Zinc Diacrylate (ZDA), as a specialized vulcanizing agent for golf ball cores, is engineered for high rebound resilience, impact resistance, and long service life:

1. Ultra-Fast Crosslinking

During high-temperature vulcanization (160–180°C), the crosslinking reaction completes within 10–15 seconds, significantly shortening the core production cycle and improving efficiency.

2. Energy Conversion Optimization

Through an ionic bond crosslinking network, the efficiency of converting impact kinetic energy into elastic potential energy is increased by 30%–50%, achieving greater flight distance (COR value ≥0.83).

3. Fatigue Resistance

After 100,000 impact tests, the core hardness retention rate remains >95%, with a rebound decay rate of <3%, far surpassing traditional peroxide vulcanization systems.

4. Environmental Compatibility

No volatile by-products are generated, complying with USGA/R&A environmental regulations for golf equipment, and is compatible with water-based polybutadiene rubber systems.

 Introduction to Zinc Diacrylate as a Vulcanizing Agent for Golf Ball Cores:

Dual/Triple-Layer Core: Serves as the primary crosslinking agent, providing gradient hardness to the core (inner layer: 50–60 Shore C, outer layer: 70–80 Shore C), balancing impact feel and flight stability.

High-Speed Spin Control: By regulating crosslinking density, it minimizes spin rate fluctuations (within ±50 rpm), enhancing control precision for professional players.

Zinc Diacrylate is also applicable in vibration-damping layers for tennis rackets and midsole foam materials for running shoes, improving energy return efficiency (energy loss rate reduced to 10%–15%).

 Storage:

Store away from light and moisture (below 25°C).
