DRS(ZRG) and MPG low temperature flame-resist heat-shrinkable tubes are new high-tech products. They have good physical and chemical performance such as corrosion- resistance, insulate and flame-resistance. They are new materials for the power and com munication projects.They apply in the insulate of the cable and terminal and connector, protection and mark, linear components used in the power system, insulated protection of the terminal and connector and handling the conduct wire of the soft cable, As only heat gun can shrink them, they are easily used.
