Abstract
Polyurethane foams formed using a specific mixture of polyether and graft polyols with toluene diisocyanate have fine cell size (over 70 pores per inch) and higher durability with IFD retention over 70% after 12,000 cycles of roll-shear. The foam-forming ingredients are mixed together and foamed at controlled pressures in the range 1.0 to 1.5 (absolute), preferably 1.05 to 1.5 bar (absolute). The foams make particularly good carpet cushions.
