Manufacture of polyurethane foam |
| abstract |
Substantially water blown flexible polyurethane foams, based on methylene diphenyl isocyanates, having a density ranging from 15-25 kg/m<3>. Such foams may be obtained through a process substantially avoiding halocarbon blowing agents, which comprises reacting methylene diphenyl isocyanates with water and one or more isocyanate-reactive compounds selected from polyols and polyamines with a functionality of 2-4 and an average equivalent weight ranging from 750-5000, while the isocyanate index ranges from 10 to 60, and weight ratio of the isocyanate-reactive compound(s) to water is less than 20. |
