Demand for synthetic rubbers in this report is split by the application areas tires, automotive applications, industry and construction, modification of materials (that is the admixture with other materials) as well as by the group of other applications. The tyre base is 100% natural rubber. Compared to natural rubber, SBR has better processability, heat aging and abrasion resistance but is inferior in terms of elongation, hot tear strength, hysteresis, resilience and tensile strength. Natural rubber is obtained from the milky white fluid called latex, found in many plants; synthetic rubbers are produced from unsaturated hydrocarbons. Typically tyre tread is 50% natural rubber and 50% styrene-butadiene rubber (SBR). Thus, the type of rubber made from chemicals to act as the substitute for natural rubber is the synthetic rubber. Chemistry, Manufacture and Applications of Natural Rubber is a comprehensive resource for academics, chemists, chemical engineers, mechanical engineers, and other professionals in the rubber industry, as well as those industries, including automotive, civil, and medical engineering, using natural rubber products.
