Our PTFE range includes:
Gaskets, Piston Seals, Rod Seals, Wipers, Bearing Strips, Spring
Activated Seals, Rod, Back up Rings & Strips, Ropes
Advantages:
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.
Applications:
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
