YIPACK^® PUB-670 features excellent heat resistance and the ability to absorb ultraviolet rays. It can absorb most of the UVB band ultraviolet light, thereby effectively inhibiting the photodegradation of polymer materials and enhancing the color stability of products. This product can be widely applied in the original liquid of polyurethane shoe soles, polyurethane resins, leather, soft/hard foams, elastomers, adhesives and fabric coatings, reducing yellowing and physical property degradation caused by ultraviolet radiation. YIPACK^® PUB-670 is particularly suitable for polyurethane soles in the polyester polyol -MDI system, enhancing the yellowing resistance level of shoe materials. It has good compatibility in polyurethane materials and is colorless and stainless. The recommended addition amount is 0.5-3.0%.
