Abstract

PURPOSE:To obtain the titled composition useful as a joint filling material for building structure, having excellent contraction and expansion properties and large sound insulating effects, comprising an elastomer having a specific Young's modulus after curing, a sealing material of a moisture-curing one component type or two component reaction curing type comprising a urethane polymer composition. CONSTITUTION:For example, (A) a urethane polymer is blended with (B) 24.5% (volume ratio of filler) barium powder (4.3 true specific gravity and 13mu average particle diameter) to give the aimed composition which is an elastomer of a moisture-curing one component type or two component reaction type, having >=1.8 specific gravity and <=1X10<2>kgf/cm<2> Young's modulus after aging and has excellent sound insulating properties in the whole audio-frequency range without being influenced by coincidence effects.
