55 density polyurethane

Product Introduction:

Rigid polyurethane (PU/PUR) foam board is a closed-cell polymer material produced by the addition reaction of isocyanate and polyol. Its stable molecular structure makes it one of the best-performing industrial insulation materials currently available.

The product features a fully closed-cell structure, combining multiple advantages such as ultra-efficient thermal insulation, lightweight yet high strength, moisture resistance, corrosion resistance, and dimensional stability. It also boasts good sound insulation, impact resistance, and electrical insulation properties. Customized flame-retardant formulations are available, making it widely applicable in insulation applications for refrigerated trucks, cold storage facilities, containers, RVs, and building walls.

PRODUCT DESCRIPTION

Product Core Features

• Ultra-efficient thermal insulation: Thermal conductivity as low as 0.017 W/(m・K), its insulation performance far surpasses traditional materials, significantly reducing energy consumption.

• Closed-cell moisture-proof: Closed-cell rate ≥97%, water absorption rate ≤0.2%, no water absorption, no mold growth, and no aging even after long-term use.

• Lightweight and high-strength: Multiple density options available, balancing insulation performance and structural strength to suit various application scenarios.

• Dimensionally stable: No expansion or contraction, resistant to high and low temperature changes, no deformation or cracking even after long-term use.

• Strong adhesion: Strongly bonds to surface materials such as FRP, aluminum plates, and color steel plates, suitable for various sandwich panel structures.

• Processing-friendly: Supports manual/mechanical cutting and CNC forming; specifications and shapes can be customized as needed.
