Properties and Uses
of Polycarbonate Resin
1. Introduction

Polycarbonate resin (Polycarbonate, referred to as PC) is a high-performance engineering plastics, because of its unique properties and a wide range of applications, in the chemical production of raw materials in the field of play an important role. In this paper, the properties, production methods, application fields and development prospects of polycarbonate resin are introduced in detail.

2. The properties of polycarbonate resin

1. Physical properties: Polycarbonate resin has high strength, high rigidity, high transparency, good weather resistance, excellent dimensional stability and other physical properties. Its impact resistance is particularly excellent, commonly known as "not broken glass".
2. Chemical properties: Polycarbonate resin has good chemical resistance and can resist corrosion of acid, alkali, grease and other substances. But at high temperatures, vulnerable to some organic solvents, alkali and metal erosion.
3. Thermal properties: Polycarbonate resin has high heat distortion temperature and heat resistance, and can maintain good mechanical properties in a wide temperature range. Method for Producing

3. Polycarbonate Resin The method for producing

polycarbonate resin mainly includes interfacial polycondensation method and melt transesterification method. Among them, the interfacial polycondensation method is the most commonly used production method, which is produced by the interfacial polycondensation reaction of bisphenol A and phosgene in an alkaline aqueous solution.

4. Polycarbonate Resin Application

1. Electronic products: Polycarbonate resin is widely used in the manufacture of electronic products, such as mobile phones, TVs, computers and other housings and parts, as well as circuit boards, power sockets, etc.
2. Construction industry: Polycarbonate resin can be used to make building materials, such as windows, roofs, wall panels, etc. Because of its high strength, high transparency and good weather resistance, it can improve the service life and energy saving performance of buildings.
3. Automobile industry: Polycarbonate resin is often used in the manufacture of headlamp covers, instrument panels, seat frames, etc. in the automobile industry. Because of its light weight, high strength, and good weather resistance, it can improve the fuel economy and safety of automobiles. Sex.
4. Medical devices: Polycarbonate resin has excellent biocompatibility and high temperature disinfection performance, so it is often used in the manufacture of medical devices, such as infusion sets, syringes, artificial kidneys, etc.

5. development prospects

With the continuous progress of science and technology, the application field of polycarbonate resin will continue to expand. In the future, the development direction of polycarbonate resin will mainly focus on high performance, functionalization, environmental protection and so on. At the same time, with the improvement of people's quality of life and environmental protection requirements, the application of polycarbonate resin in green buildings, new energy vehicles, renewable energy and other fields will be further promoted.

6. conclusion

polycarbonate resin as a kind of high performance engineering plastics, has a wide application prospect in the field of chemical production raw materials. Its unique physical and chemical properties make it play an important role in the fields of electronic products, construction industry, automobile industry, medical equipment and so on. With the continuous development of science and technology, the performance and application of polycarbonate resin will be further expanded and improved.
