SIBUR Synthetic Rubber SSBR-2560 Grade B

About
Butadiene-styrene synthetic statistical rubber with increased content of 1,2-bonds and 1,4 trans-bonds no less 14% of SSBR-2560 is essentially a polymerization product of 1,3-butdiene with styrene in hydrocarbon solvent in the presence of anionic initiating agent, and it is filled with staining antioxidant. The polymer contains no nitrosamines and substances that may become a source of nitrosamines. Product characteristics: Appearance – bale of dark-brown color; weight of a bale – (30 ± 1) kg; packing – a corrugated board container, a plastic container; shelf life – one (1) year since the date of manufacture&&
