Light stabilizer GW-540 properties and application

This product is a white crystalline powder. Melting point 122~124℃. Soluble in ethanol, chloroform, acetone, benzene and other solvents, hard to dissolve in water.

Light stabilizer GW-540 as blocked light stability agent, no UV-absorbing capacity of its own, but you can capture the activity of free radicals produced by polymer degradation, decomposition of excited state molecules of hydrogen peroxide and transfer energy, light effect for the General UV absorber 24 times. This product is applicable to plastics such as polyethylene, polyethylene, good compatibility with resins, processing performance too, besides the light effect, also have good resistance to thermal oxidation resistance. But poor this product is heat-resistant and should not be used in a hot water medium to long-term. In addition, this product is the best at 270 ° c below the temperature processing and use, weightlessness when you exceed this temperature is more serious.

Safety precautions: this product is low in toxicity.
