Polyurethane elastomers are widely used and diversified development momentum is on the rise-UV absorber manufacturer

Since the transition from military use to civilian use in the early 1980s, polyurethane elastomers have become more and more widely used, with increasing product varieties and grades, and increasing production scale. , the momentum of diversified development is booming, and it plays an important role in the national economy and social production and life.

Polyurethane elastomer is a typical multi-block copolymer with excellent properties, such as high elasticity, high hardness, high strength, good wear resistance, low temperature resistance, and Flexing and so on. Not only that, polyurethane elastomer is also an ideal material for green tires and green tire manufacturing.

According to the “China Polyurethane Elastomer Industry Market Demand Forecast and Investment Strategic Planning Analysis Report” released by the agency, the performance of polyurethane elastomers is mainly realized in a wide hardness range, high performance It has five aspects: large adjustable range, superior wear resistance and various processing methods.

Although polyurethane elastomer has strong performance, it also has shortcomings. The main shortcomings are large endogenous heat, average high temperature resistance, and not resistant to strong extremes. Sexual solvents and strong acid and alkali media. In addition, at room temperature, alcohols, acids, and ketones will cause polyurethane elastomers to swell and degrade, and solvents such as chloroform and dichloromethane will cause polyurethane elastomers to swell.

However, despite its shortcomings, polyurethane elastomer is still a polymer material with excellent performance and can be used in a wide range of applications. Common products include cast polyurethane elastomers, polyurethane elastomers for construction, polyurethane elastomers for machinery manufacturing, medical polyurethane elastomers, polyurethane rubber rollers, etc.

For example, polyurethane elastomer for construction has given full play to the characteristics of polychloric acid elastomer such as light weight, good shock absorption, and aging resistance. It has been promoted on the sleepers of high-speed railways, and has also Gradually replacing the traditional asphalt linoleum waterproofing material.

For another example, polyurethane elastomer occupies an important position in medical polymer materials due to its high strength, wear resistance, biocompatibility, and no plasticizer. , has successfully developed tracheal cannulas, plugging agents, etc.

Generally speaking, polyurethane elastomers have broad application prospects, and global consumption is growing rapidly year by year. It is expected that in the next few years, global polyurethane elastomer consumption growth will remain at around 7-8%. Among them, the automobile industry and the shoemaking industry will be the main consumer markets and the two fastest growing areas.

my country’s demand for polyurethane elastomers is also increasing year by year, but some key raw materials are still dependent on imports, which is not conducive to the further development of the polyurethane industry. In the future, we must accelerate the localization of key raw materials to produce raw materials with excellent performance and low prices.

In summary, with the advancement of new technologies and the promotion of new materials, the application scope of polyurethane elastomers will continue to expand, and there is huge room for future development and promising prospects.
