Specific gravity: 1.18-1.20 g / cm3 
Molding shrinkage: 0.5-0.8% 
Molding temperature: 230-320 ° C 
Drying conditions: 110-120 ° C 8 hours

Material performance:
High impact strength, good dimensional stability, colorless and transparent, good coloring, good electrical insulation, corrosion resistance and wear resistance, but poor self-lubrication, stress cracking tendency, high temperature easy hydrolysis, poor compatibility with other resins.

Suitable for making small instrument parts, insulating transparent parts and impact resistant parts

Molding performance:
1. Amorphous material, good thermal stability, wide forming temperature range and poor fluidity. Low moisture absorption, but sensitive to water, must be dried. The molding shrinkage rate is small, and it is prone to melt cracking and stress concentration. Therefore, the molding conditions should be strictly controlled, and the plastic parts must be annealed.

2. High melting temperature, high viscosity, more than 200g plastic parts, it is advisable to use a heated extension nozzle.

3. The cooling speed is fast, the mold casting system is based on the principle of coarse and short, and it is better to set the cold material well, the gate should be large, and the mold should be heated.

4. If the material temperature is too low, it will result in lack of material, the plastic parts will be dull, the material temperature will be too high, and the plastic parts will foam. When the mold temperature is low, the shrinkage rate, elongation, impact strength are high, and the bending, compressive and tensile strengths are low. When the mold temperature exceeds 120 degrees, the plastic parts are cooled slowly, and the mold is easily deformed.

Applications:
Optical illumination
The left and right eyepiece tubes used to manufacture large lampshades, protective glasses, optical instruments, etc., can also be widely used for transparent materials on aircraft.

Electronic appliances
Polycarbonate is an excellent E (120 ° C) grade insulation material used in the manufacture of insulated connectors, coil frames, pipe sockets, bushings, telephone housings and parts, battery shells for miner's lamps, etc. 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. Polycarbonate thin touch is also widely used as a capacitor, an insulating bag, a tape, a color video tape, and the like.

Equipments
Used in the manufacture of various gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, as well as parts such as mechanical equipment housings, covers and frames.

Medical equipment
Cups, cans, bottles, and dental instruments, drug containers, and surgical instruments that can be used for medical purposes, and even artificial organs such as artificial kidneys and artificial lungs.

Other aspects
The building is used as a double-walled hollow ribbed board, a greenhouse glass, etc.; it is used as a textile tube and a textile machine bush in the textile industry; as a bottle, tableware, toy, model, LED lamp housing and mobile phone case for daily use.
