Solve Material Yellowing, Aging & High-Temp Failure! The Complete Selection Guide to 20 Antioxidants

The life cycle of materials is a silent struggle against time.

In industrial manufacturing and everyday life , we often witness such regrets : the once jade-whiite plastic shell gradudlly yellows , the glossy paint loses its luster , the tough rubber quietly cracks in the wind and rain , And even the moment of high-temperature processing , the performancce of the material has been greatly reduced .

Up to 90% of the failure of polymer materials , and its deadly source , points to the same culprit-oxidative aging !

In the face of the relentless erosion of light , heat , and oxygen , how can we inject a”life-enhancing drug “ into the material ? The answer lies in a sophisticated recipe . Today , we will deconstruct it for you in depth . The underlying logic and application scenarous of 20 core antioxidants . Covers main resistivity , auxiliary resistivity , composite and specialty types .

Weather you are a research and develpoment formulator in the field of plastics , coatings or rubber , this guide will help yo directly select the type  . Tack the four core pain points of the thermooxygen ageing , yellowing , poor weather resistance and short life span .!

Main antioxidants of blocked phenols (long-lasting antioxidants against oxygen and anti-yellowing core) Their core mechanism is to accurately capture the free radicals produced during the material degradation process,thus cutting off the oxidation chain reaction at the source.This type of addictive is the absoult core of giving products a long service life and preventing the yellowing of the product at a later stage .
