Rigid 10K Resin is a heavily glass-filled, ultra-stiff material comparable to glass- and fiber-filled thermoplastics. It delivers a smooth, matte, polished surface finish and offers excellent resistance to heat and chemicals.

Ideal for precision industrial applications, Rigid 10K Resin is well-suited for molds, jigs, dies, and other tooling used in injection molding, thermoforming, and blow molding. It’s also an excellent choice for functional prototypes and end-use parts that demand dimensional accuracy and stability under high temperatures and pressures.
