Description
[Smooth-On, Easton PA] A series of elastomeric urethane rubbers most often used for casting flexible molds of wax, plasters, and resins. ReoFlex™ rubbers are composed of a 2-part liquid system: Part A contains Polyurethane prepolymenr (95-99%), Dioctyl phthalate (0-5%) and diisocyanates. 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.
