PTFE6 (polytetrafluoroethylene balls)
PTFE balls (PTFE6) are widely used in chemical pumps, oilfield pumps, nuclear power, aerospace, military, and other products.
 Characteristics: PTFE is a white opaque waxy powder with a density of 2.14~2.20g./cm3.
Features: It is heat-resistant—usable at temperatures ranging from 200 to 260 degrees Celsius, cold-resistant—remains flexible at -100 degrees Celsius; corrosion-resistant—resistant to aqua regia and all organic solvents; weather-resistant—has the best aging resistance among plastics; high lubricity — has the lowest friction coefficient (0.04) among plastics; non-stick — has the lowest surface tension among solid materials and does not adhere to any substance; non-toxic— has physiological inertness.
Precision Grade:G0—G4
Specifications:1mm—60mm
