紫外线吸收剂uv-1

Yistab UV-1是液态甲眯类紫外线吸收剂，能有效吸收波长为240-350mm的紫外光，吸收峰为308nm，在300-330波段几乎可以完全吸收。而聚氨酯易受到这个波段的辐射而降解。 因此，YISTAB UV-1对聚氨酯制品如软硬发泡、弹性体、人选革、胶黏剂以及涂料都有优异的光稳定性能，从而直到抑制产品老化，增强色泽稳定性，延长使用寿命的作用。

Yistab UV-1 is liquid formamidine ultraviolet absorber. The effective UV absorptivity is in the region 240-350nm. The biggest absorption peak is 308nm. It can almost entirely absorb the ultraviolet radiation in the regin 300-330nm. The polyurethane is easy to degrade due to the radiation of this wave range . So it has excellent light stability for the polyurethane products like flexible foam, rigid foam, elastomer, artificial leather, adhesive and coating etc. It prevents the aging and improves the color stability to prolong the service life of the products.
