SABIC PC LEXAN HFD4211 is a 10% glass-filled, injection molding grade product specifically designed for high fluidity and excellent surface appearance. Internal mold release. Polycarbonate (abbreviated as PC in English), also known as PC plastic, is a high molecular polymer containing carbonate groups in its molecular chain. Based on the structure of the ester group, it can be classified into aliphatic, aromatic, aliphatic-aromatic, and other types. Among these, the mechanical properties of aliphatic and aliphatic-aromatic polycarbonates are relatively low, which limits their application in engineering plastics.

Polycarbonate is a tough thermoplastic resin, and its name derives from the internal groups. It can be synthesized from bisphenol A and phosgene (COCl?). The method more commonly used now is the melt transesterification process (synthesized through transesterification and polycondensation of bisphenol A and diphenyl carbonate).

Reaction principle of bisphenol A and diphenyl carbonate:

The three major application areas of PC engineering plastics are the glass assembly industry, automotive industry, and electronics and electrical appliance industry, followed by industrial machinery parts, optical discs, packaging, office equipment such as computers, medical and healthcare, films, leisure and protective equipment, etc. PC can be used as window and door glass, and PC laminated sheets are widely used in protective windows for banks, embassies, detention centers, and public places, as well as for aircraft canopies, lighting equipment, industrial safety barriers, and bulletproof glass.

PC sheets can be used for various signs, such as gasoline pump dials, automobile dashboards, warehouse and outdoor commercial signs, and dot-matrix sliding indicators. PC resin is used in automotive lighting systems, dashboard systems, and interior decoration systems, serving as headlamp covers, reinforced front and rear bumpers, mirror frames, door frame covers, handlebar sleeves, spoilers. PC is applied in junction boxes, sockets, plugs and sleeves, gaskets, television conversion devices, connectors for communication cables under telephone line brackets, switch boxes, telephone exchanges, distribution panel components, and relay housings. PC can be used for low-load parts, such as motors in household appliances, vacuum cleaners, hair washers, coffee makers, toasters, handles for power tools, various gears, worm gears, bushings, guide rails, and refrigerator shelves. PC is an ideal material for optical disc storage media.

PC bottles (containers) are transparent, lightweight, impact-resistant, and can withstand certain high temperatures and corrosive solution washing, making them suitable as recyclable bottles (containers). PC and PC alloys can be used for computer frames, casings, and peripherals, as well as printer parts. Modified PC is resistant to high-energy radiation sterilization, steam sterilization, and baking disinfection, making it suitable for blood collection specimen devices, blood oxygenators, surgical instruments, kidney dialyzers, etc. PC can be used for helmets and safety caps, protective masks, sunglasses, and sports goggles. PC films are widely used in printed charts, pharmaceutical packaging, and membrane commutators.

The application development of polycarbonate is moving towards high composite, high functionality, specialization, and serialization. Various dedicated grades have been introduced for products such as optical discs, automobiles, office equipment, casings, packaging, medicine, lighting, films, and more.
