Abstract

A system and method for forming a polyurethane foam includes supplying an isocyanate component from a source of isocyanate to a proportioner. A resin component from a source of resin is supplied to a metering unit and an additive having an unstable state from a source of additive is supplied to the metering unit. The resin component and the additive form a reactive mixture when combined. The system and method includes delivering the reactive mixture by the metering unit to an accumulator and storing the reactive mixture in the accumulator. The system and method further includes demanding a supply of the reactive mixture with the proportioner and supplying the reactive mixture by the accumulator to the proportioner and mixing the reactive mixture with the isocyanate component by the proportioner to form the polyurethane foam.
