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.

  • PU composite sandwich panel is a high-quality thermal insulation material.
  • Lightweight material for easy installation and handling.
  • Good durability and long service life.

자주 묻는 질문

Polyurethane sandwich panels are usually sandwich panels. They have two skins, with polyurethane foam as the core. The skin protects the sandwich layer. The PU has great insulation and durability. It’s widely used in refrigerated trucks, RVs, and other insulated places.

There is a big difference between PU sandwich panels and PIR sandwich panels.

The core material of the PU sandwich panel is PU foam, and the core material of the PIR sandwich panel is PIR.

PU has excellent thermal insulation performance; however, PIR has better fireproof performance.

In terms of cost, PU is much more affordable than PIR.

Polyurethane insulation is the use of polyurethane foam as an insulating material. Polyurethane insulation has several advantages:

  • High insulation performance, which reduces heat transfer and helps to keep the temperature stable.
  • Soundproofing properties.
  • Lightweight.
  • 내구성이 우수합니다.
