Working Temp.


Melting point


Produce Max Temp.








Mechanical properties: carbon fiber filled PTFE ring increases the hardness of PTFE and reduce cold


flow or creep. Tensile strength and elongation usually are reduced depending on the filler type and




Thermal properties: carbon fiber filled PTFE ring increases thermal conductivity and also reduce liner


coefficient of thermal expansion then increase thermal dimensional stability.


Type of filler Graphite:


1. Extremely low coefficient of friction


2. Chemically inert


3. Usually incorporated with other fillers such as glass or carbon


4. Increases wear resistance especially against soft metal


Inorganic filler: carbon fiber, Bronze, Glass fiber, etc


This carbon fiber filled PTFE rings are widely utilized into oil free air compressors. Most of rings are made


of self-lubricating materials such as virgin PTFE and filled PTFE compounds like carbon filled PTFE and


graphite filled PTFE, etc. All above grades are available


Type: Piston ring, straight cut piston ring, diagonal piston ring, stepped cut piston ring, two piece piston


ring, etc.


Chemical properties     


Carbon fiber filled PTFE ring: it can resistant to almost all of the hydraulic medium, solvents, and various


chemical mediators, has a very low coefficient of friction, no creeping phenomenon. Ozone resistance,


weather resistance is excellent
