METHOD OF PREPARING ELASTIC FOAMS Russian patent published in 1999 - IPC

Abstract RU 2130466 C1

FIELD: automobile manufacture, civil engineering and other industries, manufacture of sporting articles. SUBSTANCE: polyisohydroxypropylene polyisocyanate containing 2.0 to 4.0 wt % NCO groups is foamed in the presence of latex and at least 20 wt % dry matter at 80-20:20-80 weight ratio thereof. Said latex functions as catalyst, emulsifier, foaming agent and polymer matrix. EFFECT: improved elasticity, greater tensile strength, higher resistance to prolonged and cyclic compression. 14 ex, 1 tbl
