PU Outstanding performance 1.High thermal insulation effect There are numerous blast holes insidethe rigidPUfoam. They are interconnected and uniformly distributed to absorbor block sound. So thereis a verygoodsound isolation, which can provide quietand comfortableindoor environment. 2.Great bonding strength The rigid PU foam has excellentbindingforce. It can bond well with cement, steel material, clay, pitch, wood, glass, plastic and other materials. The bonding strength is greater than the crack-resistant strength itself, which is in accordance with Chinese technology requirements for exterior wallthermal insulationprojects. 3.Largecompression The rigid PU foam has gooddimensional stability. Itsdeformationresistantcapabilityis excellent and can not crack especially under the outside force, temperature, moisture, dryness and other negative factors. This helps to ensure the whole stability and durability. 4.Good weathering resistance and long service life Materialized rigid PU foam can be used for 30 years under 130 normally, and can reach 70years under 50.
