2, the surface of the gasket body does not allow the impact of the sealing performance of the scars, voids, bumps and rust defects.

3, compression rate, rebound rate and sealing performance are important performance indicators for gaskets. In general, under the premise of satisfying compression ratio requirements, the higher the rebound rate is, the better; and it meets the requirements of the rebound rate standard. Under the premise, the test value of the compression ratio is also larger. Should choose a product with good sealing performance, moderate compression ratio and the greatest rebound rate.
