“…9,10 In the production process of polyurethane foam, according to different application requirements, the polyol, isocyanate and catalyst types can be adjusted to produce different properties of foam, such as high temperature resistant foam, ame retardant foam, acoustic insulation foam, high resilience foam, etc. 11,12 In the 21st century, with the rapid development of global industrialization, petrochemical resources are getting depleted, and problems such as serious petroleum-based pollution and difficulties in waste degradation have seriously affected the development of polyurethane industry. [13][14][15][16] Therefore, it is particularly important to nd suitable alternatives for petroleum-based materials.…”
