What are the performance characteristics of rigid polyurethane foam materials?

Rigid polyurethane foam materials are tough and have excellent resistance to compression deformation, ensuring long-term stability in gap-filling, gasketing, and sealing applications. Rigid polyurethane foam materials maintain their integrity and effectiveness even when exposed to changing temperatures for extended periods of time. Ideal for applications that may have to deal with extreme environments. This includes all types of applications where heat, vibration, dust, dirt, and shock are present.

• Unique heat insulation and thermal insulation performance, high efficiency of power saving and environmental protection; lightweight, reduce the load.
• With excellent waterproof performance, heat preservation and waterproofing in one.
• Simple design, high efficiency, fast progress, good quality and long life.
• Fluorine-free foam, wide adaptation to the environment.
• Bonding power: strong bonding ability, can be applied in industries such as electronic equipment manufacturers, new energy industry and railroad market. Solid surface bonding.
• Thermal conductivity: can reach 0.017-0.022W/m.k, lower than rock wool, glass wool, polystyrene board, extruded plastic board and other building thermal insulation materials.
• Water repellent performance: water repellent rate of more than 95%.

Polyurethane foam is made by the reaction of rigid polyether polyol and polymerized black material. Rigid polyurethane foam material is widely used in refrigerator, cold storage, spraying, solar energy, thermal pipeline, cell phone, automobile and other fields.

Rigid polyurethane foam is mostly a closed-cell structure, which has excellent characteristics such as good insulation effect, lightweight, high specific strength, easy construction, etc. It also has the characteristics of sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, solvent resistance, etc. It is widely used in electronic equipment manufacturers, the new energy industry, etc. Generally speaking, the lower-density polyurethane rigid foam is mainly used as heat insulation (thermal insulation) material, while the higher-density polyurethane rigid foam can be used as a structural material.

Polyurethane rigid foam is generally room temperature foaming, and the molding process is relatively simple. According to the degree of mechanization of construction, it can be divided into manual foaming and mechanical foaming; according to the pressure of foaming, it can be divided into high-pressure foaming and low-pressure foaming; according to the molding method, it can be divided into pouring foaming and spraying foaming.

The main uses of polyurethane foam are as follows

• For food and other industries' refrigeration equipment: such as refrigerators, freezers, cold storage, and refrigerated trucks, polyurethane foam is the most ideal insulation material for refrigeration equipment.
• Industrial equipment insulation: such as storage tanks, pipelines, etc.
• Transportation industry: such as car canopy, interior parts, etc.
