Description:
Smooth surface
High mechanical strength
High temperature application range
Chemical and corrosion resistance
Low coefficient of friction
Fine finish by CNC machined
We can manufacture various PTFE irregular shaped parts by compression molding and CNC machining
for the applications that require high purity, chemical resistance and thermal properties. Quality meets or
exceeds the highest standards in this field.
PTFE has excellent corrosion resistance, but under load will creep phenomenon of cold flow, ordinary
PTFE materials are hard, toughness is poor, but our factory the production of PTFE Washer is made
through a special process modification, comprehensive performance is greatly improved, especially the
creep resistance.
PTFE Washer Product Category:
PTFE gasket, PTFE bars, PTFE pads, PTFE insulation sleeve, PTFE tape, PTFE insulation pads
