Features:1.Excellent non-sticky property---It easier to remove those resin, dopes, oil and other sticky things.2.Good mechanical property with no distortion and low friction coefficient.3.Excellent insulation property.4.Materials like carbon, graphite and glass fiber can be filled.5.Virgin uhmwpe resin materials are necessary.6. Strong anti chemical properties7. Work under extreme temperatureSeal Gasket to be machined by moulded tubes which can perform very well under the very low temperature such as liquid helium (-269 ℃) and still have the good features. Therefore, it is often used as low temperature resistance parts of the nuclear industry.Material: UHMWPEWorking temperature: -265℃ -- 80℃Through the sample charge is high, it is able for us to refund it back to you when the order is placed afterwards.The washer can be CUSTOMIZED.(Tolerance: +0.5mm)
