China Star Materials Octylated diphenylamine (Antioxidant OD)

China Star Materials Octylated diphenylamine (Antioxidant OD) is antioxidant for NR, SBR, NBR and CR. It has good protective character to heat, oxygen, flexing and crazing, and is efficient to rubber whether used together with carbon black. It has obvious thermal brittleness resistance in CR, and can increase its protective character to ozone aging.

Chemical Family: Amines

Functions: Antioxidant, Primary Antioxidant

Compatible Polymers & Resins: Chloroprene Rubber (CR), Natural Rubbers (NR), Nitrile Butadiene Rubber (NBR), Styrene Butadiene Rubber (SBR)

Features: Crazing Resistant, Heat Resistance, Oxidation Resistant
