It has a low coefficient of friction and lubrication is not always necessary.
PTFE can work together with other materials like fiberglass or copper to get a better mechanical property.
When PTFE is expanded properly, the fiber changes from hair-like structure to a web-like structure and


become much more stronger while it is much lighter.





It is widely used as flange sealing to joint where strong acid or alkaline or other corrosive.



Competitive Advantage:


Prevents metal to metal scoring and prolongs equipment life


Reduces radial movement on both rams and pistons to extend seal life


PTFE lubricant allows for lower coefficient of friction between mating surfaces


Retrofits existing bearing groves and eliminates unnecessary modifications


Available in common groove width dimensions, minimizing inventory costs


Strips can be cut to size from the coil
