Product Description

Oill-free Air compressor ptfe piston cup seals

PTFE Ring - We don't offer standard size or stocks, we do custom make only.

Dechengwang produces a complete and full line of PTFE rings for multiple sealing applications in corrosive and high temperature environments(-400°F to +500°F).

These include piston rings, compressor rings, hydraulic seal rings, o-rings, v-rings, ring bearings, back up rings, lantern rings and seals.
PTFE rings can be supplied in Virgin material or with a filler to enhance certain properties.
Regular Filler including: - Glass fiber - Carbon - graphite.
In mechanical applications PTFE with a filler often improves the wear resistance, initial deformation and reduces creep and often increases stiffness and thermal conductivity.

1. The physical and mechanical properties, PTFE is relatively high density, almost non-absorbent. Without tough resilience. It has a very small friction factor, showing excellent lubricity. PTFE static friction factor than the dynamic friction factor is less, and the ultra-low temperature to the melting point, the friction factor is almost unchanged. However, low hardness susceptible to other PTFE materials wear. If it can form a layer on the surface of the grinding material PTFE film, which reduces the amount of wear of PTFE to a considerable extent.

2. heat resistance, thermal stability of PTFE lies in the engineering plastics is extremely prominent. At 200 ℃ to the melting point, the decomposition very slow, very small amount of decomposition, heated at 200 ℃ month, less than a millionth of the amount of decomposition, is negligible. PTFE at -250 ℃ still crisp. Long-term use in -250 ~ 260 ℃.

3. The electrical properties, PTFE is a highly non-polar material, with extremely excellent dielectric properties, prominently when more than 0 ℃, dielectric properties and does not affect the frequency with temperature, humidity and are not subject to influence of corrosive gas . PTFE volume resistivity and surface resistivity is the highest of all plastics, even after prolonged immersion in water, it will not drop significantly, at 100% relative humidity of the air, the surface resistivity remains unchanged. Crystallinity of PTFE at 50% to 80%, the dielectric strength is almost independent of the degree of crystallinity, and having the lowest dielectric constant. PTFE excellent arc resistance.
