Irganox® B 612

Technical Datasheet | Supplied by BASF

Discontinued : product no longer available

Irganox® B 612 is a blend of 33.3% 2,6-di-tert-butyl-4-(4,6-bis(octylthio)-1,3,5-triazin-2-ylamino) phenol and 66.7% tris(2,4-ditert-butylphenyl)phosphite. It is basically a blend of 66.7% IRGAFOX 168 and 33.3% IRGANOX 565. Acts as a processing and long-term thermal stabilizer. Maintains original melt flow and offers low color formation. Provides long-term-thermal stability. IRGAFOX 168, an organic phosphite of low volatility and particularly resistant to hydrolysis, protects the polymers which are prone to oxidation. IRGANOX 565, a hindered phenolic antioxidant, contributes synergistically to polymer stabilization during processing and provides long-term thermal stability by preventing thermo-oxidative degradation. It is compatible with styrene homo- and copolymers, polyolefin homo- and copolymer, elastomers such as BR, IR, NBR, SBS, SIS, SEBS, SBR, EPDM, and NR. Its recommended dosage is 0.3-1.0%. It is registered in Australia, Canada, China, EU, Japan, Korea, Philippines and USA.
