Product Description

Chemical Name:  Tris-(2.4-di-t-butylphenyl) - phosphate
Molecular formula: C42H63O3P
Molecular Weight: 646
CAS: 31570-04-4
Introduction:  This product is soluble in resin and has the characteristic of low volatile, high heat resisting, pump resisting, implosion and non-discoloration. At present, it is the best processing stabitor in China.

Physical Properties:

Appearance		White to offwhite powder
Melting Range		183-187ºC
Purity		≥99%
Acid value (mg KOH/g)		≤0.3%
Light Transmittance	425nm	≥98%
	500nm	≥98%
Volatiles		≤0. 3%
Hydrolyze time (h)		≥14
2,4-t-butyl-phenol (%)		≤0.2

Applications: The product is a kind of high-effective solid phosphite ester antioxidant, which is superior to other phosphite ester in the effective protection of polymers' color. It is often blended with phenolic principal antioxidant (such as 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.

Package: Net 25KGS/two-layer PE bag in carton/drum, or as required

Storage: Because of the low performance on hydrolyzing resistance, protectionfrom moisture and heat is needed.
