NBR/PUR是一款新型的合金材料，以丁腈胶（NBR）为主体,用PUR改性的合金胶。具有耐低温（-60℃），耐油、耐臭氧老化、耐磨等特点。因此广泛应用于胶管内胶、胶带、汽车异型管等。

NBR / pur is a new type of alloy material, which is based on nitrile butadiene rubber (NBR) and modified by pur. It has the characteristics of low temperature resistance (- 60 ℃), oil resistance, ozone aging resistance and wear resistance. Therefore, it is widely used in rubber hose inner glue, adhesive tape, automobile special-shaped pipe and so on.
