عوامل ضدپیری
Accelerator DCBS (N,N-Dicyclohexyl-2-Benzothiazolesulfenamide)
N,N-Dicyclohexyl-2-benzothiazolesulfenamide (DCBS) is a delayed-action sulfenamide accelerator offering the longest scorch time among commercial benzothiazole sulfenamides. It is the preferred accelerator for thick-section tire components and belt compounds containing insoluble sulfur, where extended processing safety is critical. DCBS delivers a high crosslink density and excellent reversion resistance upon vulcanization.

Accelerator DPG (Diphenylguanidine)
Diphenylguanidine (DPG) is a slow-acting secondary accelerator widely used in combination with primary sulfenamide or thiazole accelerators to boost vulcanization rate and crosslink density. It is particularly valuable in silica-filled tire compounds as it acts as an activator for the silane coupling agent reaction, improving filler-polymer bonding. DPG provides good scorch safety and excellent aging resistance in cured compounds.

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.
