歐穩(wěn)德光穩(wěn)定劑119是提高高分子材料光穩(wěn)定性的一種物質(zhì)。它能屏蔽紫外線光波，減少紫外線的透射作用；或能強(qiáng)烈地吸收高能量的紫外線(波長(zhǎng)290～400μm)，進(jìn)行能量轉(zhuǎn)換，以熱能形式或無(wú)害的較長(zhǎng)波長(zhǎng)的光把能量放出；或能迅速地使已經(jīng)被紫外線激發(fā)的高分子激發(fā)態(tài)猝滅，回到穩(wěn)定的基態(tài)；或能極為有效地捕捉因紫外光引發(fā)高聚物產(chǎn)生的游離基，從而達(dá)到保護(hù)高分子材料，使其免受紫外線破壞的作用。

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.

常規(guī)的光穩(wěn)定劑通過(guò)吸收可引起塑料老化的紫外光而達(dá)到防止塑料老化的目的。而歐穩(wěn)德光穩(wěn)定劑119作用機(jī)理在于，它可以有效地捕集紫外光引起的塑料本身產(chǎn)生的游離基，因而阻止了導(dǎo)致塑料老化的連鎖反應(yīng)的發(fā)生。這種光穩(wěn)定劑又稱游離基捕獲劑。

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.

歐穩(wěn)德光穩(wěn)定劑LS119的優(yōu)勢(shì)使得它尤其適用于PE農(nóng)業(yè)薄膜、PP纖維和滑石粉填充的PP及TPO汽車部件。還可用于粉末涂料，不僅能帶來(lái)摩電效應(yīng)，還能帶來(lái)光穩(wěn)定性。在聚合物中，尤其是在PP纖維中使用OMNISTAB LS 119的好處是光穩(wěn)定效果高且與多種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.

歐穩(wěn)德LS 119的一般添加水平在0.05-1%之間。須采用適當(dāng)?shù)脑囼?yàn)來(lái)判定特定用途中所添加量是否合適。該產(chǎn)品與其它紫外線吸收劑和光穩(wěn)定劑一起使用，表現(xiàn)出協(xié)同效應(yīng)，包括低分子HALS（如OMNISTAB LS 770、OMNISTAB UV3853）、高分子量HALS（尤其是OMNISTAB LS622）、苯甲酸和紫外線吸收劑。

The general addition level of OMNISTAB LS 229 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.

特點(diǎn)：

-與傳統(tǒng)的HALS相比，第三代HALS降低了與農(nóng)業(yè)化學(xué)品、填料、顏料和其它添加劑的相互作用；

-在聚烯烴中具有出色的熱氧穩(wěn)定性和光穩(wěn)定性，在滑石粉填充的PP和TPO中性質(zhì)尤為突出；

-不變色，揮發(fā)度低，極其耐受遷移。

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.

產(chǎn)品包裝為25公斤紙箱包裝，也可按照客戶要求包裝。

The product is packed in 25kg cartons and can also be packed in accordance with customer requirements.
