Chemical Name:Bis (2, 4-di-tert-butylphenyl) pentaerythritol diphosphite
Molecular Formula:C₃₃H₅₀O₆P₂
Molecular Weight: 604
CAS No.:26741-53-7
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.
Storage
Keep container tightly closed in a cool, well-ventilated place.
The recommended max. storage life is 12 month when stored under normal conditions.
