What is PC (polycarbonate) material, used in injection molding? What are its advantages and disadvantages?

Advantages of PC

 

PC is an amorphous thermoplastic resin with excellent comprehensive performance. It possesses superior electrical insulation, elongation, dimensional stability, and chemical corrosion resistance, as well as high strength, heat resistance, and cold resistance. It also has advantages such as self-extinguishing, flame retardancy, non-toxicity, and colorability. PC plastic can be found in almost every aspect of your life. Its large-scale industrial production and ease of processing also make it relatively inexpensive. Its strength can meet various needs, from mobile phones to bulletproof glass.

 

Disadvantages of PC

 

1. Compared to metals, it is less hard, making its appearance more prone to scratches. However, its strength and toughness are excellent. Whether subjected to heavy pressure or ordinary drops, as long as you don't try to hit it with a stone, it has a long lifespan.

 

2. Not resistant to strong acids, strong alkalis, or ultraviolet rays; resistant to weak acids and neutral oils. PC material - Application areas: Broad-spectrum optical instruments. As an engineering plastic with good transparency, PC is widely used as a substrate for optical discs worldwide. It can be used to manufacture CDs, VCDs, and DVDs, and is also suitable as a substrate for high-density recording optical discs. In particular, the copolymer formed by grafting PC with styrene has excellent application effects.
