Here at FastForming, we work with all thermoformable plastics and engineering resins. Not every material is an appropriate choice for every project, so our engineers are standing by to help you select the best type of plastic for your application. In addition to price point, we base our recommendations on characteristics like density, dielectric strength, and thermal conductivity (among many, many others!).

The following list names the most common thermoformable materials, but it is by no means exhaustive:
