What is Polycarbonate (PC)?

Polycarbonate (PC) is strong, with extremely good impact resistance, scratch resistance, and heat resistance. It has low shrink with good dimensional stability and accepts high cosmetic finishes well. However, PC parts possess poor chemical resistance, so an ABS/PC blend or Acrylic material are good alternatives when this is a necessity.
