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

Characteristics

1. When rubber products are molded, they are pressed under high pressure, which cannot be eliminated due to the internal cohesion of the elastomer. When molding, unstable shrinkage is often produced (the shrinkage rate of rubber varies due to different rubber species), and it can be gentle and stable after a period of time. Therefore, when a rubber product is designed at the beginning, regardless of the formula or mold, it is necessary to carefully calculate the coordination. If not, it is easy to produce unstable product size and low product quality.
2. Rubber is a hot-melt thermosetting elastomer, while plastics are hot-melt cold-hardened. Due to the different types of vulcanized rubber, the temperature range of its molding and curing is also quite different, and it can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted at any time, if not, the quality of the products may be different.
3. Rubber products are mixed rubber made from rubber raw materials after internal mixer mixing. When mixing rubber, the formula is designed according to the characteristics of the required rubber products and the required product hardness is determined. The product is molded by a rubber flat vulcanizer. After the product is formed, flash treatment is carried out to make the surface of the product smooth and free of burrs.
4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance structure of rubber and its products is changed due to the comprehensive effect of internal and external factors in the process of processing, storage and use, thus losing the use value. It is characterized by cracking, sticking, hardening, softening, powdering, discoloration, mildew, etc.

Rubber products refers to the production of various rubber products from natural and synthetic rubber.
