Black car door rubber grommet is protecting wiring or allow movement or motion while preventing damage during use.The design principle is easier to assemble and better sealing test.

1. When the rubber product is molded, it is not able to eliminate the cohesive force prepared by the elastic body after being pressed by a large pressure. When forming the mold, it tends to produce extremely unstable shrinkage. The shrinkage rate of the rubber varies depending on the rubber type. The rubber product takes a while to be gentle and stable. Therefore, when a rubber product is designed, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, it is easy to produce unstable product size, resulting in low product quality.
2. Rubber is a hot-melt thermosetting elastomer, and plastic is hot-melt and cold-set. Because of the different types of sulfides, the temperature range of the curing of rubber is also quite different, even due to climate change, indoor temperature and humidity. Therefore, the production conditions of rubber products must be adjusted at any time. If not, the quality of the products may be different.

Ethylene propylene rubber is a copolymer of ethylene and propylene. Therefore, heat resistance, aging resistance, ozone resistance and stability are very good, but sulfur cannot be added. To solve this problem, the EP main a small amount of a double-stranded third component is introduced into the chain to form an EPDM, which is generally used at a temperature of -50 to 150 ° C. Excellent resistance to polar solvents such as alcohols and ketones. Advantages: Good weather resistance and It is ozone-resistant, has excellent water resistance and chemical resistance, and can be used with alcohols and ketones. It is resistant to high-temperature steam and has good impermeability to gases. Disadvantages: Not recommended for food use or exposure to aromatic hydrogen. Seals or parts for sanitary equipment seals in high temperature steam environments. Rubber parts in the brake (brake) system. Seal in the radiator (car tank).
