Description

PTFE balls is produced by free radical polymerization.Industrial polymerization is carried out by stirring in the presence of a large amount of water to disperse the heat of the reaction and to facilitate temperature control.Polymerization is generally carried out under 40 ~ 80℃and 3 ~ 26KG/CM Mpa.Inorganic persulphates and organic peroxides can be used as initiators, and REDOX initiators can also be used. Per mole of tetrafluoroethylene polymerization heat release 171.38kJ.

Advantage

• Friction coefficient, is almost the lowest in all solids, and has good high temperature resistance, strong chemical stability, almost not eroded by any chemicals.
• The surface is non-viscous and excellent electrical insulation performance, in a wide frequency range of dielectric constant stability and minimum value.
• Excellent aging resistance, oxygen, ozone, ultraviolet action, incombustible, minimal water absorption, make ptfe ball has a long product life.

Application

PTFE balls are used in chemical industry, machinery, electronics, equipment, military industry and aerospace.
