Hard polyurethane foam plastic features include:

1. Unique thermal insulation properties, high energy-saving efficiency, and environmental friendly

2. Lightweight design reduces load; boasts excellent waterproofing, combining insulation and waterproofing into one.

3. Simple design, high efficiency, quick progress, good quality, and long lifespan

4. Fluorine-free foaming, broad environmental adaptability; suitable for thermal insulation and cold preservation of refrigerated trucks, storage tanks, pipelines, cold storage, beer fermentation tanks, and preservation barrels. Also applicable to pre-fabricated polyurethane panels, pipe shells, curved plates, etc.

One of the main raw materials for polyurethane thermal insulation materials is polyether polyol for rigid foam. Also known as the "white material," it is collectively referred to as the "black and white materials." Suitable for various applications requiring thermal insulation and cooling, such as building insulation, cooling, solar energy, water heaters, cold storage, temperature-controlled storage, beer tanks, and refrigeration.
