Ultranox 626;Bis(2,4-di-tert-butylphenyl) pentaerythritol diphosphite; 3,9-Bis(2,4-bis(1,1-dimethylethyl)phenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro(5.5)undecane; ADK Stab PEP 24; Mark PEP 24
Yes
Non-hazardous
12 MT for net 20/25 kg bag or 10 MT for net 20/25 kg carton
Specification
Item | Specification |
Appearance | White crystalline powder |
Purity | 95.0% min |
Melting point | 170.0-180.0°C min |
Volatiles | 1.0% max |
Acid value | 1.0mgKOH/g max |
Free 2,4-di-t-butylphenyl | 1.0% max |
Application
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 Antioxidant 1010) to prepare composite antioxidant which improves the thermo-stability of polymer processing, thus making it widely applied in PE, PET,PP, PS, PA, PC, ABS and many other polymer materials. Reference dosage at 0.1%-0.3%。
Packing and Storage
Packing In 20 or 25kgs net plastic bag into Aluminum bag with nitrogen protection into carton.
Storage Keep container tightly closed. Away from moisture ad heat to avoid hydrolysis.
Safety Information
Non-hazardous for air, sea and road freight.
