At the time of production, the filler uses filling raw materials such as heavy calcium or talcum powder, which will increase the specific gravity of rubber seals, while good rubber seals will directly use light calcium carbonate as filling raw materials. What is the material of the rubber seal?
Nowadays, it is generally made of imported ternary ethylene propylene rubber. This kind of rubber is relatively resistant to aging. Now the country must use ternary ethylene propylene rubber as a glass curtain wall and construction project.
The rapid test of rubber products in the room, that is, the use of test instruments to simulate the actual use conditions in the test room, conduct a rapid use test, and identify the best product quality. This method is relatively close to the use conditions of the product and can reflect the performance of the product more realistically.
