What Is Dithiocarbamate Salts Accelerator?
Dithiocarbamate Salts Accelerator represents a critical advancement in rubber compounding technology. These highly reactive accelerators are essential for the vulcanization of natural rubber and synthetic rubbers like SBR and BR. They function as fast-acting agents that significantly reduce processing time while ensuring uniform cross-linking throughout the rubber matrix.
For procurement specialists sourcing high-performance rubber chemicals, dithiocarbamate salts offer a distinct advantage: exceptional scorch safety combined with rapid cure rates. This balance allows manufacturers to handle materials more easily during mixing and extrusion, reducing the risk of premature curing while maintaining tight production schedules.
Common variants include Zinc Diethyldithiocarbamate (ZDEC) and Zinc Dimethyldithiocarbamate (ZDMC). These compounds are widely used in the automotive industry for sealing strips, hoses, and vibration dampeners where consistent quality and durability are non-negotiable.

Buyer Decision Checklist for Rubber Accelerators
When evaluating suppliers for dithiocarbamate salts and other rubber additives, use this checklist to mitigate risk and ensure product compatibility.
Verify Technical Consistency
- Purity Levels: Ensure active content matches your formulation specs (typically 98%+).
- Particle Size: Check mesh size distribution for optimal dispersion in rubber matrices.
- COS/REACH Compliance: Confirm all regulatory documentation is up-to-date for your region.
Evaluate Supplier Reliability
- Production Capacity: Verify annual output matches your volume requirements.
- Custom Solutions: Can they adjust active content or binder types for your specific needs?
- Export Track Record: Look for experience shipping to Europe, Americas, and Southeast Asia.
How to Choose the Right Dithiocarbamate Accelerator
Selecting the correct accelerator variant depends on your rubber type, processing equipment, and final product requirements. Here is how to make an informed decision.
ZDEC vs. ZDMC
ZDEC offers faster cure rates and better plasticity, ideal for dynamic applications. ZDMC provides excellent storage stability and is often preferred for static parts or when longer shelf life is critical.
Formulation Compatibility
Dithiocarbamates are typically used in conjunction with delayed action accelerators (like MBT or CBS) to prevent scorching. Ensure your supplier can provide technical guidance on proper synergistic blending ratios.
Dispersion Method
Consider using pre-dispersed masterbatches. They eliminate dust hazards, improve dosing accuracy, and ensure homogeneous distribution of the accelerator within the rubber compound, reducing waste and rework.
Key Industries Using Dithiocarbamate Salts
These accelerators are vital across multiple high-performance sectors. Understanding their applications helps in tailoring procurement strategies.
Automotive Sealing Strips
EPDM rubber sealing strips for doors and windows require consistent vulcanization. Dithiocarbamates ensure the rubber remains flexible over time while resisting weathering and ozone exposure.
Rail Traffic Components
Vibration dampeners, bushings, and gaskets in rail systems demand high durability. The fast cure properties of these salts help meet strict safety and longevity standards for public transport infrastructure.
Industrial Hoses & Tyres
For high-pressure hoses and tyre sidewalls, uniform cross-linking is essential to prevent failure under stress. These accelerators contribute to the structural integrity and extended service life of critical rubber components.

Frequently Asked Questions About Rubber Accelerators
Common questions from procurement buyers regarding dithiocarbamate salts and rubber chemical sourcing.
What is the difference between ZDEC and ZDMC accelerators?
ZDEC (Zinc Diethyldithiocarbamate) generally has a faster cure rate and provides better plasticity, making it suitable for dynamic applications. ZDMC (Zinc Dimethyldithiocarbamate) offers superior storage stability and is often chosen for static applications or when longer shelf life is required. Both are highly effective in natural rubber and SBR/BR blends.
Are pre-dispersed rubber chemicals safer to handle?
Yes. Pre-dispersed masterbatches significantly reduce dust generation during handling compared to raw powder forms. This improves workplace safety, reduces health risks associated with inhalation, and ensures more accurate dosing, which minimizes material waste and improves product homogeneity.
Can Actmix provide custom formulations for my rubber compound?
Absolutely. We specialize in customizing masterbatches with varying active content levels and polymer binders to match your specific formulation requirements. Our R&D team works closely with clients to develop tailored solutions that optimize performance and cost-efficiency.
What certifications do your rubber chemicals carry?
Our facility is certified under IATF 16949 (automotive quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety). All products comply with relevant COS and REACH regulations for export to Europe and other strict markets.
What is the typical lead time for bulk orders?
With an annual production capacity of 25,000 metric tons and a modern intelligent factory, we maintain strong inventory levels and efficient production schedules. Standard lead times are competitive, and we can provide specific timelines based on order volume and customization requirements upon request.
