What’s polyurethane sandwich panels?
Polyurethane Foam Sandwich Panel is a specialized material for cold storage insulation and thermal insulation. It is made of rigid closed-cell foam PU (polyurethane) as the core, and the outer skin material is FRP (fiberglass), CFRT, and other skins as the skin, which is laminated by vacuum and high pressure. It usually has a three-layer structure or more. It is a thermal insulation, lightweight, heat insulation, fireproof, and weatherproof material, usually used in reefer body, industrial, residential insulation, and other applications. The thermal stability of PU foam is generally -40℃ to 80℃.
We are manufacturers of polyurethane foam sandwich panels; we use high-quality adhesive to make the skin and core more tightly, preventing de-gluing or bulging. We can provide different sizes, colors, finishes, CNC machining, and so on.
제품 설명:
기능:
Good thermal insulation: the thermal conductivity of PU foam board ranges from 0.020 to 0.025 W/m-K.
Good compression resistance: low-density compression resistance can be 150-500 kPa and high-density up to 600-1000 kPa.
Good durability: acid-resistant, alkali-resistant, aging-resistant, and waterproof.
UV resistance: UV-resistant treatment improves UV weather resistance.
Easy to install: modular production, easy to install, reduces cost.
Lightweight material: 30-50 kg/m³; reduce weight.
Easy processing: can be easily cut and molded, versatile.
