What are the performance characteristics of rigid polyurethane foam materials

Rigid polyurethane foam material is rigid and has excellent compression set resistance to ensure long-term stability in caulking, gasketing and sealing applications. Rigid polyurethane foam material maintains integrity and effectiveness even after prolonged exposure to changing temperatures. Ideal for use in potentially extreme environments. Various applications including heat, vibration, dust, dirt and vibration.

Features of rigid polyurethane foam:

• Unique thermal insulation performance, high power saving efficiency, environmental protection; light weight, reduce load;

•Excellent waterproof performance, heat preservation and waterproof are combined into one;

• Simple design, high efficiency, fast progress, good quality and long life;

• Fluorine-free foam, adaptable to a wide range of environments;

•Adhesion: strong adhesion, can be used in electronic equipment manufacturers, new energy industry and railway market and other industries. The surface is firmly bonded;

• Thermal conductivity: can reach 0.017-0.022W/m.k, which is lower than building thermal insulation materials such as rock wool, glass wool, polystyrene board, extruded plastic board;

• Hydrophobicity: The hydrophobicity rate is over 95%;

 

Polyurethane foam is made by the reaction of rigid foam polyether polyol and polymeric black material. Rigid polyurethane foam materials are widely used in refrigerators, cold storage, spraying, solar energy, thermal pipelines, mobile phones, automobiles and other fields.

 

What is polyurethane foam material?

Rigid polyurethane foam is mostly closed-cell structure, which has excellent thermal insulation effect, light weight, high specific strength, convenient construction, etc. It also has the characteristics of sound insulation, shock resistance, electrical insulation, heat resistance, cold resistance, solvent resistance, etc. Used in electronic equipment manufacturers, new energy industries, etc. Generally speaking, lower density polyurethane rigid foam is mainly used as thermal insulation (insulation) material, and higher density polyurethane rigid foam can be used as structural material.

 

Polyurethane rigid foam is generally foamed at room temperature, and the molding process is relatively simple. According to the degree of construction mechanization, it can be divided into manual foaming and mechanical foaming; according to the pressure during 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 spray foaming.

 

The main uses of polyurethane foam are as follows

• Refrigeration and refrigeration equipment in food and other industries: such as refrigerators, freezers, cold storage, refrigerated trucks, etc., polyurethane rigid foam is the most ideal thermal insulation material for refrigeration and refrigeration equipment.

•Insulation of industrial equipment: such as storage tanks, pipes, etc.

• Transportation industry: such as car roof, interior parts and so on.
