Dow BETAFOAM™ 89100/89120
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
Material Notes:	BETAFOAM™ 89100/89120 is a low-density, all-water blown rigid polyurethane foam. The components were engineered to produce a foam for providing barrier protection against airborne noise. Foam is produced by the rapid mixing of both components under high shear conditions. These components were formulated for fast reaction and high volume expansion. The foam has adhesion to primed metal surfaces. Information provided by Dow
