                                                              Smisorb系列PU耐黄剂为液态紫外光稳定耐候剂,具有与树脂相容性好、不易迁移、低挥发性、对短波长UVB紫外线吸收优异、抗变色性耐候性能佳等特点。


                                                              Smisorb系列PU耐黄剂具有较高极性,主要应用于聚氨酯树脂、PU合成革、聚酯多元醇、聚醚合成、PU海绵发泡、TPU造粒及成型成膜、CPU预聚体合成加工、环氧树脂合成及加工、胶粘剂、弹性体、光固化涂料等极性制品领域,都具有优异的耐候表现性能。

                                                               

                                                              Smisorb系列PU耐黄剂能够强烈吸收280~340nm紫外光,几乎不吸收可见光,特别是对芳香族聚氨酯的紫外线灯照测试及室内耐黄测试效果优异,且为液体易于生产加工添加,与硬段--MDI/TDI等异氰酸酯、软段--多元醇等聚氨酯生产大料有高度的相容分散性,从而更有效地提升PU制品的耐老化抗黄变性及延长存放时间的耐变色性等优良性能。


                                                              另外,Smisorb中两款PU专门耐烟熏特殊品,在耐烟气熏测试、提升PU制品抗汽车尾气/废气、抗NOx等氮氧化合物污染气体对PU制品的攻击和耐黄变性上有极好应证。

                                                               

                                                              此外,针对现今PU革制品、PU海绵制品的无酚化环保的大发展方向,以及应对人体自身健康发展的需要,在无酚化领域的拓展及诉求日益显现,目前我司技术部门针对该方面开发出2类抗氧化及耐黄变产品以因应市场日新月异的变化,现已得到欧美、韩国、日本等客户的认可和采用,该类产品的特殊领域效用势必得到更多的聚氨酯从业人员的认证和受用。


                                                              Smisorb系列PU耐黄剂推荐添加量:0.3-2%,根据不同测试标准和要求,采用针对性产品和剂量,具体使用方法和规范请详询我司专业技术/市场人员。

                                                               

                                                              注:Smisorb系列PU耐黄剂产品:Smisorb 115、Smisorb 201、Smisorb 202、Smisorb 203、Smisorb 2030、Smisorb 2050、Smisorb 2073、Smisorb 2090、Smisorb 2095......
