Description

technical field [0001] The invention relates to the technical field of ball valve sealing, in particular to a high-strength fluorine rubber. Background technique [0002] Rubber seals are a general basic component in sealing devices Rubber seals are a type of rubber products widely used in sealing technology. Because of its very small elastic modulus, high elongation, and air resistance, it is widely used for installation on various mechanical equipment. Due to the harsh environment of use, such as low temperature, etc., the seal will be damaged. [0003] The mechanical properties in the prior art are poor and cannot meet the needs of actual use, so it is urgent to design a rubber seal with high mechanical properties to solve the problems in the prior art. Contents of the invention [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a high-strength fluororubber. [0005] The object of the present i...
