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.

| 0-14 |
PTFE Seal thickness | MM | 0.5(±0.10)/side |
Gasket Thickness | MM | 2(±0.10) or as customers' request |
| Advantages | 1. Good abrasion resistance, long lifetime. |
| 2. High structure strength, certain degree elasticity. | |
| 3. Without metallic contact of the sliding surfaces. | |
| 4. Control the machine’s vibration. | |
| 5. Absorb the size’s load. | |
| 6. Enlarge the clearance of seal’s extrusion. | |
| 7. Simple groove design, and high load capacity. |
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
