance for the safety and stability of electronic products.
