In 2024, the production of major household appliances will steadily increase: refrigerators, air conditioners, washing machines, and televisions will have year-on-year growth rates of 8.3%, 9.7%, 8.8%, and 4.6%, respectively.
Driven by consumer upgrading, trade in policies, and the development of smart homes, the demand for high-performance modified plastics (such as flame-retardant, weather resistant, and environmentally friendly materials) in the home appliance industry is continuously increasing.
Other engineering fields
In addition to automobiles and home appliances, modified plastics are also constantly expanding in multiple high growth fields such as rail transit, aerospace, health protection (food packaging and medical), and home building materials.
With the promotion of intelligent manufacturing, energy conservation and environmental protection, and the upgrading of emerging industries by the country, the application boundaries of modified plastics continue to expand, and their performance continues to improve, bringing broad space for the development of the industry.
4. Technological Development: Innovation drives material performance improvement
Modified plastic technology is developing towards high performance, functionality, and environmental friendliness. The application of new modification technologies such as multiple modification and interface modification is achieving a leap in material performance, meeting the needs of more extreme environments and special properties.
In terms of environmental protection, the research and development of bio based modified plastics and biodegradable modified plastics will reduce dependence on fossil resources and respond to the call for global sustainable development. In addition, intelligent modified plastics, such as materials with self sensing and self-healing functions, will be the forefront direction of materials science in the future.
Nanjing Kelongweier Chemical Machinery Co., Ltd., as a professional enterprise engaged in the manufacturing of plastic polymer blending and modification equipment, has expanded the application scope of twin-screw extruders through research, development, and improvement, providing important equipment support for the process technology of degrading plastics, modifying plastics, and modifying blended plastics.
5. Future prospects: Green and low-carbon bring new opportunities
With the deepening of the "dual carbon" strategy and the increasing demand for lightweight and high-performance in various industries, the modified plastics industry is expected to usher in broader development opportunities. Environmental pressure and policy support will continue to promote the replacement of traditional materials with modified plastics.
In the coming years, the application of modified plastics in fields such as new energy vehicles, smart devices, and environmentally friendly materials will become more widespread. Especially in the new energy vehicle industry, the trend towards lightweighting will continue to drive the demand for high-performance engineering plastics.
It is predicted that high-performance engineering plastics such as modified nylon will continue to maintain a rapid growth trend, with an expected compound annual growth rate of over 13%. By 2030, the modified plastics industry will form a more complete technological innovation system and industrial chain layout.
