1. Product Specifications & Comparative Analysis

2. Industrial Applications & Functional Mechanisms

This organozinc compound serves as an advanced accelerator in polymer engineering with dual functionality:

• Vulcanization Optimization: Reduces scorch time by 18-22% compared to conventional accelerators while maintaining optimal crosslink density (1.5-2.0×10^-4 mol/cm³)
• Environmental Compliance: Meets EU REACH Annex XVII restrictions on nitrosamine emissions (＜0.1 ppm)
• Composite Enhancement: Improves tensile strength (15-20% increase) and compression set resistance in EPDM formulations

3. Operational Protocols & Safety Considerations

Recommended Dosage: 0.8-1.5 phr in NR/SBR compounds
Compatibility Matrix:
– Optimal with Sulfur (1.2-2.0 phr)
– Compatible with ZnO (3-5 phr)
– Avoid combination with lead-based stabilizers

4. Industry Implementation Case Studies
