PC is polycarbonate. It is a new type of thermoplastic with a transparency of 90% and is known as a transparent metal. It is rigid and tough, has high impact strength, high dimensional stability and a wide range of use temperature, good electrical insulation properties, heat resistance and non-toxicity, and can be molded by injection and extrusion in CNC Precision Machining.

PC has excellent thermal performance, can be used for a long time between -100℃-130℃, and the embrittlement temperature is below -100℃. Although polycarbonate has poor crack resistance and chemical resistance, high temperature and easy hydrolysis, poor compatibility with other resins, and poor lubricity, it can be modified by adding other resins or inorganic fillers to obtain Very excellent performance.

Polycarbonate application range:

Optical lighting: used to manufacture large-scale lampshades, protective glass, left and right eyepiece tubes of optical instruments, etc., and can also be widely used in transparent materials on airplanes.

Electronic appliances: Polycarbonate is an excellent E (120°C) grade insulating material, used to manufacture insulating connectors, coil frames, tube sockets, insulating sleeves, telephone shells and parts, and battery shells for miner’s lamps. It can also be used to make parts with high dimensional accuracy, such as optical discs, telephones, electronic computers, video recorders, telephone switches, signal relays and other communication equipment.

Mechanical equipment: used to manufacture various gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, and some mechanical equipment housings, covers, frames and other parts.

Medical equipment: cups, tubes, bottles, dental equipment, medicine containers and surgical instruments that can be used for medical purposes, and even artificial organs such as artificial kidneys and artificial lungs.

Other aspects: In construction, it is used as hollow rib double-wall panels, greenhouse glass, etc.; in the textile industry, it is used as textile bobbins, textile machine bearings, etc.; in daily use, it is used as milk bottles, tableware, toys and models.

Advantages of polycarbonate (PC):

① High strength and elasticity coefficient, high impact strength, wide operating temperature range

② High transparency, you can dye any color you want

③ High heat resistance. H.D.T. high

④ Tasteless and odorless, harmless to human body, in line with hygiene and safety, food grade

⑤ Low molding shrinkage, good dimensional stability, easy to process

⑥ Excellent electrical characteristics, high flame retardant level

⑦ UV resistance, good weather resistance

⑧ Good fatigue resistance, good toughness

Disadvantages of polycarbonate (PC):

① Poorly designed molded products are prone to internal stress problems (how to eliminate the internal stress of PC plastic products)

②High requirements for injection molding machine during processing, the processing temperature is about 310 degrees
