摘要 |
A method for the manufacture of paper faced foam which comprises (a) applying a foam-forming mixture to at least one advancing cellulosic sheet or composite thereof with an air- and/or moisture-impermeable material, the cellulosic sheet (i) being impregnated with cured polyisocyanate, (ii) being sufficiently flexible for unwinding from a roll for conveyance along a production line and (iii) having a moisture content which does not exceed about 10 percent and is evenly distributed throughout the cellulosic sheet, and (b) foaming and curing the faced foam-forming mixture. |
