English name: Bis (2.4-di-t-butylphenyl) Pentaerythritol Diphosphite

Molecular formula: C33H50O6P2

Molecular weight: 604.69

CAS No .: 26741-53-7

Quality Standard:



ZX-626 improves the stability of the polymer in the formulation, production use process, so that less polymer degradation during processing.

In many applications, it can improve the performance of the polymer, the low input can form a more efficient formula, which has a higher phosphorus content than other equivalent phosphite antioxidants; it can improve the light stability of the polymer, It can also be used as a synergist for light-resistant stabilizers such as benzophenone benzotriazole.

ZX-626 is a high-performance solid organic phosphite antioxidant. It has a good protection for the color of the polymer. It is superior to other phosphites. It is generally used alone, is often resistant to phenols such as ZX-1010. The combined use of oxygen agent can improve the thermal stability of polymer processing. This product is widely used in polymer materials such as PE, PP, PS, polyamide, polycarbonate, ABS after compounding with phenolic antioxidant.

Product packaging:

The cardboard drum (box) is lined with plastic bags, the net weight of each drum (box) is 25Kg. according to customer requirements.
