In this article we evaluate three different UV absorbers. They all have advantages and associated characteristics. First an introduction of the UV absorbers:

 

本篇文章中我们会分析?#20848;?#19977;种不同的紫外线吸收剂。它们各自都有自己的优点和特征。首先是紫外线吸收剂的基本介绍:

 

OMNISTAB UV 1577 TF is a toluene free hydroxyphenyl triazine UV absorber. Exhibits very low volatility and good compatibility with a variety of polymers. Allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers.

 

OMNISTB UV 1577 TF 是一种无甲苯羟苯三嗪紫外吸收剂,具有很低的挥发性且与各?#24535;?#21512;物?#24049;玫南?#23481;性。可以让聚碳酸酯和聚酯具有比传统苯并三唑类紫外吸收剂更高的耐候性。

 

OMNISTAB UV 3030 is a very low volatile ultraviolet light absorber (UVA) of the cyanoacrylate class, imparting excellent light stability to engineering polymers. Features maximal thermal stability and no inherent color. It can be used to stabilize highly transparent polymers with high extrusion temperatures.

 

OMNISTAB UV 3030是具有低挥发性的氰基丙烯酸酯类紫外线吸收剂,增强工程聚合物的光稳定性,它具有很高的热稳定性且没有固定颜色。它可以用于稳定挤压温度高的高度透明聚合物。

OMNISTAB UV 3638 offers very strong and broad UV absorption with no color contribution. Provides low volatilty. Imparts high UV screening efficiency.

 

OMNISTAB UV 3638提供了更强更广泛的UV吸收范围,具有低挥发性和高紫外线筛?#20013;?#29575;。

Differences and recommendations

产品差异性和应用范围推荐

 

OMNISTAB UV 1577 TF is a hydroxy-benzotriazine UV-absorber active both in UV-B and UV-A regions. It shows very good results in PET photo-stabilization. Can be used for PC but less recommended than UV 3030 as sometimes blooming and build up phenomena were observed during production of PC transparent sheets. Can be used for photo-stabilization of ABS plastics and other engineered plastics as well. More effective than hydroxy-triazole UV absorbers like Omnistab UV 329. Can be recommended for 20 year stability of PET sheets. Less effective than Omnistab UV 1600 (this product is currently in development), meaning requires higher concentration to get the same photo-stabilizing effect.

 

OMNISTAB UV 1577 TF是一种活性羟基苯并三嗪紫外吸收剂,同时适用于A类紫外线和B类紫外线,在PET光稳定方面效果显著。可用于PC材料,但相较于UV 3030效果?#20808;酰?#22240;为在PC透明片材生产过程中,有时会出现起膜和堆积现象。可用于提高ABS塑料及其它工程塑?#31995;?#20809;稳定效果,比OMNISTAB UV 329等羟基三唑类紫外线吸收剂效果更好,可用于维持PET片材20年的稳定性。比起OMNISTAB UV 1600稳定效果差一些(该产品目前正在开发中),这意味着需要更高的浓度才能获得相同的光稳定效果。 

 

OMNISTAB UV 3030 is Cyano-acrylate type UV absorbers active mostly in UV-B region. It is very effective for stabilization of polycarbonate (PC). Stable at processing temperatures of PC (some 300C) without blooming and build up phenomenon on conditions together with Omnistab UV 1600.

 

OMNISTAB UV 3030是一种氰基丙烯酸酯型紫外吸收剂,主要在B类紫外线中作用明显。它对聚碳酸酯(PC)的稳定有很好的效果。在PC加工温度(300)下作用稳定,模具设备上不会出现起膜和堆积现象。可被推荐用于在户外条件和与OMNISTAB UV 1600配合使用条件下,可以?#20013;?#20351;用20年的PC材料。

 

OMNISTAB UV 3638 is a Benzoxazine type UV-absorber with strong absorption in UV-A region and less absorption in UV-B region. Effective in photo-stabilization of PET but of less extent than UV 1577. It possesses high thermal stability. Can be used in different Engineered polymers. Can be recommended for less durable products, e.g. 10 years lasting.

 

OMNISTAB UV 3638是一种A类紫外线吸收率高、B类紫外线吸收率低的苯并恶嗪型紫外线吸收剂。对PET的光稳定效果好,但比UV 1577的光稳定效果差,具有较高的热稳定性,可用于不同的工程聚合物。可推荐用于耐用性差的产品,使产品耐用性达到10年左右。
