SIBUR Synthetic Rubber NBR 3335
Описание материалов:
NBR 3330, NBR 3335 are essentially an acrylonitrile (31-35 %) and 1,3-butadiene copolymer obtained by emulsion polymerization method at a temperature with the use of fatty acid soaps as emulsifier in accordance with the ecologically clean technology. Medium content of acrylonitrile, heightened oil resistance.
Product characteristics: Appearance - bales of light-yellow to pink or light-beige color depending on used antioxidant; weight of a bale - (30 ± 1) kg; packing - a plastic container 540 or 450 kg; shelf life - one (1) year since the date of manufacture.
