FUNCTIONAL POLYURETHANE FOAM |
| 摘要 |
The present disclosure relates to functional polyurethane foams, and in particular, to functional polyurethane foams including a reaction product of a resin premix and an isocyanate component, wherein the resin premix includes a polyol component and a foaming agent, and the isocyanate component includes monomeric methylene diphenyl diisocyanate (MMDI) in 4 to 70% by weight, carbodiimide methylene diphenyl diisocyanate (CMDI) in 5 to 70% by weight and polymeric methylene diphenyl diisocyanate (PMDI) in 10 to 80% by weight, with respect to the total weight of the isocyanate component. The functional polyurethane foams of the present disclosure are capable of being used for vehicle seats and minimizing vibration transmissibility by absorbing a considerable portion of vibrations that occur while driving. |
