PU soft foam refers to flexible polyurethane with certain elasticity, commonly known as PU sponge/foam. This kind of foam plastic has good elasticity, generally has the properties of low density, good elastic recovery, sound absorption, heat preservation, etc.

With the continuous expansion of polymer material applications, low molecular weight HALS have been difficult to meet some high temperature processing environments and applications with high standards of material weathering because of the defects of easy migration, volatility, and intolerance of extraction.

Triazine UV absorber is a new type UV absorber developed in recent years. Thanks to its advantages of broad spectrum absorption, high efficiency, good heat resistance and dispersion, Triazines become the research and development hotspot in the field of UV absorbers.
