Low friction coefficient and good wear resist PTFE seal bands assembled in piston
Specifications:
Type of filler -Graphite
*Extremely low coefficient of friction
*Chemically inert
*Usually incorporated with other fillers such as glass or carbon
*Increases wear resistance especially against soft metal
Description:
Manufacturers of PTFE Piston Bands
Used in shock absorber struts
Poly Fluoro Piston Bands are designed for hydraulic and pneumatic equipment. Its unique design
prevents equipment seizures which can arise with other forms of guidance materials.
Poly Fluoro Piston Bands offer extremely low friction and break-away forces. This material is also resistant
to all hydraulic fluids, and is suitable for temperatures up to 200°C.
Poly Fluoro Piston bands are the solution to costly cylinder re-machining and repairs for large diameter
equipment. Coils are available in common sizes and are easy to use, cut and install.
The bearing material is made from PTFE with a 40% Bronze filling and is specifically designed to support
heavy loads. The exceptional physical properties and PTFE lubricants make the piston bands suitable for
use on rams or pistons in reciprocating applications.
Meanwhile we can also add other fillers with PTFE, such as glass fiber, carbon fiber, graphite and so on.
Key advantages include:
Reduces radial movement on both rams and pistons to extend seal life
PTFE lubricant allows for lower coefficient of friction between mating surfaces
Strips can be cut to size from the coil

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
