[0002] Butyl rubber is a synthetic rubber with unique properties. The film made of it plays an auxiliary role in automobiles. For example, at the connection between the fuel tank and the fuel pipe, the sealing gasket plays a crucial role. The butyl film sealing gasket can prevent fuel from leaking at the connection between the fuel pipe and the fuel tank. Since a certain pressure will be generated during the fuel transportation process, the sealing gasket needs to withstand this pressure and maintain the seal.
