What is the purpose of rubber compounding?

In order to adapt to different conditions of use, obtain different properties, and in order to improve the performance of rubber products and reduce costs, it is necessary to add different compatibilizers to the raw rubber. Mixing is the process of mixing the plasticized raw rubber with the compounding agent and putting it in the refining machine, so that the compounding agent can be completely and evenly dispersed in the raw rubber through mechanical mixing. Mixing is an important process in the production of rubber products, if the mixing is not uniform, it can not give full play to the role of rubber and with the agent, affecting the performance of the product. The rubber obtained after mixing, people called mixing rubber, it is the manufacture of a variety of rubber products, semi-finished materials, commonly known as rubber, usually sold as a commodity, the buyer can use the rubber directly processed molding, vulcanization made of rubber products required.
