Polyurethane rigid foam
Polyurethane rigid foam is a high molecular polymer made of isocyanate and polyether as main raw materials, mixed by special equipment and foamed on site by high-pressure spraying under the action of blowing agent, catalyst, flame retardant and other additives. There are two kinds of polyurethane foam: soft foam and hard foam. The soft bubble has an open cell structure and the hard bubble has a closed cell structure; Soft bubbles can be divided into skinned and non skinned.

The main function of polyurethane soft foam is cushioning. Polyurethane soft foam is commonly used in sofa furniture, pillows, cushions, toys, clothing and sound insulation lining.
Polyurethane rigid foam is a new type of synthetic material with thermal insulation and waterproof functions. Its thermal conductivity is low, only 0.022-0.033w / (m)* Κ）， It is equivalent to half of the extruded plate and has the lowest thermal conductivity among all insulation materials. Rigid polyurethane foam is mainly used in building exterior wall insulation, roof waterproof and insulation integration, cold storage insulation, pipe insulation materials, building panels, refrigerated vehicles and cold storage insulation materials.
1. High efficiency and energy saving, no gap after filling, and strong bonding after curing.
2. Shockproof and compression resistant, no cracking, corrosion and falling off after curing.
3. It has ultra-low temperature thermal conductivity, heat resistance and insulation.
4. High efficiency insulation, sound insulation, waterproof and moisture-proof after curing.
5. This joint sealant can be adhered to concrete, coating, wall, wood and plastic surfaces.
