| 摘要 |
The present invention relates to flexible polyurethane foams, the chemical composition of which incorporates polyol ethers with special properties, which in particular stoichiometric ratios confer on the resulting polyurethane foam enhanced properties of postural comfort, hysteresis, resilience, durability and vibration damping, in a wide range of densities and with excellent processability. The invention results in a range of flexible polyurethane foam formulations with which it is possible to produce comfort articles that are noteworthy in terms of seating and cushioning functions, allowing a surprising reduction in thickness and weight of the material obtained, thereby complying with the technical specifications of the vehicle. This reduction in weight leads, furthermore, to a reduction in consumption on the part of the vehicle and therefore less environmental pollution.
