Product Description

ANTIOXIDANT 168

  Chemical Name:  Tris-(2.4-di-t-butylphenyl)- phosphite

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 powder or grain		Assay:	≥99%
Melting Range:	183-187ºC		Acid value:	≤0.2mg KOH/g
Light Transmittance:	425nm≥98% 500nm≥98%		Volatiles:	≤0. 3%
Hydrolytic stability	Pass	2,4-t-butyl-phenol		≤0.2%

Solubility: (At 20ºCg/100ml solvent)

Water	Insoluble	Acetone	1
Benzene	34	Ethyl Acetate	4

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 in bags or cartons, or as required

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

Period of Validity:  About 2 years
