Polycarbonate is a lightweight material with the highest impact strength; so much so that it’s almost unbreakable. In contrast to the majority of thermoplastics, polycarbonate can withstand large plastic deformations without breaking, or even cracking.

This allows it be processed and formed at room temperature. The downside to polycarbonate is its low scratch resistance. When considering polycarbonate, there are various brands to choose from, including Lexan and Makrolon. Some uses for the material include machine guards, eyewear products, windows, electronics and outdoor lighting fixtures.
