Function:
Antioxidant function: As a phosphite antioxidant, it can decompose peroxide compounds produced during the processing and use of polymers, prevent their cracking and induce thermal oxidation degradation of polymers, thereby delaying or inhibiting the oxidation process of polymers and extending the service life of polymers.
Synergistic enhancement function: It can be used in conjunction with main antioxidants such as hindered phenols to play a synergistic role, significantly improve the antioxidant effect of polymers, and more effectively inhibit the color change and melt index change during polymer processing.
Color improvement function: It helps to improve the color of polymer materials such as plastic products, so that the products maintain a good appearance quality and reduce color problems such as yellowing caused by oxidation and other factors.
Application:
Plastic industry: widely used in various synthetic resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS resin, polyester, etc., which can improve the stability of plastics during high-temperature processing and prevent the performance of plastics from deteriorating due to oxidation during processing and use.
Rubber industry: can be used as an antioxidant and heat stabilizer for rubber, used in natural rubber, synthetic rubber and its products, can delay the aging process of rubber, improve the heat resistance, weather resistance and ozone resistance of rubber, and extend the service life of rubber products.
Coating and ink industry: added to coatings and inks, it can prevent the resin and other components in coatings and inks from oxidizing and deteriorating during storage and use, improve the storage stability and performance of coatings and inks, and improve their color and drying performance.
Food packaging materials: because it is non-toxic and pollution-free, and has been approved by relevant food and health agencies in many countries, it can be used for food packaging materials. It can play an antioxidant role without affecting food safety, protect the performance of food packaging materials, and indirectly extend the shelf life of food.
