In modern society, the product such as synthetic fiber of coating plastic rubber falls in sunlight or strong fluorescence (because contain harmful ultraviolet ray to compare common fluorescent lamp more), cause ego oxidation because of absorbing ultraviolet ray, bring about polymer to degrade, make the appearance of the product and physical and mechanical performance deteriorate, this process calls photooxidation reduction or photoageing.

JADEWIN 328 is a kind of light yellow powder solid, which can effectively absorb ultraviolet radiation of 220-340 nanometers, but rarely absorb visible light. It has good thermal stability and optical stability, light color, non-toxic compatibility, low volatile and easy to process.

JADEWIN 360 is a kind of high efficiency ultraviolet absorption agent, can be widely and a variety of resins compatible, has a very low volatility, no color change no pollution in the processing temperature under the non-volatile ultraviolet absorption agent, and light yellow solid powder synergism when used with light stabilizer, insoluble in water, soluble in ester benzene solvents, with high thermal stability.

Everyone is familiar with blue light, which is a part of natural visible light. Sunlight and electronic screens can emit blue light. Now, mobile phone toughened film glasses, lenses and lenses that prevent blue light are all necessities in our life.
