Hard polyurethane foam plastic features include:

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

2. Lightweight, reducing load; excellent waterproof performance, combining thermal insulation and waterproofing into one.

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

4. Fluorine-free foaming, wide environmental adaptability; suitable for thermal insulation and cold preservation in refrigerated trucks, storage tanks, pipelines, cold storage, beer fermentation tanks, and fresh-keeping drums. Also applicable to pre-fabricated polyurethane panels, tube shells, curved panels, and more.

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