ZDBC Manufacturers in China: Key Suppliers Overview (2026)
ZDBC Manufacturers in China
ZDBC (Zinc Dibutyl Dithiocarbamate) is a relatively small-volume rubber accelerator in the dithiocarbamate family. Unlike high-volume accelerators such as CBS or MBTS, ZDBC is produced by a limited number of specialized manufacturers in China. This article provides a factual overview of the key ZDBC suppliers.
Overview
ZDBC is a niche product compared to mainstream accelerators. While China dominates global rubber chemical production, ZDBC manufacturing is concentrated among a few specialized companies. Below are the known ZDBC manufacturers based on industry knowledge and publicly available information.
Key ZDBC Manufacturers
1. Hebi Uhoo
Location: Hebi, Henan Province Specialty: Dithiocarbamate accelerators including ZDBC, ZDEC, ZDMC
Hebi Uhoo is a well-known producer of dithiocarbamate accelerators in China. They have established a reputation for consistent quality in the ZDBC market and supply to both domestic and export customers.
Products: ZDBC (powder and granules), ZDEC, ZDMC, other dithiocarbamates
2. Willing Chemical
Location: Puyang, Henan Province Specialty: Full range of rubber accelerators including dithiocarbamates
Willing Chemical (Puyang Willing Chemicals Co., Ltd.) is a medium-to-large scale rubber accelerator manufacturer. They produce ZDBC as part of a comprehensive accelerator portfolio and serve customers in tire, industrial rubber, and footwear sectors.
Products: ZDBC, ZDEC, TMTD, CBS, MBTS, and other accelerators
3. Liyuan New Material
Location: China Specialty: Rubber chemicals and additives
Liyuan New Material is an emerging player in the rubber chemical space, offering ZDBC among their product range. They focus on consistent quality and competitive pricing.

Dithiocarbamate Manufacturers in China by Product Type
Why So Few ZDBC Manufacturers?
ZDBC is a lower-volume product compared to mainstream accelerators like CBS (used heavily in tires) or ZDEC (used heavily in latex). This is due to:
Tire industry prefers CBS/TBBS/DCBS — Sulfenamides dominate tire manufacturing
Latex industry prefers ZDEC — Better low-temperature activity
ZDBC is a specialty niche — Used where heat resistance and scorch safety balance is needed
Limited application scope — Primarily in industrial rubber goods, dark-colored products, and specialty tire compounds
As a result, there are fewer dedicated ZDBC production lines, and most ZDBC is manufactured as a secondary product alongside higher-volume dithiocarbamates.
