Rubber sealing parts
We produce and supply sealing parts from silicone rubber, fluororubber, NBR, PU, PTFE, POM and nylon. Some of our sealing parts are produced in compliance with international standards, which ensure no pressure loss or leakage in 520 km travel length and 400 thousand operation cycles. Our sealing rings for vulcanization tanks in machinery manufacturers provide good resistance to heat, appropriate elasticity and excellent tightness.
I. Features
1. Good resistance to abrasion, squeezing and impact, good adaptability and easy to install.
2. High elasticity and resilience, small compression deformation, and accurate size.
3. Appropriate mechanical strength, including tensile strength, elongation and tear strength.
4. Stable performance, no swelling in media and small thermal contraction (Joule effect).
5. No corrosion to contact surface and contamination to media.
II. Use
It is widely used as sealing parts in industries, such as marching tool, shipbuilding, automobile, aviation equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, drilling machinery, plastics machinery, agricultural machinery and various instruments and devices.
