Hot melt tube is also known as hose, hot melt glue hose, heating hose. The inner liner of the hot melt hose adopts imported Teflon tube, which has good flexibility, anti-sticking property and high temperature resistance (up to 250 degrees), which can greatly reduce the carbonization phenomenon; the heating part adopts heating wire and high temperature wire, uniform The ground is wound on the outer wall of the throat pipe, which has good insulation, uniform heat conduction and high temperature resistance. The use of high-quality thermal insulation materials ensures the thermal insulation performance of the throat pipe.
