Sbr Rubber

Handbook of Styrene Butadiene Rubber

Styrene-butadiene rubber (SBR) is one of the most versatile copolymer rubber compounds. It consists of the organic compound styrene and the chemical budatiene, with the amount of budatiene usually being about three times more than the amount of styrene. SBR is a stable synthetic rubber that is resistant to abrasion. It is used in a wide variety of products, such as automobile tires, childrens toys, shoe soles and even chewing gum. SBR is produced either through ionic polymerization of a solution or as an emulsion through free radical polymerisation. Also known as emulsion stryrenebutadiene rubber (E-SBR), this product was first developed in the 1930s by I.G. Farbenindustrie in Germany. It was created through an emulsion procedure that used polymerization as the means of producing a material that had a low reaction viscosity but had all the attribute of natural rubber. SBR was very cost-effective and was used to stretch dwindling natural rubber resources, especially in tire manufacturing at a time when tires were made of solid rubber.

Styrene Butadiene Rubber Production - Cost Analysis - SBR E11A

This report presents a cost analysis of Styrene Butadiene Rubber (SBR) production via cold emulsion polymerization process. The process examined is a typical continuous cold emulsion process for producing a non-staining, non-oil extended SBR grade (similar to 1502). In this process, an emulsion comprising water, styrene and butadiene monomers is polymerized into a latex, which is then coagulated to form the styrene-butadiene rubber. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) This report was developed based essentially on the following reference(s): "Styrene-Butadiene Rubber", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Polymerization, Styrene Butadiene Rubber, eSBR, BD
