High-temperature resistant and anti-yellowing agent for light-colored plastic

Light-colored plastic products in the production and processing and use of the process, when subjected to light, heat, oxygen, chemical erosion, moisture and other influences, it is very easy to occur yellowing and discoloration problems. Yellowing not only affects the aesthetics of the material, but also means that the structure and performance of the material has undergone significant changes.

> What are the main factors of plastic yellowing?

The influence of ultraviolet radiation, when the material absorbs light energy, the molecular chain on the absorbed part will produce conjugated double bonds or hydrocarbon bond cleavage, causing yellowing phenomenon;

Heat, the influence of oxygen molecules, with the passage of time, the material will undergo oxidation reaction, heat will accelerate the oxidation process of the material, the formation of peroxide structure, it is easy to produce free radicals, resulting in material discoloration;

Other factors such as the improper additives added in the materials, the presence of moisture, impurities and production and processing processes, which may reduce the stability of the material.

> OMNISTAB additives could help you solve the problem of fading and yellowing of light-colored plastics!

OMNISTAB AO-80 is a high-temperature resistant asymmetric hindered phenol antioxidant. Compared with other hindered phenol antioxidants, AO-80 has excellent thermal stability, does not produce phenol yellow or red phenomenon, and can continue to provide excellent anti-heat and oxygen degradation protection for the material in the high-temperature processing and use process, to maintain the initial material color, and to enhance the aesthetics of the product.

When OMNISTAB AO-80 is combined with high molecular sulfur antioxidants, such as OMNISTAB AN800 and OMNISTAB AN802, it can provide better heat aging resistance. OMNISTAB AO-80 is suitable for most plastics, polyolefins and all kinds of elastomers, especially for PE, PP, PA, PUR, POM.

Besides AO-80, OMNISTAB HN130, OMNISTAB AN9142 and OMNISTAB AN1790 are also excellent anti-yellowing agents, which are effective in solving NOx yellowing and gas fuming yellowing. Welcome to your inquiry!
