Rubber tearing permanent deformation refers to the rubber tensile pull off, the specimen will be placed for a period of time (such as 3 minutes), and then the fracture of the two parts of the anastomosis together, the deformation of the part of the increase in the length of the length of the original length of the ratio of the value. The smaller the value, the better the elasticity of the rubber. In order to design rubber products to reduce the permanent deformation of rubber tearing, you can start from the following aspects.
First, choose the appropriate raw rubber varieties of raw rubber varieties of rubber elasticity, strength and tearing permanent deformation performance has an important impact. Therefore, in the design of rubber products, should be based on the products of the use of environment and performance requirements, choose the appropriate species of raw rubber. For example, for products that require high elasticity, you can choose natural rubber or male rubber and other elastic raw rubber.
Second, optimise the formula design formula design is one of the key factors affecting the performance of rubber tensile permanent deformation. By adjusting the formulation of the vulcanising agent, accelerator, filler, reinforcing agent and other components of the type and amount, you can significantly improve the permanent deformation of rubber tear performance.
Third, improve the vulcanisation process vulcanisation process also has an important impact on the performance of rubber products. By optimizing the vulcanization temperature, vulcanization time and vulcanization pressure and other process parameters, you can further improve the rubber's permanent deformation performance.
