Advantages Of Polyurethane Sandwich Panels

‌Polyurethane sandwich panels have the following main advantages‌:

‌Excellent thermal insulation performance‌: The thermal conductivity of polyurethane sandwich panels is low, usually between 0.018-0.024 W/(m·k), which is one of the lowest thermal conductivity among all insulation materials‌. Its closed-cell rate is high, reaching more than 90%, which can effectively isolate air and moisture, further enhancing its thermal insulation effect‌.

‌Good waterproof and moisture-proof performance‌: Polyurethane sandwich panels have excellent waterproof and moisture-proof performance, and the closed-cell structure will not increase the thermal conductivity due to moisture absorption, nor will it leak water‌.

‌Excellent fireproof performance‌: After adding flame retardants, polyurethane sandwich panels have the characteristics of flame retardancy and self-extinguishing, the softening point can reach more than 250 degrees Celsius, and carbon deposits will form on the surface during combustion, effectively isolating the flame‌.

‌High strength and durability‌: Polyurethane sandwich panels have high compressive strength, bonding strength is not less than 0.09MPa, combustion performance reaches B1 level, and bending bearing capacity is strong‌. Its service life is more than 30 years, with good anti-deformation ability and finishing stability.

‌Environmental performance‌: Polyurethane sandwich panels use fluorine-free foaming agents, which are environmentally friendly and will not damage the ozone layer.

‌Wide application areas‌: Polyurethane sandwich panels are widely used in wall and roof enclosure systems of industrial plants, logistics warehouses and integrated houses, and are also suitable for public buildings, modular houses, stadiums and other places. Its surface is easy to clean and has few seams, which is suitable for production environments that require high cleanliness.
