In practice, selection of light stabilizers are not always easy, generally focus on several points:

(1) according to the polymer most sensitive wavelength, used within this wavelength range to maximize the absorption coefficient of species.

(2) other additives must be considered, such as antioxidants, stabilizers, lubricants, coloring agents, such as light stabilizers, the effect, should not allow its efficacy in reducing light stabilizers.

(3) some light stabilizers have a certain toxicity in the stabilizer should carefully consider when used for what type of products it should not join the products of plastic materials in contact with foodstuffs.

Above is jiuyu share light stabilizer selection criteria.

Long Yu, Zhangjiagang chemical company is mainly engaged in the development and production of UV absorber, began specializing in the production of UV-absorber UV-531 in 2008, the monthly production capacity of 100 tons/month (production: Nantong, sales to Zhangjiagang). Long-term supply UV-absorber UV-9 168, light stabilizer 770, antioxidant and light stabilizer 944 and other products.
