CHEMICAL COMPONENT

COMPONENT: Bis(2,4-di-tert-butylphenyl) pentaerythritol diphosphite 

CAS: 154862-43-8

FORMULA: C53H58O6P2

M.W.: 853

Catalyst

SPECIFICATION ANPHYSICAL PROPERTIES:

APPEARANCE: OFF WHITE POWDER OR GRANULAR

MELTING POINT: 225ºCMIN

FEATURES 

1. AN 948 is high molecular weight phosphite antioxidants with excellent thermal stability and

 unsurpassed hydrolytic stability.
2. Excellent melt flow ,color protection and thermal degradation during high temperature processing 

or application conditions, such as transportation vehicles, dishwashers toasters and dryers.
3. AN 948 has excellent hydrolytic stability in polymer and atmosphere,it remains granular and 

free flowing powder even exposed to extremely elevated moisture conditions.

APPLICATIONS

1.PP, in polypropylene systems that use only a phosphite as process stabilizer ,  AN 948 could provide high efficiency.
2.PE, low dosage and excellent color and melt flow stability in both HDPE and LDPE.
3.PC,  AN 948 could withstand high processing temperatures , where most phosphite antioxidants degrade or volatilize , 

   benefiting from its high molecular weight and low volatility.
