Product Details

Properties

Highly effective phosphite - secondary antioxidant

low volatile, function more efficient, and more use with hindered phenolic antioxidants.

Application

Widely used in polyethylene, polypropylene, polystyrene, nylon, polycarbonate and other products. Generally not used alone, often used together with blocked phenolic antioxidants such as 1010, has a synergistic effect to provide excellent thermal processing anti-aging degradation properties for the polymer, and can well protect the high temperature discoloration phenomenon of polymer materials.
