Differences in the production of synthetic rubber and natural rubber Synthetic rubbers are obtained by polymerizing various petrochemicals known as monomers. Some examples are: Sterin butadiene rubber (SBR) obtained by cross-polymerization of strain and butadiene, Butyl rubber (IIR) which is a synthetic rubber obtained by polymerization of isobutylene with isoprene, NB nitrile rubber Which is an oil-resistant synthetic rubber obtained […]
Rubber process oil and tiers Rubber processing oils are obtained from oil (crude oil), this oil is produced by the process of distillation of crude oil resulting from the composition and chemical interactions and extracted materials called raffinate. The composition of the oil has a kinematic viscosity at a temperature of 100 ° C from 32 to 50 cSt and […]
Special space rubber polyisoprene and polybutadiene The discovery that the Ziegler-Nata (Lithium alkyl) catalyst catalyzes the polymerization of isoprene or butadiene in such a way that the cis structure is mainly obtained made it possible to simulate natural rubber by synthesis. Polyisoprene (IR) rubber, which is quite similar to natural rubber, is even superior in some respects such as better […]
Green rubber process oil is also one of the oil products used in the rubber tire industry, which contains less than 10 ppm in terms of the presence of polyaromatic hydrocarbon compounds, especially 8PAH. These oils are of special importance and have been used in world-class countries and European and reputable rubber and tire brands because of their high environmental […]
Malaysia controls almost 90% of the world’s rubber industry. According to the Malaysian Rubber Council, the country’s exports in the first half of 2021 increased by 150% compared to the same period last year. Rubber is used in latex products such as medical gloves, which have increased dramatically with the spread of the corona epidemic. Malaysia Rubber Council announced the […]
The specification of natural rubber or synthetic rubber has been tested, and the results are published in a book of ASTM standards.
Rubber process oil Rubber process oil was prepared from naphthenic base crude feed using extraction or adsorption methods to remove poly nuclear aromatic hydrocarbons (PAHs). Are there any eco-friendly tires? Yes, of course, and the advances in technology will surprise you. Many motorcycle companies have also decided to build environmentally friendly vehicles that are environmentally friendly and durable. In fact, […]
Styrene butadiene rubber emulsion method In this method for styrene butadiene rubber , polymerization is done through free radicals, which is done in both hot and cold states. Styrene butadiene rubber obtained by cold method in the presence of oil or in the presence of oil-soot has high linearity, narrow molecular distribution, high molecular mass and difficult processing. Styrene butadiene […]
Natural rubber Today’s tires are a combination of synthetic tires and natural tires made from rubber trees. But researchers have succeeded in extracting a substance from the dandelion plant that is used to make tires. Dandelions are practically unused plants except for use in a variety of salads, herbal drinks and some beverages. At least until now. But a Russian […]
Synthetic rubber Styrene butadiene rubber While most of the properties of SBR are comparable with NR, but in some respects like heat build-up, tack and gum tensile strength make it inferior to natural rubber. Other disadvantages include: Low elongation at break Low hot tear strength Hysteresis, resilience . But the addition of resins and reinforcing fillers adequately improve these properties. […]
