ConProTec Inc. (Salem, N.H., U.S.A.) announces the availability of its MR line of rotary mixers. Designed for use with meter/mix/dispense machines (MMD), MR Mixers provide a dynamic mixing solution for two-component adhesives by rotating a mixer element on specially modified MMD manifold heads. Ideally suited for hard-to-mix foams and urethane elastomers, the mixers are constructed of durable polyacetal to resist the added shear of dynamic mixing. Each mixer consists of twelve elements and is available with inner diameters of 6 mm, 8 mm, 10 mm and 13 mm (0.24 inches, 0.31 inches, 0.39 inches, 0.51 inches). Made from polypropylene, the bell mouth fits all standard MMD manifold heads. The mixers' low cost allows users to discard the entire unit after use, eliminating costly cleaning associated with internal dynamic mixing.
