PC – POLYCARBONATE Polycarbonate (PC) Polycarbonate is strong and very resistant to impact, this material is used when making bullet-proof glass. Not only is polycarbonate an extremely tough and durable thermoplastic material it is also very resistant to temperature. This material is malleable when cool and can bend without cracking. PC has a very high impact strength, far greater than glass and more than ten times that of an acrylic material like PMMA. At the same time, it has less than half the density of glass, but with comparably high level of transparency. In fact, polycarbonate transmits visible light better than many kinds of glass. It is this relatively light weight and transparency, combined with incredible strength, which makes polycarbonate such an attractive material choice for a wide variety of commercial uses. Our Polycarbonate filaments are available in different colors and 1.75mm and 2.85mm diameter.
