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.
