Applications

Antioxidant 245 is a stereo-blocked phenolic antioxidant especially suitable for organic polymers.It can protect the material from thermal oxidation degradation in the process of production, processing and final use. 

Antioxidant 245 is very effective in styrene polymers, especially for HIPS, ABS, MBS, SB and


SBR latex and POM monomer and copolymer, can also be used as a stabilizer in polyurethane, polyamide, thermoplastic polyester, PVC, etc.

Antioxidant 245 has odorless, low volatility, high color fastness and high extraction resistance.It can be mixed with other additives, such as auxiliary antioxidants (sulfur ether, phosphite ester), light stabilizers and antistatic agents.
