Synthetic Rubber / SKI - 3
SKI-3 is synthetic isoprene rubber used for the production of rubber goods. It is the nearest substitute for a natural rubber and can be used alone or in combination with other rubbers. SKI-3 is synthetic isoprene rubber with cis-1,4 chains with a content of at least 96%. It can be used independently or in composition with other rubbers for the productions of tires, rubber footwear, sports equipment, bitumen mastics and water-repellent mixtures. Used in the tire and technical rubber industry. This material is staining.
