Fill in polytetrafluoroethylene products
Feastur
 polytetrafluoroethylene
products for filling in is made by pressure and sinter the
polytetrafluoroethylene and bulking agent. This products not
only remain the original feature of pure polytetrafluoroethylene,
but also
increase its hardness, creep resistance, wear hardness,compressive
strength, bending strength, coefficient of heat conductivity,
dimensional stability.
Bulking agent
General bulking agent: fiberglass, molybdenum disulfide,
graphite, copper powder, silicon dioxide.
High-powered bulking agent: polyimide, carbon fiber, polyphenyl
ester, polyphenylene sulfide etc.
Main products:
All kinds of piston ring, deflector ring ,seal ring, bearing,
bush,slide block of valve, guide rail for machine
tool, mechanical seal etc.
Specification
Have custom-made by requirement or drawing.
maximum machining diameter is within 2 meters.
