Northstar Polymers MPP-R02C Semi-rigid Polyurethane Foam Formulation
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
Material Notes:	MPP-R02C is semi-rigid foam formulations for molded foam products. It is closed-cell light foam with some structural integrity. Unlike rigid polyurethane foams, the physical properties of a cured product have some flexibility so it resists cracking and chipping and cracking with an impact force. This foam may be used in production of small to medium light parts with some structural integrity. Information provided by Northstar Polymers.
