    Introduction:

     

    Antioxidant 626, soluble in organic solvents like toluene, dichloromethane, and slightly soluble in alcohols, but insoluble in water. Flash point: 168°C, kindling point: 421°C, lower limit concentration of dust explosion: 0.12Kg/m3.

     

    Feature

     

    Antioxidant 626 is a kind of high performance solid organic phosphite antioxidant, which has a good protective effect on the color and luster of the polymer, and is superior to other phosphite esters. It is generally not used alone, and is often used in combination with antioxidant 1010 and other phenolic main antioxidants to improve the thermal stability of the polymer processing process.Combined with phenolic antioxidants,626 is widely used in PE, PP, PS, polyamide, polycarbonate, ABS and other polymer materials.

     

    Application
       

    High-effective solid phosphite ester antioxidant 626 (CAS No.: 26741-53-7 ) , which is superior to other phosphite ester in the effective protection of polymers’ color. It is often blended with phenolic principal antioxidant (such as Antioxidant 1010) to prepare composite antioxidant which improves the thermo-stability of polymer processing, thus making it widely applied in PE, PP, PS, PA, PC, ABS and many other polymer materials. Reference dosage at 0.1%-0.3%.
