NBR/PUR是一款新型的合金材料，以丁腈膠（NBR）為主體,用PUR改性的合金膠。具有耐低溫（-60℃），耐油、耐臭氧老化、耐磨等特點。因此廣泛應用于膠管內膠、膠帶、汽車異型管等。

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.
