• Rubber aging

  The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the comprehensive action of internal and external factors during processing, storage and use, thereby losing use value. It is characterized by cracking, stickiness, hardening, softening, chalking, discoloration, mildew, etc.

• Rubber products

  Rubber products are mixed rubber made from rubber raw materials after mixing in an internal mixer as raw materials. The formula is designed according to the characteristics of the required rubber products during rubber mixing, and the required product hardness is determined. The product is made and molded by a rubber plate vulcanizing machine. After the product is formed, the flashing treatment is performed to make the surface of the product smooth and free of burrs.

• Precautions for rubber product molding

  When rubber products are molded, they can’t be eliminated due to the cohesive force possessed by the elastomer after being pressed by high pressure. When they are molded and released from the mold, they tend to produce extremely unstable shrinkage (the shrinkage rate of rubber varies depending on the type of rubber). After a period of time, it can be calm and stable. Therefore, when a rubber product is designed at the beginning, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, the product size is likely to be unstable and the product…

• Rubber Products

  Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products reproduced from waste rubber. The output of synthetic rubber has greatly exceeded that of natural rubber, and the largest output is styrene butadiene rubber.
