There are three types of rubber materials for automobile sealing strips: dense rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. The rubber material of the sealing strip is mostly used for aging resistance, low temperature resistance, moisture resistance, and ch... read more
Rubber sealing strips can be classified according to several methods such as cross-sectional shape, vulcanization method, application location and purpose, and materials used. (1) Discontinuous vulcanization method (after cutting the extruded rubber strip to a certain length, put it in a vulcanizing... read more
Fluorine rubber has high temperature resistance, can be used in the environment of -30℃-+250℃, resistant to strong oxidants, oils, acids and alkalis. Usually fluorine rubber is used in high temperature, high vacuum and high pressure environment, but also suitable for oil environment. Due to its vari... read more
1. Natural rubber NR rubber gaskets have good corrosion resistance to weak acids and alkalis, salt and chloride solutions, but poor corrosion resistance to oils and solvents, and are not recommended for ozone media. The recommended working temperature is -57℃~120℃. Applications, inorganic salts, amm... read more
Ethylene-propylene rubber EPDM is made by copolymerization of ethylene and propylene, so it has excellent heat resistance, aging resistance, ozone resistance, and stability, but it cannot be sulfurized. In order to solve this problem, a small amount is introduced into the EP main chain It has the th... read more
