| titleOfInvention | Energy absorbing polyurethane foams |
| abstract | An open-celled polyurethane foam is provided having a density of 1.5 to 5.0 pcf, a G value of 30 to 80 over a static load range of 1.0 to 2.0 psi based on a 2.0 inch thickness and a 24 inch drop height and, an airflow in the range of 0.05 to 0.5 scfm, 25 % as compressive strength of 4.0 psi or more prepared by a process comprising reacting, under foam forming conditions: (a) an isocyanate-reactive component comprising (i) 20 to 80 % of a first polyol selected from the group consisting of polyether diols, polyether triols and mixtures thereof having a molecular weight of 2000 to 10,000 and an ethylene oxide content of less than 50 %; and (ii) 80 to 20 % of a second polyol selected from the group consisting of polyether diols, polyether triols, polyester diols, polyester triols and mixtures thereof having a molecular weight of 300 to 1500 and an ethylene oxide content of less than 50 %; (b) a polyisocyanate component comprising 40 to 70 % of diphenylmethane diisocyanate and 30 to 60 % of polyphenylmethylene isocyanate, wherein said diphenylmethane diisocyanate comprises more than 50 % by weight of the 4,4'-isomer; (c) water in an amount of 1 to 7 parts by weight per 100 parts by weight of component (a), wherein components (a), (b) and (c) are reacted at an index of 90 to 130. |
