DESCRIPTION :
The butadiene-alpha-methyl styrene ( styrene ) rubber is
produced by emulsion copolymerization obutadiene and alpha-methyl
styrene ( styrene ) at low temperatures with an emulsifier being a
mixture of disproportioned rosin soaps and synthetic fatty acids. The
AO-6 (polyguard) is used as an antioxidant. |
APPLICATION :
The butadiene-alpha-methyl styrene ( styrene ) rubber
finds its use in engineering rubber goods manufacture and in footwear
industry. The butadiene-alpha-methyl styrene ( styrene ) rubber is
similar to those to SBR 1502 |

DESCRIPTION :
The butadiene-alpha-methyl styrene ( styrene ) rubber is
produced by emulsion copolymerization of butadiene and alpha-methyl
styrene ( styrene ) at low temperatures with an emulsifier being a
mixture of soaps, rosin and synthetic fatty acids.BTC-150 and BC-1
mixture is used as an antioxidant. |
APPLICATION :
SKMS-30 ARKM-27 ( SKS – 30 ARKM – 27 ) rubber is
all-purpose. In general it is used in tire industry and in engineering
goods manufacture. The processing properties, synthetic rubber
technology, performance and quantity of ingredients of SKMS-30 ARKM-27 (
SKS-30 ARKM-27 ) are similar to those to SBR 1712. |
