AS-8613: High-Molecular-Weight Anti-Tear Elastomer
Achieves a tear strength exceeding 23 N/cm without compromising resilience or compression performance. Say goodbye to trade-offs between resilience, shrink resistance, and tear resistance.
🚀 Key Advantages
- Performance Upgrade: Exceptional resilience, superior tear resistance, and excellent shape retention.
- Process Compatibility: Directly applicable to existing chemical foaming processes (no adjustments required).
- Uniform Plasticization: Rice-grain shaped granules enable better and more uniform processing compared to coarse materials.

Applications & Mechanism
Ideal for EVA Foamed Soles, Primary/Secondary Foaming, Midsoles, and IP Outsoles. In typical formulas (e.g., 10kg per 75kg raw materials), AS-8613 serves as a complete alternative solution with superior performance.
🛠️ Performance Optimization
AS-8613 acts as an interfacial tension agent for the EVA matrix, forming chemical bonds that prevent separation. Its flexible segments absorb tear energy and inhibit crack propagation, transforming material failure from brittle to ductile tearing. Tear strength typically increases by 60%–80%.

Frequently Asked Questions
What makes AS-8613 different from standard anti-tear additives?
Unlike standard additives that may compromise resilience or compression, AS-8613 uses a high-molecular-weight design that enhances tear strength (exceeding 23 N/cm) while simultaneously improving rebound rates and reducing shrinkage.
Can AS-8613 be integrated into existing production lines?
Yes. AS-8613 is fully compatible with existing chemical foaming processes and can be used as a direct alternative solution without requiring major adjustments to your current production setup.
What are the main benefits of the "rice-grain" shape?
The finer rice-grain shape provides more uniform plasticization during processing compared to larger blocks or coarse granules, ensuring a more consistent finished product.
By how much does it improve tear resistance in EVA soles?
Depending on the specific formulation ratios, tear strength typically increases by 60% to 80% due to the material's ability to absorb tear energy and inhibit crack propagation.
Is this material suitable for cold-weather applications?
Yes. As shown in technical data, it maintains a high resilience rate of 65-70% even at -30℃, outperforming many standard competitive materials.
How does AS-8613 affect the abrasion resistance of the sole?
By increasing the rebound rate and balancing thermal shrinkage, it enhances the overall durability and abrasion resistance (wear volume ≤0.3cm³/1.61km) of the final sole product.
