低导热系数低密度硬质聚氨酯泡沫塑料用泡沫稳定剂

通过对硬质聚氨酯泡沫塑料绝热性能和无氟发泡体系特点及对聚氨酯硬泡对物料流动性和密度分布要求的分析，开发卅了低导热系数泡沫稳定剂AK8830、AK8882。分析了它们的实验室和工业生产性能，并与进口泡沫稳定剂进行了比较。结果表明，这2种稳定剂具有优异的流动性和密度分布及成核能力，其制得的泡沫制品泡孔细密且密度分布均匀，具有较低导热系数。AK8830和AK8882的综合使用性能达到了国外产品的先进水平，可以满足低导热系数低密度硬质聚氨酯泡沫塑料的生产。

Foam Stabilizer Used in Low Thermal Conductivity and Low Density Polyurethane Rigid Foam

Foam stabilizer with low thermal conductivity, AK8830 and AK8882 were developed successfully based on analysis of the insulation properties of polyurethane rigid foam, the characteristics of CFC-free foaming system, and the flowability and density distribution of material requirement for rigid polyurethane foam. Their properties in lab and industrial production line were researched, and were compared with import product. The results show that AK8830 and AK8882 have good flowability, density distribution and...
