non discoloring stabilizer Phenolic Antioxidant irganox 245 primanox 245

Quick Detail :

AO245 - 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 .

Description :

1. Name : AO245
2. Chemical name : benzenepropanoicacid , 3 - ( 1 , 1 - dimethylethyl )  – 4 – hydroxyl – 5 – methyl - , 1 , 2 - ethanediy
3. CAS No . : 36443 - 68 - 2

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 245 with AO 168 is particularly noteworthy .

Guidelines for Use :

In polyolefins the concentration levels for AO 245 range between 0 . 05 % and 0 . 1 %

depending on substrate , processing conditions and long - term thermal stability

requirements . The optimum level is application specific .

AO 1076 is recommended for styrene homo - and copolymers at a concentration

level ranging from 0 . 05 to 0 . 5 % .

Concentration levels of AO 245 in hot melt adhesives range from 0 . 1 % to 0 . 5 % .

Applications :

AO 245 can be applied in polystyrene, especially in ABS , MBS , and SBR AO245 play a good performance .
