1222 is a phenolic antioxidant containing phosphorus. It is a highly efficient, non discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fars. It protects these substrates against thermooxidative degradation. It is odorless, stable to light and has excellent color retention. It has good compatibility with most substrates and high resistance to extraction.

SPECIFICATIONS

Chemical Name     Diethyl((3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl)methyl) phosphonate

CAS No.           976-56-7

Structure        Antioxidant 1222

Molecular Weight   356

APPLICATIONS

1222 is particularly suitable for use in polyester fibers, acetal homo- and copolymers. It protects polyurethanes against oxidative degradation.

FEATURES/BENEFITS

1222 effectively protects synthetic fibers against photochemical and thermooxidative degradation, in use and during manufacture and processing. To be fully effective, it should be added after transesterification. It is highly extraction resistant, especially when added to the polycondensates under the recommended conditions. It can be used alone or in combinations with other SANOX stabilizers and co-stabilizers.
