Northstar Polymers MPP-A47A Liquid Castable Polyurethane

MPP-A47A is a room-temperature-cure liquid castable polyurethane system. This ether-base polyurethane system is used in applications such as mold-making, prototyping, production of cast parts, potting, tool-making, and many other applications. MPP-A47A is designed for an easy operation for industrial applications without special casting or heating equipment. The mixing ratio between part-A (MPN-023) and part-B (PBA-058) is 1:3 by volume. Its low viscosity also makes it easy to achieve replicating the details of the mold/original with a fine resolution. Urethane elastomer parts made of this system exhibit: Fine resolution of mold details Good resiliency and elongation Good cut/tear resistance for its class Good performance in wet environments Easy-to-use room-temperature-curable Small shrinkage factor The suitable applications of MPP-A47A include stamps/patterns and concrete molds designed to transfer a decorative image to wet surfaces. Its property of small shrinkage rate provides users with a tight dimensional stability when a replication is made. It is also suitable for many other custom applications where flexibility and strength of the parts are required.Information provided by Northstar Polymers.
