▎ 摘　　要

NOVELTY - A flexible polyurethane foam comprises flexible-polyurethane-foam composition which contains a polyol, isocyanate, a foaming agent, a catalyst, and an additive which is graphene. Air permeability (JISK6400-7) is 40-250 L/minute. USE - A flexible polyurethane foam for article e.g., pad for bedding, pillow, mattress, floor seat cushion, pad for legless chairs, and garments, pad for brassieres, pad of seat for vehicles, and cushion (all claimed). ADVANTAGE - The heat containment by a body heat is prevented. The flexible polyurethane foam has favorable thermal conductivity to protect the confinement of heat and steam. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing the flexible polyurethane foam which involves foaming the flexible-polyurethane-foam composition in which a polyol, isocyanate, a foaming agent, a catalyst, and an additive are blended where the additive contains a graphene.
