The raw material polyurethane composite polyether used in polyurethane insulation board is modified by chemical molecular structure, introducing N.P hetero-ring to change the chain structure of polyurethane, overcome the shortcomings of the traditional flame retardant technology, flame retardant is easy to migrate and PIR foam is easy to secondary foaming, so that the product molecular structure is more stable and durable, and the flame retardant effect is not attenuation. At the same time, the high temperature molding technology is used to make the product structure more stable and reliable.
The product is a polyurethane thermal insulation composite board with rigid foam polyurethane as core material and flexible inorganic coil as surface layer on both sides of continuous production line. The product has low thermal conductivity, high flame retardant performance, good dimensional stability, and is easy to bond with the wall and the finishing layer; Plate adopts numerical control cutting, high dimensional precision; Products according to the application to meet the corresponding fire rating requirements.
Excellent insulation performance
Polyurethane thermal insulation board has the lowest thermal conductivity among organic thermal insulation materials (≤0.022). A class A composite board with A thickness of 5cm is equivalent to the thermal insulation effect of 1m thick concrete.
Super flame retardant property
Polyurethane insulation board can adapt to a wide temperature range, can be used in the environment of -50ºC~150ºC for a long time, and can withstand short-term high temperature of 250ºC, the physical and chemical properties of the foam will not produce any damage.
Excellent weather resistance
Polyurethane insulation board after more than 6 months of weather resistance test, the performance is stable, and the building can be the same life.
Good dimensional stability
The compressive strength of polyurethane insulation board reaches more than 200KP. The board has good temperature resistance and does not deform.
Low carbon and environmental protection
Polyurethane insulation board is made of bio-based raw materials, fluorine-free foaming, no harmful substances prohibited or restricted by the state, green and environmental protection.
