In high-efficiency industrial compounding lines, material incorporation velocity and strict environmental safety controls define competitive output. Pre-Dispersed Rubber Accelerator ZDBC (also known as BZ) represents a premium, polymer-bound masterbatch solution. Chemically built upon Zinc dibutyldithiocarbamate (CAS No. 136-23-2), this masterbatch features an elastomer matrix binder that locks in the active chemical crystals. By converting fine dust-prone chemical powder into cohesive pellets, it ensures rapid incorporation during mixing cycles, completely eliminating chemical clumping and driving downstream compound homogeneity.

Why Choose Our Pre-Dispersed ZDBC (BZ)?
- ✓ Flawless Macro-Dispersion: Because raw ZDBC crystals are pre-milled and locked uniformly into a polymer binder, the pellets split effortlessly under internal shear during compounding, eliminating spotty cross-linking variations.
- ✓ Total Dust Elimination: Fine raw dithiocarbamate powder triggers severe inhalation and cross-contamination hazards. Our pre-dispersed pellets maintain a clean, safe, and dust-free factory environment compatible with modern EHS rules.
- ✓ Ultra-Fast Low-Temperature Curing: ZDBC functions as a prominent ultra-accelerator. It provides quick vulcanization at relatively low activation thresholds, making it highly effective for non-sulfur profiles or efficient vulcanization (EV) cycles.
Primary Applications
Our pre-dispersed ZDBC masterbatch is highly compatible with EPDM, NR, SBR, NBR, and transparent synthetic elastomer formulations:
EPDM Weatherstripping & Profiles
Extensively applied in continuous extrusion continuous microwave vulcanization profiles, window automotive glass runs, and dense weather seals.
Industrial Sheetings & Hoses
Perfect for light-colored industrial steam hoses, fabric-reinforced conveyor sheets, and high-purity rubber gaskets where dispersion spots ruin performance.
Clear Consumer & Latex Specialties
Widely selected for clear or white translucent elastic components, athletic footwear outsoles, and technical dipped-latex compounds requiring non-staining aesthetics.
Quality Assurance & Global Compliance
As a leading global partner in industrial chemical manufacturing, we understand that raw material purity, molecular consistency, 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 pre-dispersed ZDBC masterbatch undergoes rigorous testing—including moving die rheometer (MDR) verification curves to monitor cross-linking uniformity, active density screening, and filtration mesh testing—ensuring flawless batch-to-batch consistency.
- 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 carton boxes (25kg) lined with protective PE sheets, or custom bulk cardboard container configurations perfectly suited for automated weighing systems.
⚠ Storage & Handling Guidelines
Maintaining correct climate-controlled conditions is essential to protect the molecular performance stability of pre-dispersed masterbatches. Because polymer-bound matrices can soften under intense heat, sub-optimal warehouse conditions can cause pellets to fuse or block together.
- • Strict Temperature Controls: Store the chemical inside a completely dry, cool, and well-ventilated dedicated warehouse. Keep storage temperatures strictly below 35°C to prevent matrix nesting or consolidation. Keep away from heating vents or hot pipelines.
- • Stacking & Weight Limits: Avoid excessive structural double-stacking of pallets. Excessive weight loading can cause compaction among lower pellets, altering material handling characteristics during automatic dosing.
- • Shelf Life & Rotation: Under standard cool, shaded warehouse conditions, our premium pre-dispersed ZDBC masterbatch exhibits a certified shelf life of 12 months from the date of manufacture. A strict First-In, First-Out (FIFO) batch cycle is strongly advised to maximize production uniformity.
