What is Antioxidant TNPP?

Tris(nonylphenyl) phosphite (TNPP) is an antioxidant that is majorly used as a stabilizer to improve the performance of polyethylene by decomposing the hydroperoxides. It can also be used to enhance the thermal stability by extending the polymeric chains.

Applicaton

TNPP in combination with irganox is used to protect polyamide 6 (PA6) from oxidative degradation during the preparation of flame retardant nanocomposites. TNPP can be used as a stabilizer that prevents the molecular weight reduction and increases the tensile strength of the composite.[4] It can also be used as a chain extender to improve the polymeric viscosity during the melt-blending of poly(hydroxybutyrate-co-hydroxyvalerate) based clay nanocomposites which find potential application as packaging materials.
