In the globally regulated rubber manufacturing sector, mitigating carcinogenic health risks on the factory floor is now an operational mandate rather than an elective preference. Zinc Dibenzyl Dithiocarbamate (universally recognized in B2B chemical procurement as ZBEC or ZBDC) stands as the ultimate non-regulated, safe dithiocarbamate ultra-accelerator. Chemically registered as CAS No. 14726-36-4, ZBEC effectively replaces traditional accelerators like ZDEC or ZDBC. Because its dibenzyl molecular structure does not generate volatile, hazardous N-nitrosamines during compounding or vulcanization, it provides compounding engineers with a pristine compliance profile for food-contact items, medical articles, and high-performance latex applications without compromising curing kinetics.

Why Choose Our ZBEC (ZBDC) Accelerator?
- ✓ Safe, Non-Nitrosamine Curing Alternative: Unlike conventional dithiocarbamates, ZBEC generates non-volatile secondary amines that do not convert into toxic, regulated nitrosamines, completely satisfying strict German TRGS 552 workplace regulations.
- ✓ Extended Scorch Safety Margins: Among standard dithiocarbamates, ZBEC offers uniquely enhanced processing safety and lower premature scorch risks at typical mixing temperatures, outperforming both ZDEC and TMTD.
- ✓ Exceptional Low-Temperature Activity: Functioning effectively as a fast primary or high-efficiency secondary ultra-accelerator, it triggers rapid cross-linking in latex or dry rubber matrices starting at lower thermal activation points.
Primary Applications
Accelerator ZBEC (ZBDC) is highly suitable for Natural Rubber (NR), EPDM, Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), and synthetic latex processing systems:
Medical & Food-Contact Items
Extensively formulated inside high-purity medical rubber seals, baby bottle nipples, protective examination gloves, and food-grade packaging lines.
EPDM Profiles & Weatherstripping
An ideal choice for continuous vulcanized automotive window profiles, sponge extrusions, and heavy industrial building gaskets requiring swift cure lines.
Transparent Latex Goods
Highly selected for premium dipped latex films, translucent medical tubing, and delicate rubber threads where non-staining, ultra-clear aesthetics are key.
⚠ Storage & Handling Guidelines
Maintaining correct warehouse climate parameters is vital to maintain the active purity and performance parameters of Accelerator ZBEC (ZBDC). Because dithiocarbamate compounds are sensitive to continuous elevated heat and high humidity levels, following specialized store patterns helps protect your chemical stocks.
- • Warehouse Climate Control: Keep the chemical stock packages allocated inside cool, well-ventilated, and completely dry warehouse environments. Ensure storage points stay isolated from direct solar exposure, steam lines, or localized hot processing machinery.
- • Moisture and Hardening Prevention: Keep all bags tightly sealed until active dry weighing takes place. Refrain from high multiple pallet layering to completely eliminate mass lump-caking hazards during sustained high summer thermal periods.
- • Shelf Life Strategy: Under clean, temperature-controlled sealed environments, our industrial ZBEC products possess a certified shelf life of 24 months from the manufacturing date. Emphasizing a continuous First-In, First-Out (FIFO) pipeline is highly recommended.
