Abstract: A method of producing a polyurethane foam for cosmetic application by machine foaming using a polyol component, a polyisocyanate component, a catalyst, a foam stabilizer and an inert gas is disclosed. The polyol component used contains 30 mass % or more of bifunctional polyol with a ratio of primary hydroxyl groups to terminal hydroxyl groups of 70% or more and a number average molecular weight of 1000 to 3000 and has an average ratio of primary hydroxyl groups to terminal hydroxyl groups in the whole polyol component of 50% or more. The polyisocyanate component is used at an isocyanate index ranging from 85 to 130. A supply of the inert gas in terms of a volume at 0° C. and 1 atm is adjusted to two to ten times a total supply of liquid materials of the polyol component, polyisocyanate component, catalyst and foam stabilizer.

Abstract: The present invention provides laminate structures of interior finishing material having suitable air permeability and sound absorbing properties.
