New Performance Booster for Polyolefins - OMNISTAB UV3529

聚烯烃塑料是通用塑料的一种，它主要包括聚乙烯(PE)、聚丙烯(PP)和POE、EVA、MMA等高级烯烃聚合物。是一类产量最大、应用最多的高分子材料；其中以聚乙烯、聚丙烯最为重要。由于原料丰富、价格低廉、容易加工成型、综合性能优良等特点，在现实生活中应用最为广泛，其在汽车上应用也越来越重要，并有逐步扩大之趋势。聚烯烃塑料具有密度小、物理化学综合性能良好、着色性好、加工性好、价格低廉等优良特性，但长期使用会有易老化、易变形等明显缺陷，通常通过改性来降低其缺陷性，扩大使用范围。

Polyolefin plastics are a type of general-purpose plastics, mainly including polyethylene (PE), polypropylene (PP), and advanced olefin polymers such as POE, EVA, and MMA. It is a type of polymer material with the largest output and the most applications. Among them, polyethylene and polypropylene are the most important. Due to its abundant raw materials, low price, easy processing and shaping, and excellent comprehensive performance, it is the most widely used in real life. Its application in automobiles is also becoming increasingly important and shows a gradually expanding trend. Polyolefin plastics possess excellent properties such as low density, good comprehensive physical and chemical performance, good colorability, good processability, and low cost. However, over long-term use, they may have obvious defects such as easy aging and deformation. Usually, modification is carried out to reduce these defects and expand their application range.

受阻胺类光稳定剂（HALS）是一类具有空间阻碍的有机胺类化合物，主要包括哌啶衍生物、咪唑酮衍生物和氮杂环烷酮衍生物等系列。其是聚烯烃中非常重要也是应用最为广泛的添加剂之一，是一种起光稳定作用的优良新型光稳定剂。受阻胺对高分子和有机化合物的光氧降解反应有很好的抑制效果，主要应用于塑料、合成纤维、涂料中，尤其是在薄膜、纤维等薄制品中具有不可替代的作用。其中，哌啶类衍生物研究得比较多，发展也最快，已有很多品种供应市场，其分子结构中均含有以下结构单元。

Hindered amine light stabilizers (HALS) are a class of organic amine compounds with spatial hindrance, mainly including series such as piperidine derivatives, imidazolone derivatives and azocyclic ketone derivatives. It is one of the most important and widely used additives in polyolefins and an excellent new type of light stabilizer that plays a role in light stabilization. Hindered amines have a very good inhibitory effect on the photo-oxidative degradation reaction of polymers and organic compounds, and are mainly applied in plastics, synthetic fibers, and coatings, especially playing an irreplaceable role in thin products such as films and fibers. Among them, piperidine derivatives have been studied more extensively and developed the fastest. There are already many varieties available in the market, and their molecular structures all contain the following structural units.

受阻胺光稳定剂按其分子量来划分，主要分为低分子量和高分子量两类。比如常见的LS770属于低分子量光稳定剂，而LS622，LS944，LS2020等属于高分子量光稳定剂，以上这些都是聚烯烃中比较常见的光稳产品。

Hindered amine light stabilizers are mainly classified into two types based on their molecular weight: low molecular weight and high molecular weight. For instance, the commonly seen LS770 is a low-molecular-weight light stabilizer, while LS622,LS944, LS2020, etc. are high-molecular-weight light stabilizers. All of the above are relatively common light-stabilized products in polyolefins.

我司新推出的一款光稳定剂产品--OMNISTAB UV3529，其结构上同时含有三嗪和受阻酚结构，能够吸收紫外线的同时捕捉自由基，具有自协同作用，而且OMNISTAB UV3529还是一款高分子量的受阻胺稳定剂。

Our company has newly launched a light stabilizer product --OMNISTAB UV3529. Its structure contains both triazine and hindered phenol structures, which can absorb ultraviolet rays and capture free radicals at the same time, having a self-synergistic effect. Moreover, OMNISTAB UV3529 is also a high-molecular-weight hindered amine stabilizer.

² OMNISTAB UV3529产品优势:

> 低聚物HALS添加剂，可为聚合物提供长期紫外线防护和热防护；

> 与填料、颜料和其他添加剂的反应型更低；

> 对颜色影响小、对变色和气熏黄变具有高耐性；

> 挥发性非常低，与大多数聚合物相容。

² Product advantages of OMNISTAB UV3529:

> It is a oligomer HALS additive that can provide long-term UV protection and thermal protection for polymers;

> It has a lower reactivity with fillers, pigments and other additives;

> It has a small impact on color and is highly resistant to color change and fumigation yellowing.

> It has very low volatility and is compatible with most polymers.

因此，OMNISTAB UV3529可广泛适用于聚烯烃（PE,PP,TPO），如纤维和胶带，薄膜，片材，管道，模塑部件等；能够进一步提升聚烯烃材料的长效性能，扩展聚烯烃材料在更高端领域的用途。

Therefore, OMNISTAB UV3529 can be widely applied to polyolefins (PE,PP,TPO), such as fibers and tapes, films, sheets, pipes, molded parts, etc. It can further enhance the long-term performance of polyolefin materials and expand their applications in more advanced fields.
