Glass Fiber Filled PTFE Teflon Plastic Ball
Glass Fiber Filled Teflon PTFE Plastic Ball KXT PB 150
Our high quality PTFE Teflon Balls are well suited for industrial applications that require an inert, chemically resistant ball, with the purity,
specific gravity and wide operating temperature ranges of PTFE (polytetrafluoroethylene) that other plastic balls materials don't provide.
Applications include PTFE balls used in chemical handling pumps, check valves, ball bearings, volume displacement balls for chemical
baths and many other uses.
PTFE Balls can be filled with Glass fiber, Carbon, Graphite, Bronze and Colors
10% Glass 10% Carbon filled-PTFE (A blend of glass fibers & carbon with virgin PTFE)
15% Glass filled-PTFE (15% Glass Fibers compounded with virgin PTFE)
25% Glass filled-PTFE
100% Virgin PTFE
Bronze filled PTFE
