Viscoelastic polyurethane foam |
| abstract |
The invention provides the viscoelastic polyurethane foam of the density of a kind of 1-30 of having pound/cubic feet, it is by comprising isocyanate component, the isocyanate-reactive component that is substantially free of tolylene diisocyanate and the composition with chainextender of the main chain that contains 2-8 carbon atom forms.Described chainextender also has the weight-average molecular weight less than 1,000, and exists based on the amount of the described composition of 100 weight parts with the 5-50 weight part.Described viscoelastic polyurethane foam has 15-35 ℃ second-order transition temperature and the tan δ peak value of 0.9-1.5. |
