summary
The material is a new sealing material, which is uniformly coated with a rubber layer on the surface of the metal substrate through a specific production process; The material has good heat resistance, durability and a very low pressure set. Compared to traditional non-metallic sealing materials, this material has a relatively long service life, so it is often used in environments with higher pressures, higher temperatures and more demanding sealing requirements.
