Ionol K65 is a proprietary hindered phenolic antioxidant formulation used as an oxidation inhibitor and thermal stabilizer for polymers, synthetic rubbers, engineering plastics, lubricants, adhesives, elastomers and specialty chemical formulations. It effectively suppresses thermo-oxidative degradation during polymer processing, extrusion, molding and long-term service, improving color stability and extending product lifetime. It is also used as an intermediate additive package for specialty materials research.
