Accelerator DTU (Diethylthiourea)
Diethylthiourea (DTU) is a thiourea-type accelerator primarily used for the vulcanization of polychloroprene (neoprene) and chlorosulfonated polyethylene (CSM) rubbers. It provides fast cure rates without requiring sulfur and produces excellent heat and ozone resistance in the cured compound. DTU is often used in combination with magnesium oxide and zinc oxide for optimized cure systems in CR-based cables and industrial goods.
