lexan PC sheet High mechanical strength

PC (polycarbonate) has high mechanical strength and high impact toughness and high conversion temperature, as well as heat and deformation resistance, operating temperature range from minus 50 degrees to 125 degrees. Feature editing

High mechanical strength, good creep resistance, even at low temperatures, with a very high impact strength; in a large temperature range with a rigid holding force; resistance to energy rays, good electrical insulation, very good dimensional stability , Translucent, physiologically inert, suitable for contact with food.

Application edits

It is widely used in machinery, electronics, automobile, construction, daily necessities and other fields, and is rapidly expanding to aviation, aerospace, electronic computer, optical disc, optical fiber, optical fiber, And so many high-tech fields.

Polycarbonate (PC) is a polymer containing carbonate groups in the molecular chain. It can be classified into aliphatic, aromatic, aliphatic and aromatic compounds according to the structure of ester groups. Which due to the mechanical properties of aliphatic and aliphatic - aromatic polycarbonates is low, thus limiting its application in engineering plastics.

At present, only aromatic polycarbonate has been industrialized. Due to the special nature of the polycarbonate structure, has now become the five largest engineering plastics in the fastest growing general engineering plastics.

Polycarbonate is a tough thermoplastic resin whose name is derived from its internal CO3 group. Can be synthesized from bisphenol A and carbon monoxide (COCl2). The more commonly used methods are melt transesterification (bisphenol A and diphenyl carbonate are synthesized by transesterification and polycondensation).

Polycarbonate (PC) is a polyester of carbonic acid, and carbonic acid itself is not stable, but its derivatives (such as phosgene, urea, carbonate, carbonate)

Certain stability.

Depending on the structure of the alcohol, the polycarbonate may be divided into both aliphatic and aromatic groups.

Aliphatic polycarbonate. Such as polyethylene carbonate, polytrimethylene carbonate and its copolymer, low melting point and glass transition temperature, poor strength, can not be used as structural materials; but the use of its biocompatibility and biodegradable properties can be In the drug release carrier, surgical suture, bone support materials and other aspects of access to applications.

Polycarbonate resistant acid, weak base, resistant to neutral oil.

Polycarbonate is not resistant to ultraviolet light, intolerant alkali.
