Material Notes:
This rigid polyurethane foam system is one of a family of polymer systems developed by Northstar Polymers for specific applications. Urethane foams molded with this system exhibit closed cell structure, and its high-density foam structure provides a very good lord bearing capability. The both components are low viscosity liquid and together with its easy mixing ratio of 1: 1 by volume, this material is ideal as a bonding agent structural composite. A user can mix and pour the mixture with common tools without an expensive casting/spray machine. This foam can also be mix/cast by a meter mixing machine. This foam do not use a volatile auxiliary blowing-agent and can be operated in a ambient workplace without being flame/spark-free environment. This combination of features makes MPL-R20B ideal for molded/cast structural parts, cat-in-place structural foam material, structural composites, and many other custom applications.Information provided by Northstar Polymers.
