以丁腈橡胶/聚氯乙烯(NBR/PVC)并用胶为主要原材料,研制了密度低于90kg/m3的闭孔低密度挤出海绵条,同时加入适当的阻燃剂,使之垂直燃烧性能等级达到FV-0级。
With NBR / PVC (polyvinyl chloride) (NBR / PVC) as the main raw material, a closed-cell low-density extruded sponge with a density of less than 90kg / m3 was developed, and proper flame retardants were added to make the vertical burning performance Level reached FV-0 level.
