I produced a dedicated electric hot melt polyurethane insulation sleeve, a product change from the previous traditional process, on a dedicated PE sheet, with a special hot melt integrated device, the special nickel-chromium alloy mesh with hot melt compounding, molding together. Because PE sheet of high quality raw materials, and the ratio of certain EVA hot melt adhesive, using co-extrusion equipment, the composite nose raw Mixing and production, and corona treated, it can overflow during welding melt a little jelly around material, plus Nichrome fine texture, arrangement uniform, high calorific value per unit of time, can be more perfect and PE pipeline integration, confined obvious effect, to achieve good welding results. ? Uses: mainly used in anti-corrosion pipe insulation, heat pipe coupling interface. ? Features: good sealing performance, corrosion resistance, long life, easy to use.
