What are the industrial applications of polyurethane materials?

2019-07-05

PU soft foam Flexible PU. 

Cushion material-such as seat, sofa, mattress, etc., soft foam seat high-pressure foaming machine polyurethane soft foam is a very ideal cushion material, cushion is also a large amount of soft foam application field; 

Sound absorbing material-perforated polyurethane soft foam has good sound absorption and damping function, and can be used as indoor sound insulation material. 

Fabric composites-shoulder pads, bra sponges, cosmetic cotton; toys. 

PU hard bubble Rigid PU. 

Refrigeration equipment-such as refrigerators, freezers, cold storage, refrigerated vehicles, polyurethane rigid foam is the most ideal insulation material for refrigeration equipment; 

Industrial equipment insulation-such as storage tanks, pipelines, etc.; 

Building materials-in developed countries in Europe and the United States, polyurethane rigid foam for construction accounts for about 70% of the total consumption of rigid foam, which is more than double the amount of hard foam such as refrigerators and freezers. 

In China, the application of hard foam of foaming machine in construction industry is not as common as that of western developed countries, so it has great potential for development. 

Transportation industry-such as car roof, interior accessories (steering wheel, dashboard), etc.; 

Imitation wood-high density (density 300~700kg/m3) polyurethane rigid foam or glass fiber reinforced rigid foam is a structural foam, also known as wood imitation. 

It has the characteristics of high strength, good toughness, dense and tough crust, simple molding process and high production efficiency. Its strength is higher than that of natural wood and its density is lower than that of natural wood. It can be used as a substitute for wood as all kinds of high-grade products. 

Sealing materials-such as waterproof grouting materials, leak plugging materials, roof waterproof materials. 

Flower industry-PU flowerpot, flower mud, etc. 

PU semi-hard bubble Semi-rigid PU. 

Energy absorption foam-energy absorption foam has excellent shock absorption, cushioning performance, good compression load resistance and deformation recovery performance, and its most typical application is to prepare automobile bumper. 

Self-skinning foam (Integral Skin Foam)-used for the preparation of automobile steering wheel, handrail, headrest and other softened internal functional parts and interior accessories. 

Self-skinning foam products are usually processed by reaction injection molding (Reaction Injection Moulding, for short RIM). 

The most typical application of microporous elastomer-polyurethane microporous elastomer is used in shoe industry. 

Polyurethane elastomer (PU Elastomers). 

Castable polyurethane elastomer (CPU) is one of the most widely used polyurethane elastomers. 

Thermoplastic polyurethane elastomer (TPU)-thermoplastic polyurethane elastomer accounts for about 25% of the total polyurethane elastomer. 

Mixed polyurethane elastomer (MPU)-accounts for about 10% of the total polyurethane elastomer. 

Solid tire; printing, conveying cots; pressing cots; oil seal, washer ball section, bushing bearing; O-ring; cushion; sole, rear root, bag head; lining; gear, etc., different application fields, the hardness range of the selected elastomer is different. 

Application in Mining, Metallurgical and other Industries-sieve Plate, shaking bed, etc. 

Application in mechanical industry-cots, tape, seals, etc. 

Application in automobile industry-tire, sealing ring, etc. 

Application in light industry-polyurethane shoe sole, polyurethane synthetic leather, polyurethane fiber; 

Applications in the construction industry-waterproof materials, paving materials, sealing materials and so on.
