Advantages:
It's composed of cross-linked polyolefin and hot melt adhesive double layer, the outer polyolefin is insulating and flame retardant material, the inner layer of hot melt adhesive can buffer mechanical strain and strong sealing, can withstand 125℃ high temperature for a long time, hot melt adhesive does not flow loss, and the double-wall tube will not slide.
