Description

technical field [0001] The invention belongs to the field of organic chemistry. The invention relates to a composition composed of organic polymer compounds as basic materials. Further, the invention relates to a high-performance rubber gasket for radiators and air heaters for automobiles and its manufacturing process . Background technique [0002] The sealing pads in the prior art are mainly composed of nitrile rubber. The sealing pads made of this rubber are resistant to high temperature and easy to age, and are not resistant to cooling medium, have a short service life, and are easy to deform when compressed. And this gasket is prone to oil leakage and is not durable. Contents of the invention [0003] The technical problem to be solved by the present invention is: since the sealing gasket in the prior art is mainly composed of nitrile rubber, the sealing gasket composed of this rubber is resistant to high temperature and easy to age, and is not resistant to cooling m...
