PTFE Balls are well suited for industrial applications that require an inert, chemically resistant ball, with the purity, specific gravity and wide operating temperature range of PTFE (polytetrafluoroethylene) that other plastic ball materials don’t provide. These solid plastic balls are used in check valves, relief valves, float valves, and everything from carburetors to toggle switches and more. They also work well for many manufacturers as light load ball bearings.
The Properties of PTFE
PTFE * Excellent chemical resistant * Water absorption: 0 * Specific gravity: 2.13 to 2.22 * Cubic inches per lbs.: 12.6 to 13.2 * Rockwell hardness (Shore D): 50 to 65 * Maximum temperature: 550°F * Tolerance: ±0.001inch * Sold in increments of 10 only Available Materials: Virgin Grade PTFE Modified PTFE Glass filled-PTFE (5~25% Glass Fibers compounded with virgin PTFE) Other PTFE material compounds are possible upon request.
> Heat resistance
can work stably from -180℃ to +260℃.
> Excellent non-stickiness
Easier to remove resins, dopants, oils, and other sticky materials.
