In high-throughput industrial rubber production and delicate latex dipping operations, minimizing cure cycles while maintaining robust mechanical outputs is a critical operational goal. Zinc Dimethyl Dithiocarbamate (universally recognized in B2B chemical procurement markets as ZDMC or PZ) stands as one of the fastest and most reliable dithiocarbamate-class ultra-accelerators available. Chemically registered under CAS No. 137-30-4, ZDMC possesses exceptional low-temperature activation capabilities. It effectively serves as a highly active primary or secondary booster across both natural and synthetic elastomers, providing compounding engineers with a predictable pathway to achieve high cross-linking density and superior physical resilience fields.

Why Choose Our ZDMC (PZ) Accelerator?
- ✓ Rapid Curing and Low-Temperature Activity: ZDMC provides incredibly fast vulcanization rates at relatively low temperatures, reducing thermal energy costs and accelerating cycle times in casting and molding operations.
- ✓ Non-Staining and Excellent Aging Resistance: It leaves light-colored and transparent rubber components visually pure, without inducing color contact staining, while granting formidable antioxidant stability.
- ✓ Exceptional Secondary Booster Efficacy: When formulated in minor percentages alongside thiazoles or sulfenamides, it dramatically increases cross-linking density and structural tensile properties in dry rubber batches.
Primary Applications
Accelerator ZDMC (PZ) is universally formulated within Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), EPDM, and diverse synthetic latex dispersion systems:
Latex Dipped Products
Extensively selected for medical-grade dipped films, household latex gloves, surgical examination protections, and premium flexible rubber threads.
Medical & Food-Grade Sundries
An optimal choice for translucent medical seals, food-handling gaskets, laboratory tubing, and technical consumer goods demanding high sanitization protocols.
Industrial Proofing & Fabrics
Selected for rubberized protective textiles, self-vulcanizing adhesive cements, elastic sheet backing formulations, and cold-cured technical rubbers.
⚠ Storage & Handling Guidelines
Maintaining correct warehouse climate parameters is vital to maintain the active purity and performance parameters of Accelerator ZDMC (PZ). Because dithiocarbamate compounds are sensitive to continuous elevated heat, severe moisture ingress, and acidic atmospheres, following specialized store patterns helps protect your compounding stocks.
- • Warehouse Climate Control: Keep the chemical stock packages allocated inside cool, thoroughly ventilated, and completely dry warehouse environments. Ensure storage points stay isolated from direct solar exposure, dynamic steam ducts, or high-temperature processing vents.
- • Sealing & Hardening Preventions: Keep all paper bags tightly sealed until active dry weighing takes place. Refrain from configuring heavy multiple pallet layers to avoid mass lump-caking hazards over high summer thermal periods due to ZDMC’s ultra-fine particle arrangement.
- • Shelf Life Strategy: Under clean, temperature-controlled sealed environments, our industrial ZDMC 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.
