EXCELLENT HEAT PRESERVATION INSULATION: The high-density and closed structure of the selected raw material has the ability of low thermal conductivity and stable temperature, and has the effect of insulating hot and cold medium, so that the inside of the pipe d Water won't be affected even if the weather is freezing outside CLEAN APPEARANCE OF OUTER TUBE: The insulation material has a smooth surface with high elasticity, soft texture and better anti-resonance effect. In addition, it can also maintain a high-quality appearance even if it is not a ceiling ECO-FRIENDLY MATERIAL: Environmentally friendly raw material has no stimulation and pollution, no harm to health and the environment. In addition, it can prevent mold growth and mouse bites; The material has the effect of resisting corrosion, acid and alkali, it can increase the service life of use GOOD FIRE RETARDANT PROPERTIES: When burned by fire, the insulation material does not melt and leads to low consumption and does not spread the flame, which can ensure the safety of use; the material is determined as non-flammable material and the operating temperature range is -50 to 110 EASY TO INSTALL, EASY TO USE: It is convenient to install because there is no need to install another auxiliary layer, and it only needs to be cut and conglutinated. It will greatly save manual labor.
