Send EmailZinc Dimethyl Dithiocarbamate, Accelerator ZDMC, PZ-80, Rubber Accelerant ZDMC, ZDMC, ZDMC-80, ZDMC80, 137-30-4
CAS No: 137-30-4 Chemical Formula: C₆H₁₂N₂S₄Zn Appearance: White to creamy powder or granules Packaging Type: Typically 25 kg bags or PD masterbatch form
| Property | Value / Description |
|---|---|
| Active Content (%) | ~80 (in masterbatch form) |
| Melting Point | > 180 °C |
| Nitrosamine Risk | Low |
| Dispersion | High (in PD form) |
| Toxicity | Low |
| Sector | Description |
|---|---|
| Latex Products | Enables fast curing at low temperatures in gloves, catheters, balloons. |
| Natural Rubber | Used as a secondary accelerator for rapid vulcanization. |
| Synthetic Rubber | Plays a supporting role in SBR, NBR systems. |
| Agrochemicals | Used in certain fungicide formulations. |
| Adhesives | Applied in specialized "Medicine Glue" formulations. |
Effective at low temperatures: Ideal for latex systems requiring fast curing.
Clean formulation: Nitrosamine-free, preferred in medical-grade products.
High dispersion: PD form ensures homogeneous mixing.
High efficiency at low dosage: Works well as a secondary accelerator.
May degrade at high temperatures — process temperature must be controlled.
Can react with metal ions — stability testing in formulations is recommended.
| Sector | ZDMC Suitability | TBBS Suitability | Notes |
|---|---|---|---|
| Natural Rubber | ✅ High | ✅ Medium | ZDMC acts fast at low temp; TBBS offers delayed vulcanization. |
| Synthetic Rubber (SBR, NBR) | ✅ Medium | ✅ High | TBBS performs strongly in SBR/NBR systems. |
| Latex Systems | ✅ High | ❌ Not suitable | ZDMC preferred for low nitrosamine risk. |
| Automotive Tires | ❌ Low | ✅ High | TBBS provides superior mechanical strength. |
| Medical Products | ✅ High | ❌ Not suitable | ZDMC ideal for low toxicity and fast curing. |
| General Industrial Rubber | ✅ Medium | ✅ High | Both usable depending on formulation. |
| Agrochemicals | ✅ (as fungicide) | ❌ | ZDMC used in some pesticide blends. |
| Fire Hose, Gaskets etc. | ✅ Medium | ✅ High | TBBS preferred for durability; ZDMC as secondary accelerator. |
| Justification Type | Description |
|---|---|
| Nitrosamine Risk | ZDMC is nitrosamine-free, making it mandatory in medical and food-contact rubber. |
| Low-Temperature Curing | Essential in latex systems requiring fast vulcanization at low temperatures. |
| High Dispersion (PD Form) | PD form ensures process stability and is standardized in some production lines. |
| Regulatory Compliance | EU and FDA regulations mandate nitrosamine-free accelerators in specific applications. |
| Medical & Hygiene Products | Required by certification and customer specs in sensitive applications. |
| Medicine Glue Formulations | The only suitable accelerator in certain adhesive systems — no alternatives. |
ZDEC, ZDBC, ZMBT may be used in some systems, but:
Curing speed is lower
Nitrosamine risk is higher
Dispersion and process compatibility are limited

ZDEC: Ultra-fast curing, ideal for low-temp systems. Low nitrosamine risk.
ZDBC: Good aging resistance, slower curing.
ZMBT: Broad curing range, versatile in technical rubber.
TBBS: Delayed vulcanization, high mechanical strength — essential in automotive.
