1. Types of polyurethane wall panels
For the building applications, polyurethane panels can be classified into ordinary polyurethane panels and polyurethane sandwich panels according to the condition of the products; they can be divided into continuous panel production lines and discontinuous production lines according to the foam molding process. Intermittent panel material requires the foaming material to be filled with a thin and large volume cavity in a relatively short period of time, requiring excellent fluidity of the foaming system, good density distribution of the panel and excellent dimensional stability; continuous panel The foaming parameters are required to have suitable compatibility with the production line speed, and have excellent mold release properties in the later stage. In response to the above specific requirements, we have developed a foaming material system suitable for various production lines using special polyether materials and a suitable catalytic system, which are used in some well-known domestic production line .

2.Advantage:
1. Polyurethane has a multipurpose function, at the same time, it has insulation, waterproof, sound insulation, vibration and many other features.
2. The excellent insulation properties of polyurethane, it is currently the lowest thermal conductivity(≤ 0.024) of all building materials, the highest thermal resistance of the insulation material, thermal conductivity is only a half of EPS foam polystyrene board.
3.Polyurethane continuous dense skin and nearly 100% high-strength interconnection wall, with the ideal impermeability. The use of spraying method to achieve waterproof insulation layer continuous seamless, the formation of seamless roof and the overall external wall insulation shell, the waterproof and impermeable performance is excellent.
4. Polyurethane has super self-adhesive performance (without any intermediate bonding material), anti-wind and anti-negative wind pressure performance is good; the overall spraying construction, completely eliminate the "hot section" and "cold bridge", flexible gradient technology can effectively prevent the waterproof layer cracking; mechanized operations, automatic ingredients, uniform quality, fast construction, short cycle.
