Characteristics: 1) Light, easy to be processed and installed 2) Waterproof, impermeable, heat insulation, shockproof, sound absorption and noise reduction 3) Heat-resisting, cold-resisting, chemical-resisting, aging-resisting 4) Insulate any heat media with a stable and low coefficient of heat conduction 5) Generate no pollutant bringing harm to people's health when being installed and in use. Usage: 1) Roof, wall and floor 2) Shell of air-condition, water heater, high temperature furnace 3) Protective coating of water pipe and ventilating pipe 4) Heat insulation, sound absorption and noise reduction for refrigerator car and laboratory 5) Packing for special products and cold storage We combine aluminum foil with XPE. It is an environmentally friendly product with ability in heat preservation, insulation and barrier of moisture, fire and sound. Compared with EPE, XPE has stronger strength of extension and smaller bubble. It is an ideal material for heat preservation of automobile and air-condition. These years, XPE is widely used in market of sports relaxation, such as surfboard, moisture proof mat, shoe material and yoga mat. It also applies to architecture like insulation floor.
