欧稳德光稳定剂119是提高高分子材料光稳定性的一种物质。它能屏蔽紫外线光波,减少紫外线的透射作用;或能强烈地吸收高能量的紫外线(波长290~400μm),进行能量转换,以热能形式或无害的较长波长的光把能量放出;或能迅速地使已经被紫外线激发的高分子激发态猝灭,回到稳定的基态;或能极为有效地捕捉因紫外光引发高聚物产生的游离基,从而达到保护高分子材料,使其免受紫外线破坏的作用。

OMNISTAB LS 119 is a substance that improves the lightight stability of polymer materials. It can shield the ultraviolet ray wave, reduce ultraviolet ray transmission effect; Or it can strongly absorb high-energy ultraviolet rays (wavelength 290 ~ 400, which is in the form of heat energy or harmless longer wavelength light), and conduct energy conversion; Or can make the high polymer excited by ultraviolet ray quench quickly, return to stable ground state; Or it can capture the free radical produced by the high polymer caused by ultraviolet light very effectively, so as to protect the high polymer material from UV damage.

 

常规的光稳定剂通过吸收可引起塑料老化的紫外光而达到防止塑料老化的目的。而欧稳德光稳定剂119作用机理在于,它可以有效地捕集紫外光引起的塑料本身产生的游离基,因而阻止了导致塑料老化的连锁反应的发生。这种光稳定剂又称游离基捕获剂。

Conventional light stabilizers prevent plastic aging by absorbing ultraviolet light that causes it to age. The mechanism of OMNISTAB LS 119 is that it can effectively trap the free radicals produced by the plastics caused by ultraviolet light, thus preventing the chain reaction that leads to plastic aging. This light stabilizer is also called free radical capture agent.

 

欧稳德光稳定剂LS119的优势使得它尤其适用于PE农业薄膜、PP纤维和滑石粉填充的PP及TPO汽车部件。还可用于粉末涂料,不仅能带来摩电效应,还能带来光稳定性。在聚合物中,尤其是在PP纤维中使用OMNISTAB LS 119的好处是光稳定效果高且与多种聚合物相容并容易分散。

The advantages of light stabilizer LS119 make it especially suitable for PE agricultural film, PP fiber and talc filled PP and TPO auto parts. It can also be used in powder coatings, which can not only bring about electro -friction effect, but also bring light stability. The advantage of using OMNISTAB LS 119 in polymers, especially in PP fibers, is that it has high optical stability, is compatible with many polymers and is easy to disperse.

欧稳德LS 119的一般添加水平在0.05-1%之间。须采用适当的试验来判定特定用途中所添加量是否合适。该产品与其它紫外线吸收剂和光稳定剂一起使用,表现出协同效应,包括低分子HALS(如OMNISTAB LS 770OMNISTAB UV3853)、高分子量HALS(尤其是OMNISTAB LS622)、苯甲酸和紫外线吸收剂。

The general addition level of OMNISTAB LS 119 is between 0.05 and 1%.Appropriate tests are needed to determine whether the amount added for a particular use is appropriate. The product is used with other UV absorbers and light stabilizers and exhibits synergistic effects, including low molecular HALS (such as OMNISTAB LS 770, OMNISTAB UV3853), high molecular weight HALS(especially OMNISTAB LS622), benzoic acid and UV absorbers.

特点:

-与传统的HALS相比,第三代HALS降低了与农业化学品、填料、颜料和其它添加剂的相互作用;

-在聚烯烃中具有出色的热氧稳定性和光稳定性,在滑石粉填充的PP和TPO中性质尤为突出;

-不变色,挥发度低,极其耐受迁移。

Features:

- compared with traditional HALS, the third-generation HALS reduce the interaction with agricultural chemicals, fillers, pigments and other additives;

- excellent thermal and oxygen stability and optical stability in polyolefin, especially in PP and TPO filled with talc powder;

- no discoloration, low volatility, extremely resistantto migration.
