Rigid 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 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 insulation and heat preservation of refrigerated trucks, storage tanks, pipelines, cold storage, beer fermentation tanks, and fresh-keeping drums. Also applicable to prefabricated polyurethane boards, tube shells, arched plates, etc.

One of the main raw materials for polyurethane thermal insulation materials is polyether polyol for rigid foam. Polyether polyol for rigid foam is also known as the "white material," commonly referred to as the "black and white materials." It is suitable for various applications requiring thermal insulation and cooling, such as building insulation, cooling, solar energy, water heaters, cold storage, constant-temperature storage, beer kegs, and refrigeration.
