VT04 RPTFE Stem Spring Energzied Seal

Reinforced polytetrafluoroethylene, referred to as RPTFE. Although PTFE has excellent comprehensive properties, it has disadvantages such as low mechanical strength, large linear expansion coefficient, poor wear resistance, poor creep resistance, and poor thermal conductivity. RPTFE is to fill PTFE with a reinforcing agent to improve the mechanical properties of the material, to expand the application range of its material, to overcome the shortcomings of PTFE.
