摘要

Molecular weight reacting jiisoshianeto chemical compound with poly- all of 500 - 3000, the remains quantity of the isoshianeto basis when the prepolymer which can (A), the building a bridge medicine where the number of average hydroxyl groups consists of poly- all 2 - 4 (B) and contains the water (C), (A) content of the isoshianeto basis in 7.0 - 12.0 mass %, it mixes (A) and (B) 2.0 - 5.0 mass %, the remains quantity of the isoshianeto basis when it mixes (A), (B) and (C) 0.01 - 0.5 mass %, (A) poly- all of the raw materials and the Kazuhei equal molecule of all the poly- all when (B) mixes poly- allThe quantity 600 or more, in the non solvent type urethane resin composition which is the air or the containing bubble after pointing the inert gas, it forms in seat condition, the non solvent type poriuretanurea foaming body seat and its production method and has the seat the synthetic leather which it makes heat makes harden and can.
