Product Name:Bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite
English Name:Bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite
CAS No.:26741-53-7
Aliases:Antioxidant 626, 3,9-bis(2,4-di-tert-butylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane, Irgafos 126, Ultranox 626
Molecular Formula:C33H50O6P2
Physical Properties:White crystalline powder. Melting point: 160-175°C. Insoluble in water; soluble in organic solvents such as toluene, dichloromethane, and chloroform. Phosphorus content: approx. 10.2%. Good hydrolysis resistance.
Uses:It is a phosphite-type secondary antioxidant. When used in combination with hindered phenol primary antioxidants (e.g., Irganox 1010, 1076), it significantly improves the thermal stability and color stability of polyolefins such as polypropylene and polyethylene during processing and service life. Suitable for polyolefin products including films, injection-molded parts, and fibers, as well as engineering plastics and elastomers.
Technical Specifications:
Appearance: white crystalline powder
Melting point: 160-175°C
Phosphorus content: approx. 10.2%
Volatile content: ≤0.5%
Solubility: insoluble in water; soluble in organic solvents such as toluene, dichloromethane, and chloroform
