Polycarbonate is a high molecular weight polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five major engineering plastics.



What is PC

Polycarbonate (PC) plastic is a naturally transparent amorphous thermoplastic. Although they are available on the market in various colors, the raw materials allow the internal light transmission to have almost the same capacity as glass. Polycarbonate polymers are used to produce a variety of materials and are particularly useful when impact resistance and/or transparency are required for products.


 PCs are commonly used for plastic lenses in glasses, medical equipment, automotive parts, protective equipment, greenhouses, digital disks (CD, DVD and Blu-ray), and external lighting equipment. Polycarbonate also has very good heat resistance and can be used in combination with flame-retardant materials without significant material degradation. Polycarbonate plastics are engineering plastics because they are often used for stronger, more powerful materials, such as impact-resistant "glass-like" surfaces.



Features of polycarbonate

Another characteristic of polycarbonate is that it is very soft. Similar to aluminum sheet, it can usually be formed at room temperature without cracking or cracking. Although it may be easier to deform by heating, if there is no heating, there may even be a small angle of bending. This feature makes polycarbonate sheet blanks particularly suitable for prototype applications where metal sheets lack viability (for example, when transparency or non-conductive materials with good electrical insulation properties are required).


 PC is classified as a "thermoplastic" (as opposed to "thermoset"), and its name is related to the way plastics react to heat. The thermoplastic material becomes liquid at its melting point (155 degrees Celsius in the case of polycarbonate). The main useful property of thermoplastics is that they can be heated to their melting point, cooled and heated again without significant degradation. Thermoplastics such as polycarbonate can be burned rather than burned, so that they can be easily injection molded and then recycled.



Application areas of polycarbonate

The three major application areas of PC engineering plastics are glass assembly industry, automobile industry and electronics and electrical industry, followed by industrial machinery parts, optical discs, packaging, computers and other office equipment, medical and health care, films, leisure and protective equipment. PC can be used as door and window glass. PC laminates are widely used in protective windows in banks, embassies, detention centers and public places, as well as aircraft cabin covers, lighting equipment, industrial safety baffles and bulletproof glass.


The application development of polycarbonate is developing in the direction of high composite, high function, specialization, and serialization. It has launched various products such as optical discs, automobiles, office equipment, boxes, packaging, medicine, lighting, films and other products.



Polycarbonate material can also be used in industries such as polycarbonate fabric, industrial polycarbonate, flame retardant polycarbonate and uv stabilized polycarbonate. Pay attention to us to learn more about the possibilities of pc material.
