Polycarbonate is an all-rounder

This impressively tough and transparent material can withstand high impact over a wide range of temperatures, has a high heat deflection temperature, and has a high modulus of elasticity, making it a great fit for construction applications such as windows, skylights, and roof domes. Of course, that’s only an extremely small view into what polycarbonate is capable of in the industry.

Polycarbonate / Lexan® material absorbs very little moisture and has high-voltage insulating properties. This makes it ideal for use in electrical and electronic components. Its transparency also makes it a superior option for structural applications that require, or otherwise would like, healthy sightlines.

Polycarbonate is commonly used in anti-ballistic panels (aka bulletproof glass). If that doesn’t stand testament to its impact absorption, we’re not sure what else would. If you still need more convincing, it’s also got a lot of other great stuff:

  • Unmatched clarity
  • Very low moisture absorption
  • Excellent thermal stability
  • High tensile, shear, and flexural strength
  • Low deformation under load
  • Low coefficient of thermal expansion

This basically just means that polycarbonate thermoplastic is an absolutely resilient, powerful beast that won’t quit out on your projects.
