Applications

PTFE compounds take advantage of the mechanical properties and compression resistance of fillers to meet a variety of needs, mainly low friction and high durability. It is used in a wide range of applications including general industrial uses and automotive industries.

Filler	Characteristics	Examaple of applications
Carbon fiber	Abrasion resistance and mechanical properties in oxygen atmosphere	Compressor piston ring
Bronze	Compression resistance in mechanical applications	Compressor piston ring
Bronze / glass fiber / molybdenum disulfide	Abrasion resistance, compression resistance, and creep resistance suitable for construction machinery	Hydraulic cylinder
Carbon fiber (modified PTFE)	Creep resistance in high-pressure applications	Hydraulic cylinder
Glass fiber	Abrasion resistance, chemical resistance, mechanical properties	Oil sealing
Carbon / graphite	Low wear and abrasion resistance suitable for high-speed applications	Oil sealing

In addition to the above, the following fillers can be combined:

- Glass beads or nano beads

- Carbon fiber (PAN- and pitch-based)

- Conductive filler (standard and food grade)

- PPS and modified PPS

- Polyimide and PEEK　

- Hard carbon (coke) and soft carbon

- Graphite (special grade)

- Bronze (irregular, dendrite, or spherical) etc.

GRADES & FEATURES

We combine various grades of PTFE with a wide variety of fillers to create the best recipe for your needs.

*Based on modified PTFE

All compounds can also be formulated using a modified PTFE base.

<What is modified PTFE?>

It is PTFE with added functions such as creep and flexure resistance, while keeping the heat and chemical resistance of the homotype.
