摘要： A sealing material is prepared by furnishing a liquid composition comprising a polydiene or polyolefin polyol, a polyisocyanate compound, a foam stabilizer, and a blowing agent, uniformly dispersing an inert gas in the liquid composition by mechanical agitation to form a bubbled composition, shaping the bubbled composition into a sheet shape, and heat curing the bubbled shape at a temperature below the decomposition temperature of the blowing agent. The sealing material is lightweight and has a high blowing magnification. On use, the sealing material is disposed in a cavity of an automotive pillar or similar member and heated for foaming to fill the cavity with the foamed product.
