Product Application
It can act as an intermediate for manufacturing antioxidants, stabilizers and UV absorbers. Functioning both as an antioxidant and UV absorber itself, it is a key precursor for numerous light stabilizers and antioxidant products.
Its applicable products cover Antioxidant 168, Antioxidant P-EPQ, Light Stabilizer 120, UV-327 and UV-320 UV absorbers, as well as activators for reclaimed rubber. It can also be developed into synthetic intermediates and plasticizers, and serves as a primary raw material for producing phosphite-type antioxidants.
