Polybutadiene Rubber (PBR) SKD-Nd

 ► Synthetic polybutadiene rubber SKD-Nd is a product of polymerization of butadiene in solution in the presence of rare-earth metal-base neodym compounds as catalyst with addition of an antioxidant, which contains at least 96% of 1,4-cis-bonds. The polymer contains no nitrosamines or substances that may be a source of nitrosamines.

► Product characteristics: Appearance – bale of white to light-yellow color; weight of a bale - (30 ± 1) kg; packing – a metal container, a plastic container; shelf life – one (1) year since the date of manufacture.
