Last article we learned the first two methods to solve the color masterbatch after use fade, today Qingdao Sainuo
polyethylene wax manufacturer continue to take you to understand the remaining two solutions.
1. Oxidation resistance
After oxidation, some organic pigments degrade or change their color gradually, which is the process of high
temperature oxidation. Second, encounter strong oxidant (such as chromate in chrome yellow) occurred in the
oxidation. Color Lake, Azo pigment and chrome yellow mixed use, the red will gradually fade.
2. Acid and Alkali resistance
The fading of Colored Plastic Products is related to the chemical resistance (acid and Alkali resistance, oxidation
and reduction resistance) of colorants. For example, molybdenum chrome red is resistant to dilute acid, but
sensitive to Alkali, cadmium yellow is not resistant to acid, these two pigments and Phenol formaldehyde resin
play a strong role in the reduction of some colorants, seriously affecting the color masterbatch of heat resistance,
weather resistance and fading.
