Engineering plastics is a kind of high-performance materials, mainly used in the manufacturing process in the industrial field. With the continuous development of science and technology, people's requirements for materials are getting higher and higher, and engineering plastics are emerging to meet this demand. Compared with traditional plastics, engineering plastics have more excellent characteristics, they can withstand high temperatures, corrosion resistance, high strength and excellent wear resistance. These characteristics make engineering plastics widely used in various fields of modern industry. There are many types of

engineering plastics, such as polyimide (PAI), bonded polyamide (PEEK), polyether amide (PEI), polyamide (PA), polymethyl methacrylate (PMMA) and so on. These plastics have their own unique characteristics and application areas, the following is a brief introduction of several common engineering plastics.

polyimide (PAI) is a kind of engineering plastic with high strength, high stiffness and high temperature resistance (above 200 ℃), which has excellent electrical properties and chemical stability. It is mainly used in the manufacture of aircraft and spacecraft, high temperature electrical equipment, environmental protection equipment and other fields.

bonded polyamide (PEEK) is also a high-performance engineering plastic, with very high temperature resistance (can withstand temperatures up to 316°C), high strength, excellent corrosion resistance and wear resistance. It is mainly used in aerospace, automotive, medical equipment and other fields.

polyether amide (PEI) is a high-performance plastic with excellent mechanical properties, UV resistance, corrosion resistance and high temperature resistance. It is mainly used in electronic and power equipment, food processing, chemical processing and other fields.

In addition to the above-mentioned engineering plastics, there are many other types of engineering plastics, each of which has unique characteristics and uses. In general, engineering plastics have the following characteristics:

1. High strength and high rigidity: Engineering plastics have excellent mechanical properties, can withstand high strength, and have high rigidity.

2. Good temperature resistance: Engineering plastics have very good temperature resistance and can withstand high temperature or even ultra-high temperature environments, so they are widely used in high temperature fields.

3. Good corrosion resistance: Engineering plastics have very good corrosion resistance and can withstand the erosion of various corrosive substances.

4. Lightweight and easy to process: Engineering plastics are light and easy to process, so they can greatly save energy and time in the manufacturing process.

In general, engineering plastics has become an indispensable material in modern industry, and its application fields are very wide, including aerospace, automotive, medical equipment, electronic equipment, home appliances, environmental protection and so on. With the continuous improvement of material performance requirements, engineering plastics will have a broader application prospects.
