After decades of development, polyurethane materials have covered all aspects of production and life, but there is still broad room for development in the future.
1. Rigid foam is the largest single application form of polyurethane materials.
In the field of exterior wall building insulation materials, rigid polyurethane foam accounts for 7% in my country, compared with 65% in the United States. There is still a lot of room for improvement.
Moreover, the rapid development of cold chain logistics in my country will bring greater demand for hard foam.
2. Due to its strong comfort, polyurethane soft foam is suitable for sports equipment such as yoga mats and boxing gloves, which is in line with the consumption upgrade and comprehensive fitness development trend of my country's clothing industry.
3. Composite high-density polyether polyurethane materials can be used to prepare materials with memory functions. They have viscoelastic properties and can automatically change shape as the head and neck position changes. In addition, they can be used in human body mechanics. It absorbs impact force and has functions such as memory deformation and automatic shaping.
4. Polyurethane can be used to make track bed curing materials, which can give full play to the advantages of polyurethane materials such as good elasticity, stability, and wear resistance, and solve the technical problems of difficult maintenance and repair of ballasted track bridges and tunnels. At the same time, it has good vibration reduction The noise reduction function provides a suitable track structure form for urban rail transit.
5. The plastic track is composed of polyurethane elastomer and other materials. It has a certain degree of elasticity and can be colored. The polyurethane plastic playground has advantages that ordinary playgrounds cannot match. It is internationally recognized as the best all-weather outdoor sports ground material. With the continuous development of my country's economy and society, the country has also increased its investment in culture and education. It can be expected that the plastic track industry will maintain sustained development momentum.
