The molding material provided by the invention has good anti-compression performance and wear resistance.

Description

technical field [0001] The invention relates to the field of materials, in particular to a molding material. Background technique [0002] Polytetrafluoroethylene is commonly known as "the king of plastics". At present, various polytetrafluoroethylene products have played a pivotal role in the fields of national economy such as chemical industry, machinery, electronics, electrical, military industry, aerospace, environmental protection, etc. It is the most corrosion-resistant plastic in the world today. One of the plastics with the best performance, except for molten metal sodium and liquid fluorine, it is resistant to corrosion by all chemicals, strong acids and alkalis, various organic solvents, etc. It is widely used in sealing materials and pipes in corrosion-resistant engineering. However, the existing polytetrafluoroethylene molding material has disadvantages, and the conveying pipeline product made of the existing molding material has the problems of low compressive s...
