The Compound of Rubber

05 Feb 2021

Rubber compound is a process of combining raw rubber and compounding agent according to the performance requirements of products,considering factors such as processing technology performance and cost.The general compound system includes raw glue, curing system, reinforcing system, protection system, plasticizing system, etc.. Sometimes it also includes some other special systems such as flame retardant, coloring, foaming, antistatic, conductive and other systems. With raw rubber (or with other polymers) as the parent material or matrix material, after vulcanization system, that is, with rubber macromolecules play a chemical action, the rubber form linear macromolecules into three-dimensional network structure, improving the performance of rubber and making its formation stable; Using the reinforcing filling system, we add carbon black and other reinforcing agents or other filling agents into rubber,which will improve rubber mechanical properties and performance, or reduce the cost of products; At the same time, the protection system improves the service life of the products. The aging-resistant agent is added to delay the aging of rubber; Finally, the plasticizing system reduces the hardness of the products, the viscosity of the mixed rubber and the rubber processing performance.
