PROBLEM TO BE SOLVED: To provide a rubber foamed material suitable for puffs for makeup, industrial materials, building materials or automotive parts such as soundproofing materials, heat insulating materials, cushioning materials, gaskets, sealing materials, packing materials, containers, packaging materials or floor materials having excellent cushioning properties, elasticity, chemical and weather resistances, flame retardance and compression set properties. SOLUTION: The rubber foamed material is obtained as follows. A rubber composition containing (A) 100 pts. mass of a polymer containing 30-100 mass% of a polar group-containing polymer, (B) 1-30 pts. mass of an organic foaming agent and (C) 0.1-10 pts. mass of an organic peroxide is extruded into a prescribed shape. The extruded composition is heated, and cross-linked and foamed. COPYRIGHT: (C)2004,JPO |
