The Advantages, Disadvantages and Applications of Polyurethane

Advantages: Better stability, chemical resistance, resilience and mechanical properties, with less compression set. It has good thermal insulation, sound insulation, shock resistance and anti-virus performance.

Disadvantages: Its flame retardant performance is poor, the burning speed is fast, and excessive droplets will be produced in the process, which will easily lead to the accelerated spread of fire.

Application of Polyurethane

Rigid polyurethane plastic is light in weight, excellent in sound insulation and thermal insulation, chemical resistance, good electrical properties, easy processing, and low water absorption. It is mainly used in construction, automobile, aviation industry, thermal insulation structural materials.

The performance of polyurethane elastomer is between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. Mainly used in shoe industry and medical industry. Polyurethane can also be used to make adhesives, coatings, synthetic leather, etc.

Polyurethane appeared in the 1930s. After nearly 80 years of technological development, this material has been widely used in the field of home furnishing, construction, daily necessities, transportation, and home appliances.
