SBR 1502


What is SBR 1502?

Styrene-Butadiene Rubber “SBR 1502” is produced by a technology of cold emulsion copolymerization based on soaps of rosin and fatty acids and contains 23.5% of chemically bonded styrene . SBR 1502 is a cold polymerized, 23.5% styrene SBR polymer made with a mixed-acid emulsifier, non- staining stabilizer, and salt-acid coagulation.1502 has very good properties such as process ability, abrasion resistance, less tendency to scorching. SBR 1502 exhibits the excellent tensile strength, abrasion resistance, flexibility and recovery prop- erties that are characteristic of “cold” rubbers.

uses of SBR 1502

It is general purpose rubber. Whatever it is widely used in tire, rubber technical, shoe, cable and other industries for production of automobile tires and tubes, wide assortment of rubber technical articles, white and colour shoes, cable and children toys castings and so on.

Packing of SBR

Normally it packed in 35 ±0.5 KG bales wrapped with polyethylene film, and in 36 bales per crate (1260±18 KG).
