Chemical Name:Tris(2,4-di-tert-butylphenyl) phosphite
Molecular Formula:C₄₂H₆₃O₃P
Molecular Weight: 646.9
CAS No.:31570-04-4
Properties
Most widely used Phosphite ester antioxidant.
low volatile, resistant to hydrolysis stability is good, and more use of hindered phenolic antioxidants compound
Application
Widely used in polyethylene, polypropylene, nylon, polycarbonate, styrene copolymer and other products. Generally not used alone, often used together with impeded phenolic antioxidants such as 1010 1076, has a synergistic effect, provides excellent melt processing anti-aging degradation properties for the polymer, and can well protect the high temperature discoloration phenomenon of polymer materials.
Storage
Keep container tightly closed in a cool, well-ventilated place.
The recommended max. storage life is 12 month when stored under normal conditions.
