Product Name:Bis(2,4-di-tert-butylphenyl)phenyl phosphonite
English Name:Bis(2,4-di-tert-butylphenyl)phenyl phosphonite
CAS No.:70146-21-3
Aliases:Antioxidant phosphonite, Bis(2,4-di-tert-butylphenyl)phenyl phosphonite ester
Molecular Formula:C34H47O2P
Physical Properties:White or off-white crystalline powder, molecular weight 518.71. Insoluble in water; soluble in organic solvents such as toluene, acetone, and alcohols. Good thermal stability and hydrolysis resistance. Melting point approximately 85~88°C and decomposition temperature above 300°C.
Uses:It is a phosphonite-type secondary antioxidant widely used in processing stabilization systems for polyethylene, polypropylene, polystyrene, ABS, and other polymer materials. It effectively inhibits thermo-oxidative degradation of polymers during high-temperature processing and service. It exhibits a remarkable synergistic effect when combined with hindered phenolic primary antioxidants. It is also applicable to the anti-aging treatment of rubber and elastomers.
Technical Specifications:
White or off-white crystalline powder appearance
Melting point range: 85~88°C
Volatile content ≤ 0.5%
Acid value ≤ 0.5 mg KOH/g
Purity (HPLC) ≥ 98.0%
