What is the raw material of artificial natural rubber?
Tapioca, American rubber, India fig, African cane gum and Brazil trefoil rubber. But it has the advantages of high yield, good quality, long gum production period, low cost of making rubber and convenient processing. It is only one kind of Brazil trefoil rubber. Its yield has accounted for more than 99% of the total output of natural rubber. Made from synthetic rubber.
Rubber is divided into natural rubber and synthetic rubber. Natural rubber is a natural material. Its main chemical composition is polyisoprene, and synthetic rubber belongs to organic synthetic material.
Synthetic rubber is composed of different monomers under the action of the initiator, the polymerization of polymers of variety, monomer, styrene, butadiene acrylonitrile, isobutylene, chloroprene etc.. There are four kinds of polymerization process: emulsion polymerization, solution polymerization, suspension polymerization and bulk polymerization.
For example, styrene butadiene rubber is a synthetic rubber made of styrene and butadiene, so it is called SBR. Similarly, nitrile rubber is called NBR, and chloroprene rubber is called CR. China naming methods: for the copolymer is in the corresponding suffix monomer in copolymer rubber such as butadiene styrene copolymer as rubber, styrene butadiene rubber; for the homopolymer, called "poly" before the corresponding monomer in the polymer, and after decorated with "rubber" such as CIS polyisoprene rubber (referred to as ISO -1,4- isoprene rubber) CIS polybutadiene rubber (referred to as -1,4- butadiene rubber) etc.. In addition, there are popular naming methods, that is to take the polymer except hydrocarbon specific elements or groups to name. For example, the rubber formed from Alpha Omega - two chloro hydrocarbons (or alpha, Omega two chloro ethers) and sodium polysulfide is commonly called polysulfide rubber, and the rubber obtained by copolymerization of isobutene and a small amount of isoprene is often called butyl rubber
