Sinanox® 80 Usage

Antioxidant 80 is a semi-hindered phenolic antioxidant with good compatibility, low volatility, good thermal stability and high antioxidant efficiency. It can be hydrogen bonded with thioesters to produce an excellent synergistic effect. The antioxidant effect is rapid, inhibiting nitrogen oxide colouration and preventing extraction and migration losses. Hydrogen bonding with rubber molecules improves rubber damping properties and increases rubber tensile strength. Suitable for plastics, rubber and adhesives, especially for thermoplastic polyurethane, polyphenylene sulfide, polyamide and polyformaldehyde. The general dosage is 0.5-1.0%.
