CAS No.: 26780-96-1

H.S. Code: 3812 30 2000

Main applications:

• Slightly staining non-blooming antioxidant in the production of rubber compounds for tyres, tyres retreads and heavily stressed technical rubber goods (tubes, buffers, insulating electric wires & cables, conveyor and transmission belts, steam hoses, break linings, oil seals, profiles, boots and footwear soles and heels) based on NR, IR, SBR, NBR and polybutadiene. 0.5 - 3.0 phr loadings enhance their flex life and provide long-time thermal-oxidative protection.
• Excellent antiozonant for CR, partially replaces para-phenylenediamine (PPDA) antiozonants.
• Inhibitor of oxidation catalyzed by copper and manganese.

Other applications:

• Peroxide cure (0.25 - 1.0 phr) of EPR/EPDM and NBR compounds.
• Antioxidant protection of latexes.
