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. |
