Product Description

Oill-free Air compressor ptfe piston cup seals

Owing to the presence of our expert team members, we have been able to manufacture and supply a wide assortment of cup seal. These are extensively used for steam, oil, water, in other chemical applications. Our cup seals are extensively acclaimed as a perfect pressure-energized seals which ensure good flexibility. These can be easily fitted with a high degree of preload to maintain sealing at very low pressures. Following the demands of clients we provide these in various dimensions and specifications.

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.
