| Polygard HR |
 |
Polygard HR is a cost effective secondary liquid phosphite antioxidant that functions as a peroxide decomposer and as a processing stabilizer.
When used in conjunction with hindered phenolic and thiodipropionate antioxidants, a synergism is seen.
In addition to improved antioxidant activity of these combinations, Polygard?HR also inhibits discoloration of the polymer caused by some phenolic antioxidants.
Polymer applications include polyolefins, Styrenics and a variety of thermoplastics.
