Sterseal material industry
Jiashan Itaflon Fluoropolymer Technology Co., Ltd. supplies the Hyperflon® Hyperion series filled modified PTFE materials for Sterfeng. Itaflon seal filled modified PTFE material performance is excellent, can be used in the vast majority of chemical fluids, solvents, as well as hydraulic oil, lubricating oil, its swelling is very small so can long-term play sealing performance, provide the full condition of static or dynamic (reciprocating or rotating motion) PTFE seal modified material, the use of temperature range from refrigerant to 300℃, The pressure per unit area can reach 700kg, and the moving speed is as high as 20m/s.
- Itaflon special seal material advantage
- Low friction coefficient
- Low thermal expansion coefficient
- Excellent rebound rate
- Long reciprocating and rotating life under high pressure
