This heat shrink protective tube is made of radiation crosslinked polyolefin, during which the heating & expansion technique has been employed. It starts shrinking when the environmental temperature reaches 90 ℃ and completes shrinking when the temperature reaches 130℃. The heat shrink tube can be used to protect low-to-medium voltage cables and cable joints from water. To deliver even better sealing performance, hot-melt adhesives are smeared inside the tube. Two smearing methods are available, one with the adhesives smeared on both ends, and the other with the adhesives smeared along the wall.
