Main applications: 

Main applications:

  • Secondary vulcanization accelerator, it activates 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. With bitter taste, not suitable for products connected with foodstuffs. Due to discoloration it is generally used for dark or black color products (silica containing tyres, mechanical goods, hard rubber products, footwear, adhesives, condoms and diaphragms, rubber gloves, medical devices, renal dialysis equipment, rubber in elasticized undergarments and clothing, rubber pillows, sponges, toys). Provides good scorch and storage stability;
  • Acts as plasticizer on chloroprene rubber in conjunction with sulfur and TMTM.

Secondary applications: Primary material for standardizing acids
