Technical Parameters

PU sandwich panel (rigid polyurethane sandwich panel), also known as polyurethane sandwich panel, polyurethane composite panel, polyurethane energy saving panel.

Our company has an advanced continuous production line of PU sandwich panel. The process is formed by cold bending of inner and outer galvanized (aluminized zinc) color steel plates, and polyurethane rigid foam coating in the middle. The patented anti-leakage sandwich roof panel gives full play to the advantages of polyurethane sandwich panel.

Features

PU sandwich panel has beautiful appearance and good overall effect. It integrates load bearing, thermal insulation, fire protection and waterproof functions, and requires no secondary decoration. It is fast and convenient to install, short in construction period, good in comprehensive benefits, and has good cost performance. It is a kind of energy-efficient building enclosure material with wide use and great potential, and is also a new type of energy-saving panel advocated and promoted by the Ministry of Construction.

1. Low thermal conductivity. The polyurethane sandwich panel composite panel has a small thermal conductivity and good thermal insulation performance. It is currently the best thermal insulation material.

2. Beautiful plate shape and easy installation.

3. Polyurethane sandwich panel has good fire resistance.

4. Polyurethane sandwich panel is non-toxic and odorless.

5. Wide operating temperature range

Waterproof, moisture-proof.

Application Scenario

1. PU sandwich panels are bi-metallic, single-metallic, and non-metallic composite panels with polyurethane hard foam as the insulation layer. They are usually used in wall and roof enclosure systems of industrial plants, logistics warehousing, and integrated houses.

2. PU sandwich panel can also be applied to the roofs and walls of various buildings such as large industrial plants, warehouses, exhibition halls, gymnasiums, cold storage, purification workshops, etc. It integrates heat preservation, heat insulation, load-bearing, and waterproofing. It also has the characteristics of rich colors and beautiful appearance.

3. In addition, it can be used for thermal insulation and decoration in ships, vehicles and other fields.
