Polymer Antioxidant – prevent polymers thermal oxidation

what are antioxidant?

Antioxidants are used for anti-aging, vitamin has anti-oxidation functions. when it comes to industry,  certain antioxidant work for the same purpose.  antioxidant as used to improve polymers’ high-temperature stability.

Polymer antioxidants including hindered phenolic, amine which belongs to the primary antioxidant,  phosphite, thioesters which belongs to the auxiliary group, and blends of a primary with an auxiliary.

 

what’s antioxidants’ application and how to choose?

Antioxidants are widely used in plastics, rubber, fiber, coatings, and adhesives industry. Basically, antioxidants are used in every polymers processing,  antioxidant selection guide as the table below, For mobile phone user, please click HERE to view PDF copy.
