Polymeric polyols are mainly used to produce soft block foams and molded foams with high load-bearing and high resilience, widely applied in fields such as carpet backing, furniture cushioning, vehicle seat cushions, and automotive interior parts. During the foaming process, the solid organic fillers in polymeric polyols act as gas nucleating agents, making the bubbles uniform and improving the foaming process; at the same time, these fillers adhere to the bubble wall, weakening the bubble membrane, increasing the open cell rate, and preventing foam shrinkage, thereby enhancing the load-bearing capacity and strength of the foam.
In addition, polymeric polyols can also be used to prepare materials such as microporous elastomers, adhesives, and sealants, used in the microporous or non-porous polyurethane field, which can improve the modulus and tensile strength and other physical properties of the materials. Compared to ordinary polyurethane soft foams, polyurethane foams produced using polymeric polyols have higher compressive loads and tensile strength, while having a lower density, thus reducing costs.
