Application and Development of Polyurethane Elastomers

by:DMS Seals     2022-02-09


The comprehensive performance of urethane elastomer is extremely superior. In recent years, countries have been strengthening their application development research according to market demand.







Development focuses on the following aspects:


1. Polyurethane elastomers for automobiles. Today's automotive industry is moving towards high performance, low weight, comfort and safety. Rubber and plastic synthetic materials are gradually replacing metal materials, which opens up extremely broad prospects for the application of polyurethane elastomers. Goodrich Company of the United States has developed the second generation TPU, and its business name is Estaloc. The product maintains the characteristics of the first-generation TPU Estaloc, and uses hollow glass spheres as fillers, which increases the gloss by more than 15%. It can be used to manufacture automobile side panels and shock pads. The installation of airbags on automobiles is the need for the development of the modern automobile industry, and plays an important role in protecting the life safety of drivers. This kind of airbag must have a certain strength to withstand high-speed impact, and also have good low-temperature flexibility. It is suitable to be made of polyurethane. The amount of glue used for each airbag is about 300 grams. Most of the cars in our country have not yet installed airbags, and the market demand is huge. Utilize the high strength and high load-bearing capacity of polyurethane elastomers. It can manufacture tires for medium and low-speed heavy-duty vehicles, with high strength and high bearing capacity, and can manufacture tires for medium and low-speed heavy-duty vehicles. In recent years, a new type of green polyurethane composite tire is being researched and developed. It is based on new and old rubber bare tires, and is poured with a certain thickness of high wear-resistant and puncture-resistant polyurethane rubber surface layer. It is currently in the mileage test. stage, and is expected to be put into production soon.



2. Polyurethane elastomer for construction. The traditional asphalt linoleum waterproof material has been gradually replaced by the durable and integral construction polyurethane waterproof material; only 10 years ago, only the most official competition venues used polyurethane pavement for the runway of the sports field. Secondary schools, and even some primary and secondary schools are also covered with polyurethane plastic runways; expansion joints of large bridges, airport runways and caulking of highways have also begun to use room temperature cured polyurethane elastomers to make sleepers for high-speed railways. ^The ideal material, the sleepers laid on the tunnels and bridges of the Shinkansen railway in Japan are made of polyurethane elastomer. This new application gives full play to the characteristics of polychloric acid elastomers, such as light weight, good shock absorption, and aging resistance, and is very valuable for promotion.






3. Polyester elastomer for mining. Coal mines, metal and non-metal mines are in great demand for non-metallic materials with high wear resistance, high strength and elasticity. In the past 10 years, many coal plants have replaced the cumbersome metal sieve plates with polyurethane elastic screen plates, which not only greatly prolongs the service life of the sieve plates, but also significantly reduces the noise of the operating environment, resulting in obvious energy saving and consumption reduction effects. Others such as cyclone used for solid separation, flame retardant and antistatic wear-resistant conveyor belt, solid core wheel for mining monorail crane, coupling plate for coal mine shotcrete machine, oil sealing ring on 10,000-ton electric wheel dump truck , cold repair glue for high-voltage cable jackets, etc. have also played a huge role in mine construction. There are still many wear-resistant elastic products for mines waiting for us to develop and promote.








4. Polyester elastomer for shoes. Since Taiwanese businessmen came to the mainland one after another, my country's footwear industry has developed rapidly. Polyester elasticity has the advantages of good cushioning performance, light weight, wear resistance, anti-skid, etc. It has become an important supporting material in the shoe industry, golf shoes, baseball shoes, football shoes, ski shoes, travel shoes, safety shoes. The sole, heel, toe, insole and other important accessories of many shoes are made of polyurethane elastomer, which is not only beautiful, but also comfortable and durable, and can improve sports performance.






5. Medical polyurethane elastomer. Good biocompatibility, blood compatibility, and no various additives are important reasons for the application of TPU and CPU materials in the medical field. The medical elastomer products that have been successfully developed so far include: tracheal cannula, prostheses, embolizing agents for family planning, materials for repairing skull defects, condoms, etc., and their application prospects in the medical and health field are still very broad.





6. New type polyurethane composite sheet. The UK is developing a polyurethane composite sheet called the SPS plywood system that will revolutionise the shipbuilding industry. It consists of two layers of 9mm thick steel plates and a 40mm thick polyurethane elastomer injected into them. Once developed successfully, it can replace the traditional reinforced steel plate materials used in shipbuilding. The advantages are: saving manufacturing time, saving steel plates, and reducing the weight of the hull , Impact resistance, fatigue resistance, shock absorption, noise reduction, heat insulation. Once the composite materials of the SPS system are used to build ships in the future, the consumption of polyurethane elastomers in the shipbuilding industry will be an astonishing number.
