Product Description

Why do most anti-tear materials fail?

Some materials incorporate tear-resistant additives that enhance resilience yet fail to meet tear resistance requirements or compromise compression performance. AS-8613 achieves true innovation by delivering a tear strength exceeding 23 N/cm without compromising other properties.

Core Promise: Say goodbye to trade-offs between resilience, shrink resistance, and tear resistance.
Performance Upgrade: Exceptional resilience, superior tear resistance, and excellent shape retention.
Process Compatibility: Directly applicable to existing chemical foaming processes with no adjustments required.
Uniform Plasticization: The rice-grain shape enables better and more uniform processing compared to coarse granules.

High-Molecular-Weight Anti-Tear Elastomer

Suitable for:

EVA Foamed Soles & Primary Foaming
Midsoles and Outsoles
EVA Secondary Foaming (IP Midsoles)

AS-8613 is a complete alternative solution. On the same dosage basis, it offers superior overall performance compared to standard supplements.

Application & Mechanism

As the interfacial tension agent for the EVA matrix, AS-8613 forms chemical bonds through group reactions, resolving separation issues. This constructs a synergistic network of "elastomer toughening + hard segment reinforcement."

Tear strength typically increases by 60%–80%. It also enhances sole rebound rate (≥55%) and increases abrasion resistance (wear volume ≤0.3cm³/1.61km).

Frequently Asked Questions

What is the primary innovation of AS-8613?

AS-8613 achieves a tear strength exceeding 23 N/cm (often increasing by 60%-80%) without compromising resilience or shrink resistance, unlike standard additives.

Is this material compatible with existing EVA production lines?

Yes, it is directly applicable to existing chemical foaming processes for EVA soles, midsoles, and outsoles with no adjustments required.

How does the rice-grain shape benefit the manufacturing process?

The fine rice-grain shape enables better and more uniform plasticization during processing compared to bulkier block or coarse granule formats.

How does AS-8613 perform in cold environments?

It maintains exceptional performance with a resilience rate of 65-70% even at extreme temperatures as low as -30℃.

What is the mechanism for improving tear resistance?

It acts as an interfacial tension agent, forming chemical bonds with EVA. Its flexible segments absorb tear energy and inhibit crack propagation, while rigid segments enhance bonding.

Can AS-8613 help reduce overall production costs?

Yes, high-concentration formulas offer superior dilution ratios and the material's multifunctional nature replaces the need for multiple separate additives.
