Carbon fiber filled PTFE Bands consistency size , ROHS report
ptfe guide strips that cut into wear ring is to guide the piston and piston rod of a hydraulic cylinder,
absorbing transverse foree. At the same time, it prevents metal to metal contact, optimizing the
performance of the sealing system.
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.

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