PC processing method

Polycarbonate abbreviation "PC" is a colorless and transparent amorphous thermoplastic material. The colorless, transparent and excellent impact resistance makes it widely used in many other industries. Daily application of common CD / VCD discs, bottled water bottles, baby bottles, bullet-proof glass, resin lenses, bank anti-bullet glass, front shade, animal cages, moon astronaut's helmet visor and smart phone's body shell, and so on.
Polycarbonate (PC) number of processing methods:

   Polycarbonate injection molding, extrusion, molding, blow molding, thermoforming, printing, adhesive, coating and machining, the most important processing method is injection molding.

1 Before molding must be pre-drying, moisture content should be less than 0.02%, trace moisture in high temperature processing makes products to a whitish color, silver and bubble, PC at room temperature has a considerable forced high-elastic deformation.

(2) Impact toughness, it can be cold, cold drawing, cold rolling, such as cold forming. Extrusion PC molecular weight greater than 30,000, gradient compression screw.

3 aspect ratio of 1:18 to 24, the compression ratio 1:2.5, can be extrusion blow molding, injection - blow Note - pull - blowing molding high-quality, transparent bottle. PC alloy variety, improve PC melt viscosity (processability) and products easy to stress cracking and other defects.

4. PC with different polymers to form alloys or blends to improve the material properties.

5 specifically PC / ABS alloy, PC / ASA alloy, PC / PBT alloy, PC / PET alloy, PC / PET / elastomer blends, PC / MBS blend, PC / PTFE alloy, PC / PA alloy and so on.

6 advantages of using two material properties, and reduce costs, such as PC / ABS alloy, PC main contribution of high heat resistance, good toughness and impact strength, high strength, flame retardant, ABS is able to improve formability The apparent quality, lower densities.
