In high-speed rubber molding, continuous extrusion, and dipped latex manufacturing, achieving rapid cross-linking at moderate curing temperatures is critical for maximizing throughput. Rubber Accelerator ZDEC (widely known globally as Accelerator EZ or ZDC) serves as a premier ultra-fast dithiocarbamate accelerator. Chemically defined as Zinc Diethyldithiocarbamate (CAS No. 14324-55-1), ZDEC provides powerful curing activity in Natural Rubber (NR), synthetic elastomers, and aqueous latex dispersions. In addition to functioning as a standalone primary accelerator in low-temperature cures, it acts as a potent secondary booster for thiazole and sulfenamide systems while imparting mild antioxidant protection against heat aging.

Why Choose Our ZDEC (EZ) Accelerator?
- ✓ Ultra-Fast Low-Temperature Curing: Initiates rapid cross-linking at temperatures as low as 100°C–120°C, making it ideal for thin-walled molded goods, hot-air continuous vulcanization, and delicate latex films.
- ✓ Non-Staining, Non-Discoloring & Odorless: Leaves zero surface staining or contact discoloration, preserving the aesthetic purity of white, transparent, and brightly colored elastomer articles.
- ✓ High Latex Stability & Secondary Boosting: Disperses cleanly into aqueous surfactant slurries without thickening or destabilizing natural/synthetic latex compounds, while acting as a powerful secondary activator for MBT, MBTS, and CBS.
Primary Applications
Accelerator ZDEC (EZ) is widely formulated into Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), Butyl Rubber (IIR), EPDM, and aqueous latex systems:
Dipped Latex & Foam Products
An industry benchmark for surgical and household gloves, balloons, condoms, catheters, elastic threads, and molded natural or synthetic latex foams.
Wire, Cable & Extruded Profiles
Ideal for continuous vulcanization (CV) wire and cable insulation jackets, EPDM automotive weatherstripping, and rubberized fabric coatings.
White & Food-Contact Rubber Goods
Extensively used in bright-colored athletic footwear soles, pharmaceutical stoppers, food-grade seals, and self-curing adhesive cements.
Quality Assurance & Global Compliance
As a leading global partner in industrial chemical manufacturing, we understand that raw material purity, particle fineness, and strict regulatory tracking directly safeguard your production line metrics. Our advanced manufacturing facilities maintain rigorous quality configurations to ensure total compliance and confidence across all international markets:
- Advanced Laboratory Quality Control: Every commercial batch of our Accelerator ZDEC (EZ) passes through extensive laboratory verification protocols—including capillary melting range testing, complexometric zinc assay titration, and ultra-fine 325-mesh sieve residue screening—ensuring smooth ball-mill dispersion for latex dipping and zero pinholes in thin films.
- Comprehensive International Regulatory Compliance: We maintain a highly proactive approach to global chemical governance. All export shipments are systematically backed by complete regulatory documentation, including up-to-date, comprehensive multilingual GHS Safety Data Sheets (SDS), detailed Certificates of Analysis (CoA), and official tracking credentials fully matching EU REACH and US TSCA parameters.
- Optimized Packaging & Workspace Safety: To lower material handling loss and eliminate airborne chemical dust cross-contamination on your factory floor, we offer tailored logistics configurations. This includes standard multi-wall moisture-resistant kraft paper bags (25kg) lined with protective PE film, bulk jumbo supersacks (FIBCs), and dust-free oiled granule grades suited for automated dosing systems.
⚠ Storage & Handling Guidelines
Maintaining correct climate-controlled conditions is essential to protect the fine particle flowability and active curing potency of Accelerator ZDEC. While chemically stable under normal warehouse conditions, prolonged exposure to moisture or high heat can induce powder agglomeration.
- • Temperature & Humidity Controls: Store the chemical inside a completely dry, cool, and well-ventilated dedicated warehouse where ambient temperatures remain below 35°C. Keep storage racks isolated from direct solar radiation, steam pipes, heating vents, and acidic raw materials.
- • Sealing & Stacking Management: Keep all inner PE liners and outer kraft bags tightly sealed until immediate compounding or ball-milling use. Avoid excessive pallet double-stacking to prevent physical compaction.
- • Shelf Life & Rotation: Under proper cool, shaded warehouse conditions, our premium ZDEC (EZ) exhibits a certified shelf life of 24 months from the date of manufacture. A strict First-In, First-Out (FIFO) inventory rotation cycle is strongly recommended.
