PTFE Products Precision Machining Parts

PTFE is formed by free radical polymerization of tetrafluoroethylene. Industrial polymerization is 

carried out with stirring in the presence of a large amount of water to dissipate the heat of 

reaction and to facilitate temperature control. Polymerisation is typically carried out at 40-80 °C 

and pressures of 3-26 kgf/cm2. Inorganic persulfates and organic peroxides can be used as 

initiators or redox initiation systems can be used. Each mole of tetrafluoroethylene is exothermic 

during polymerization. Perfluorosurfactants, for example perfluorooctanoic acid or its salts, must 

be added for dispersion polymerization.
PTFE CNC Machining Parts: the PTFE (polytetrafluoroethylene) non-stick coating can be 

used continuously at 200 °C, with a maximum operating temperature of 260 °C, an extremely 

low coefficient of friction, good abrasion resistance and good chemical stability.
