N,N’-Diphenylguanidine (DPG) is a vulcanization accelerator for natural and synthetic rubbers. Furthermore, N,N’-Diphenylguanidine (DPG) a secondary accelerator, activating Thiazoles (MBT, MBTS), Thiurams (TMTM, TMTD) or Sulfenamide (CBTS) in NR (0.1-0.5phr), SBR (0.15 – 0.75phr) and NBR (0.1-0,5phr) applications. In conjunction with Sulphur and TMTM, N,N’-Diphenylguanidine (DPG) acts as plasticizer on chloroprene rubber. N,N’-Diphenylguanidine (DPG) provides a good scorch and storage stability. Other applications include primary material for standardizing acids and the production of ultramarine blue pigment. Due to discoloration, N,N’-Diphenylguanidine (DPG) is generally for dark or black coloured rubber products.
