Rubber products: It refers to the activities of producing various rubber products with natural and synthetic rubber as raw materials, and also includes the rubber products reproduced from waste rubber.

The basic characteristics are as follows:

1. When rubber products are molded after large pressure pressing, the cohesive force inherent in the elastomer cannot be eliminated, which often produces extremely unstable shrinkage when molding out of the mold (the shrinkage rate of rubber varies depending on the rubber species), and must be eased and stabilized after a period of time. When a rubber product is designed at the beginning, regardless of the formula or mold, needs to be carefully calculated to ensure quality.

2. Rubber is a hot-soluble thermosetting elastomer, while plastic is a hot-soluble cold-setting. The temperature range for molding and curing of rubber is quite different due to the different types of vulcanization bodies, and can even be affected by climate change, indoor temperature, and humidity. The production conditions of rubber products need to be moderately adjusted at any time.

3. Rubber products are made from rubber raw materials after refining in the rubber mixing machine as raw materials, and the formula is designed according to the required characteristics of rubber products during refining, and the required product hardness is set. The product is molded by the rubber plate vulcanizing machine. After molding, the products are processed with flying edges to make the surface smooth and burr-free.

4. Rubber products aging test belongs to the aging test category, rubber aging refers to the rubber and products in the processing, storage, and use process, due to the comprehensive effect of internal and external factors caused by the performance of structural changes, and then lose the value of the phenomenon. Performance for cracking, sticky, hardening, softening, chalking, discoloration, mold, etc.
