CAS No . 2082 - 79 - 3 Phenolic Antioxidant irganox 1076 for PC /
PE / Additives
Quick Detail :
AO1076 - a sterically hindered phenolic antioxidant - is a highly
effective , non discoloring stabilizer for organic substrates such
as plastics , synthetic fibers , elastomers , adhesives , waxes ,
oils and fats . It protects these substrates against
thermo-oxidative degradation .
- Name : AO1076
- Chemical name : Octadecyl 3 - ( 3 , 5 - di - tert - butyl - 4 -
hydroxyphenyl ) propionate
- CAS No . : 2082 - 79 - 3
The product can be used in combination with other additives such as
co-stabilizers ( e . g . thioethers , phosphites , phosphonites ) ,
light stabilizers and other functional stabilizers . The
effectiveness of the blends of AO 1076 with AO 168 , AO 1010 is
particularly noteworthy .
Guidelines for Use :
500 ppm - 2000 ppm of AO 1076 provide long-term thermal stability
to the polymer .
Concentrations up to several percent can be used depending on the
substrate and the requirements of the end application .
In polyolefins the concentration levels for AO 1076 range between 0
. 1 % and 0 . 4 %
depending on substrate , processing conditions and long - term
requirements . The optimum level is application specific .
AO 1076 is recommended for styrene homo - and copolymers at a
level ranging from 0 . 1 to 0 . 3 % .
Concentration levels of AO 1076 in hot melt adhesives range from 0
. 2 % to 1 % and
in synthetic tackifier resins between 0 . 1 % and 0 . 5 % .
Extensive performance data of AO 1076 in various organic polymers
applications are available upon request .
AO 1076 can be applied in polyolefins such as polyethylene ,
polybutene - 1 as well as in other polymers such as engineering
plastics , styrene homo - and copolymers , polyurethanes ,
elastomers , adhesives , and other organic substrates .
