Antioxidant AO-68 is a solid phosphite antioxidant with outstanding hydrolytic stability.
Generally, it is used in combination with hindered phenolic antioxidants and hindered amine
stabilizers to contribute improved performance to a variety of polymers.
Antioxidant AO-68 can be used as a processing stabilizer in polymers to help control color
degradations and melt flow.
Antioxidant AO-68 is particularly useful in the stabilization of polyolefins, EVA, olefinic
copolymers when used in conjunction with a phenolic antioxidant.
Antioxidant AO-68 can also be used to stabilize polyesters, polycarbonates, polyamides,
polystyrene, and elastomers.
Use levels can range from 0.10 to 0.80% based on the polymer. |
