Polycarbonate (Polycarbonate, PC) is a polymer compound with excellent physical and mechanical properties, so it has a wide range of applications in the field of chemical production raw materials. This article will detail the properties and uses of polycarbonate.

1. properties of polycarbonate

1. physical properties
polycarbonate is a transparent, amorphous thermoplastic engineering plastics, with high hardness and stiffness, as well as excellent dimensional stability. Its density is usually between 1.2-1.3g/cm³ and its glass transition temperature (Tg) is between 140-150°C.

2. mechanical properties
polycarbonate has high strength, high toughness, impact resistance and other characteristics, its tensile strength and impact strength are high, can maintain good mechanical properties in a wide temperature range.

3. Thermal Properties
Polycarbonate has high heat distortion temperature and thermal stability, can be used at high temperatures, and has good cold resistance.

4. Electrical properties
polycarbonate has excellent insulation properties and can be used in electrical and electronic fields.

5. chemical properties
polycarbonate has good chemical resistance, can resist the erosion of many acids, alkalis and organic solvents.

2. the use of polycarbonate

1.
of building materials Because polycarbonate has the advantages of high strength, high transparency, light and easy processing, it is widely used in the field of building materials, such as glass windows, roofs, wallboards, etc.

2.
of electronic products Polycarbonate has excellent electrical properties and heat resistance, so it is widely used in the field of electronic products, such as circuit boards, electrical housings, battery covers, etc.

3. Auto parts
Polycarbonate has the advantages of high strength, impact resistance, heat resistance, etc., so it is widely used in the field of auto parts, such as car lampshades, windows, seat backs, etc.

4. Medical device
Polycarbonate has the advantages of high transparency, easy processing, chemical resistance, etc., so it is widely used in the field of medical devices, such as medical device shells, infusion tubes, etc.

5. packaging materials
polycarbonate has good chemical resistance and mechanical properties, so it is widely used in the field of packaging materials, such as food packaging containers, cosmetic packaging bottles and so on.

In short, polycarbonate, as an excellent raw material for chemical production, has been widely used in various fields.
