The inner liner is made of imported PTFE tubing, which has good flexibility, anti adhesion, and high temperature resistance (up to 250 degrees), greatly reducing carbonization. The heater adopts imported heating wire and high temperature resistant wire, which are evenly wrapped around the outer wall of the throat and have good insulation and high temperature resistance performance. Using high-quality insulation materials to ensure the insulation performance of the throat and the fluidity of the adhesive. Good bending performance and bending resistance, relying on high-quality materials (continuously bending heating wires and high-temperature resistant wires) and reasonable processing technology design, its maximum bending radius can reach 25cm. Imported K-type temperature sensor can accurately detect temperature and control accuracy within plus or minus 1 degree. The regular 8mm inner liner has a power of 120w/meter, while the 13mm inner liner has a power of 160w/meter. We can customize different types of hot melt hoses and replace domestic and foreign brands of hot melt hoses according to customer requirements.
