This highly glass-filled resin is the stiffest material in our engineering portfolio. Choose Rigid for precise industrial parts that need to withstand significant load without bending.


  • Aerodynamic test models

  • Heat resistant and fluid exposed components, jigs, and fixtures

  • Simulates stiffness of glass and fiber-filled thermoplastics


stiff and strong!

engineered not to bend, deflect, or break


There are two options, Rigid 4000 and Rigid 10k, each named after their tensile modulus.

Use Rigid 4000 for general load-bearing applications

Use Rigid 10K for the stiffest option possible. Highly resistant to heat and chemicals.
