Flourine Seal
The choice of filled PTFE resin molded products in order to improve certain properties of the product will be suspended PTFE resin mixed a variety of fillers, such as glass fiber, carbon fiber, graphite,MoS2. Compared with the many advantages of a high compressive strength, more wear and enhance thermal conductivity and reduce thermal expansion of PTFE filled with pure PTFE.
Main Performance
Creep resistance, chemical resistant, low friction coefficient, low wear, rigid toughness, resistance to the climate good performance
Application
Dynamic gaskets, valve seats, seals, bearings, slider, piston rings
