The polyurethane pu insulation board is a rigid foam material, which is made of high-performance resin and foaming agent. It is not only light in weight, but also has low thermal conductivity, aging resistance, and no droplet when burning. It is widely used for heat insulation of roofs, walls, ceilings, doors and windows, etc. In addition, it can also be used for heat insulation of household appliances and equipment.
Polyurethane rigid foam panel is a high molecular polymer, which is made of isocyanate and polyether as the main raw materials, mixed by special equipment under the action of foaming agent, catalyst, flame retardant and other additives, and foamed by high-pressure spraying on site.
