The main raw material of synthetic rubber

The main raw materials of synthetic rubber are petrochemical products, especially olefins. ‌ These olefins are mainly produced by cracking or cracking of petroleum. The main monomers include butadiene, styrene, acrylonitrile, isobutene and chlorobutadiene. ‌

The production process of synthetic rubber consists of the following steps: First, through the olefin in the petrochemical product as a monomer, polymerization is carried out under the action of an initiator. There are many polymerization processes, including emulsion polymerization, solution polymerization, suspension polymerization and bulk polymerization. The polymerized material needs to go through post-treatment steps such as removal of unreacted monomers, condensation, dehydration, drying and packaging to finally make finished rubber.

Properties and applications of synthetic rubber: Synthetic rubber has high elasticity and diversified physical properties, and is widely used in various industrial and life fields. Among the three major synthetic materials, its yield is only lower than that of synthetic resin and synthetic fiber.
