• Product description :

  Chemical name:Octylated diphenylamine
  Structural formula:
  
  Molecular formula: C₂₀H₂₇N
  Molecular weight: 281
  Properties: Light brown powder or granules. Melting point ≥75°C. It is soluble in benzene, dichlorethane, carbon disulfide, acetone and gasoline; insoluble in water.
  Functions: 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. It is mainly used in tyres, tube tyres, cables, rubber tapes, rubber pipes, filling rings, etc. Normal dosage is 0.5-2 phr.
