A type 4, extra hard reinforced dental die-stone for the production of models and removable dies in fixed prostheses, removable prostheses and implantology. With a compact, marble-like finish and an accurate reproduction of detail, Elite Master colours are optimised for detection by all modern laser and optical scanners. The resin particles inside the formulation provide high elasticity and splintering resistance for optimal chamfering. The resin particles reduce water absorption, guaranteeing the accuracy of the model. Formaldehyde free. Compressive strength at 1 hr = 50 MPa, Expansion at 2 hr = 0.08%.
