ReoFlex 40 Dry Polyurethane rubber. ReoFlex urethane rubbers offer superior physical and performance properties for production casting of wax, plasters, and resins.
ReoFlex urethanes are available in 20A, 30A, 40A, 50A and 60A Shore hardnesses and feature convenient one-to-one by volume mix ratios. Vacuum degassing is not necessary and ReoFlex rubbers cure with negligible shrinkage to a durable rubber that will last in production. ReoFlex "Wet" rubbers will shrink somewhat over time vs. "Dry" formulations.
ReoFlex mold rubbers are used for a variety of applications including making molds to reproduce sculpture and architectural elements, as well as for making special effects, toys and prototypes. Vibrant colors can be achieved by adding So-Strong Color Tints, available from Smooth-On.PropertiesTechnical Properties
