One of the main raw materials of polyurethane insulation materials is rigid polyurethane foam combined with polyether. Polyurethane rigid foam combined polyether is also called white material, and together with polymer MDI it is called black and white material. It is suitable for various occasions requiring thermal insulation, cold room, solar energy, water heaters, cold room, constant temperature storage, beer cans, refrigeration, etc.
Polyurethane foaming refers to the production of polyurethane foam from polyurethane raw materials through a series of reaction processes, called polyurethane foaming.
The raw material for the production of polyurethane foam is rigid polyurethane foam combined with polyether, and the cost is relatively high. Rigid polyurethane foam combined polyether is also acalled white material and, along with polymer MDI, it is called black and white material. It is suitable for various occasions requiring thermal insulation, such as building insulation, solar energy, water heaters, cold storage, constant temperature storage, beer cans, refrigeration, etc.
