What are the main polyurethane casting products?

Polyurethane casting products include the following categories in addition to the industrial parts, automotive parts, sporting goods, and medical supplies mentioned above:
Construction field
Sealing materials: such as polyurethane sealant, which is used for sealing building doors, windows, curtain walls, pipe interfaces, etc. It has good weather resistance, water resistance and adhesive properties, and can effectively prevent rain and air infiltration.
Thermal insulation materials: Polyurethane rigid foam is a highly efficient thermal insulation material, which can be made into plates by casting process or sprayed on the surface of buildings, and is used for thermal insulation of walls, roofs, cold storage, etc. It can reduce energy consumption and improve the energy-saving effect of buildings.
Waterproof material: polyurethane waterproof coating can form a continuous and seamless waterproof coating on the roof, basement, bathroom and other parts of the building, with excellent waterproofing performance, which can adapt to different shapes and complex grass-roots surfaces.
Electrical and electronic field
Potting Adhesive: Used for the potting of electronic components, such as power modules, transformers, sensors, etc. It can protect the components from the external environment, such as moisture, dust, vibration, etc., and improve the stability and reliability of electronic equipment.
Insulating components: like insulating gaskets, insulating sleeves, etc. Utilizing the insulating properties of polyurethane, it can prevent leakage and short-circuit phenomena in electrical equipment, and guarantee the safe operation of the equipment.
Packaging
Cushioning packaging materials: like polyurethane foam cushioning pads, cushioning blocks, etc., can be used to package fragile items such as electronic products, glass products, precision instruments, etc., which can effectively absorb and disperse impacts, and protect the items from damage during transportation and storage.
Customized Packaging Containers: According to the shape and size of the products, polyurethane packaging containers are made by casting process, such as the boxes for cell phones, cosmetics, etc., which have good protection and aesthetics.
