АРКМ-15 СКС

Description: Synthetic rubber butadiene-alphamethyl styrene (butadiene-styrene) is obtained by joint polymerization of butadiene with alphamethyl styrene (styrene) in an emulsion at low temperature using a mixture of soaps, rosin and synthetic fatty acids as an emulsifier. VS-1 is used as an antioxidant.

Application: - Rubber SKMS-30 ARKM-15 (SCS-30 ARKM-15) is a general purpose rubber and can be widely used in tire, rubber, footwear and other industries. In terms of technical properties, processing methods, assortment and quality of the ingredients used, SCMS-30 ARKM-15 rubber (SCS-30 ARKM-15) is similar to SBR-1705 type rubber.

Technical specifications
