| Abstract: | The advance of study on heat-resistant of the polyurethane elastomer was rewewea, The influencing of low polymer polyols, isocyanates, catalysts, crosslink agent and chain extender on heat resistance of polyurethane elastomer were discussed. Organic heterocyclie introduction, cross-linked structure, adding inorganic filler, nano-composite materials could improve the heat resistance of the polyurethane elastomer effectively, and it will give polyurethane elastomer material excellent mechanical properties at higher temperature. |
