XR-H 雙壁熱縮套管(XR-H Dall HEAT SHRINKABLE TUBES)
描述:
※ 雙壁熱收縮套管內(nèi)層附有熱熔膠的半柔性熱縮管,外層是由輻射交聯(lián)聚烯烴組成,內(nèi)層是專門設(shè)計的膠性內(nèi)壁;加熱時內(nèi)壁熔融,并隨外壁收縮填充孔隙或縫隙,冷卻后,雙壁管壁厚均勻,結(jié)實.
※ 阻燃級別: UL224 VW-1
※ 產(chǎn)品具有低溫收縮、柔軟、阻燃、防水防潮、耐油耐酸等優(yōu)點.
※ 產(chǎn)品收縮比率:2:1 3:1 4:1
用途:
本產(chǎn)品廣泛應(yīng)用于電子設(shè)備的接線防水,電線分支處的密封固定,金屬管線的防腐保護(hù),以及防止由高分子鏈松弛產(chǎn)生的松動和脫落,如水下燈飾,汽車剎車油管,高級線束的防腐保護(hù).
