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.

Accelerator ZBDC (Zinc Dibutyldithiocarbamate)
Zinc Dibutyldithiocarbamate (ZBDC) is an ultra-fast dithiocarbamate accelerator used as a secondary or primary accelerator in natural and synthetic rubber systems. It provides an extremely fast cure rate at low temperatures, making it ideal for room-temperature vulcanization and latex applications. ZBDC is also used as an antioxidant synergist and heat-aging stabilizer in rubber compounds.

Accelerator ZDEC (Zinc Diethyldithiocarbamate)
Zinc Diethyldithiocarbamate (ZDEC) is an ultra-fast primary dithiocarbamate accelerator widely used in latex and dry rubber vulcanization. It is particularly favored in latex systems for surgical gloves, condoms, and medical dipped goods where low extractable nitrosamine levels are required. ZDEC provides a short induction period and fast crosslink formation, delivering high modulus and tensile strength.

Accelerator ZDMC (Zinc Dimethyldithiocarbamate)
Zinc Dimethyldithiocarbamate (ZDMC) is one of the most reactive dithiocarbamate accelerators, providing extremely fast vulcanization at low temperatures. It is extensively used as a booster accelerator in thiazole or sulfenamide-based systems and as a primary accelerator in latex applications. ZDMC is also a widely used agricultural fungicide, so it benefits from well-established manufacturing quality standards.

Accelerator ZMBT (Zinc 2-Mercaptobenzothiazole)
Zinc 2-Mercaptobenzothiazole (ZMBT) is the zinc salt of MBT, offering faster vulcanization than MBT with reduced scorching tendency. It is a semi-safe accelerator used primarily in latex systems and as a secondary accelerator in dry rubber compounds. ZMBT provides good aging resistance and is widely used in NR, SBR, and NBR compounds for footwear, industrial goods, and latex dipped products.

Antioxidant 6PPD (N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine)
6PPD is the world's most widely used rubber antidegradant, providing outstanding protection against ozone, flex cracking, and dynamic fatigue in tire compounds. It functions by scavenging ozone and reacting with peroxy radicals, effectively preventing the oxidative degradation of diene rubbers. 6PPD is an industry standard antiozonant in tire treads, sidewalls, and general dynamic rubber applications.

Antioxidant IPPD (N-Isopropyl-N'-phenyl-p-phenylenediamine)
N-Isopropyl-N'-phenyl-p-phenylenediamine (IPPD) is a p-phenylenediamine antidegradant that offers excellent protection against ozone, oxygen, flex cracking, and heat aging in natural and synthetic diene rubber compounds. IPPD provides slightly more volatile protection than 6PPD but delivers superior antifatigue properties and is often used as a complement or alternative to 6PPD in tire and industrial rubber formulations.

Antioxidant MBI (2-Mercaptobenzimidazole)
2-Mercaptobenzimidazole (MBI) is a non-staining, non-discoloring antioxidant that provides good protection against thermal oxidation and catalytic degradation induced by heavy metal ions. It is widely used in light-colored and white rubber articles where staining must be avoided, and serves as an effective copper-ion deactivator. MBI is often blended with other antioxidants for synergistic protection in EPDM, NBR, and natural rubber.
