In order to accomplish this change, our research have made several important break-through by revising new formulation especially in (1) catalyst mix,(2) adjustment of water content,(3) addition of chain extenders and crosslinkers, and(4) utilization of long-chained polyols. By doing so, the general performances of our new non-yellowing foam products are comparable to those of the traditional TDI based products. In certain mechanical properties in areas such as tensile strength, split tear strength, and elongation our measured values of 1.89 kg/cm2, 1.47 kg/cm, and 355 % respectively have out-performed the old materials.

The results showed that the m-PUE had better heat-resistant properties, lower glass transition temperature, higher thermal decomposition temperature and better damping property. The internal friction peak was changed from 10 ℃ to -10 ℃, while the tan δ was changed from 0.28 to 0.46. The hardness, tensile strength and tear strength of m-PUE decreased with the increase of the THEIC content. However, the swelling ratio of PUE was increased meaning a deteriorated solvent resistance property.

结果表明，引入IS环后，PUE的耐热性能有提高；IS改性的PUE的内耗峰比未改性的窄，峰位由10℃移到-10℃，且内耗峰值增大（tanδ由0.28增大到0.46），玻璃化温度降低，而阻尼性能得到提高；引入IS环的PUE的硬度和其它力学性能比未改性的PUE有所降低；随着固化剂中THEIC用量的增加，PUE的溶胀率增大，即IS改性PUE的耐溶剂性变差。

Experimental results showed that the CPF improved the retention of precipitated calcium carbonate filler significantly.
