Sprayable polyisocyanate foam composition |
摘要 |
A formulated resin composition for producing a closed cell rigid polyisocyanate based foam is disclosed. The formulated resin composition for use in a polyurethane froth spraying system includes a hydrofluorocarbon blowing agent, a Mannich polyol, at least one additional polyol, a catalyst system, and a surfactant. The formulated resin composition has a hydroxyl content of at least 400 mg KOH/g and a polyurethane foam produced utilizing the formulated resin composition has a closed cell content of at least 90 percent. The formulated resin composition exhibits a zero ozone depleting potential and produces a polyurethane foam that cures faster than conventional sprayed polyurethane foams. |
