Snapelastomer For EVA Solving The Slip Vs Wear Trade-Off In EVA Foam Sole Systems

EVA foam remains one of the most widely used materials in modern footwear, especially for midsoles and lightweight sole systems.

However, EVA formulations have long faced a critical limitation:

. Improving abrasion resistance often reduces surface grip

. Enhancing slip resistance typically compromises durability

This“slip vs. wear” trade-off has been widely accepted as unavoidable in EVA systems.

But what if EVA no longer needs to compromise?

The EVA Challenge - Why Durability and Grip Conflict

EVA (Ethylene-Vinyl Acetate) is valued for its lightweight, flexibility, and cushioning properties.

Yet when it comes to performance:

Key Issues in EVA Sole Formulations

. Low surface friction → insufficient grip, especially in wet conditions

. Poor abrasion resistance → faster wear and shorter product life

. Traditional additive limitations:

. Silicone additives → improve wear but reduce traction

. Rubber blending → improves durability but affects foam structure and processing

→ Result: EVA compounds struggle to balance comfort, durability, and safety

Introducing Snapelastomer 2802 - A New Approach to EVA Performance Optimization

Snapelastomer 2802 is SILIKE's next-generation slip-resistant and wear-resistant elastomer additive, specifically engineered for EVA foaming systems.

It is designed to eliminate the long-standing trade-off between traction and abrasion resistance in footwear materials. Unlike conventional additives that typically improve one property at the expense of another, Snapelastomer 2802 enables simultaneous enhancement of surface friction and wear durability through a unique viscoelastic mechanism within the EVA matrix.

1) Dual Performance Enhancement: Slip Resistance + Wear Resistance

As a dual-function anti-slip and anti-abrasion additive, Snapelastomer 2802 significantly improves both traction performance and abrasion resistance in EVA soles, enabling safer and longer-lasting footwear.

2) Reduced DIN Abrasion, Extended Service Life

The incorporation of Snapelastomer 2802, a grip-enhancing and wear-resistant additive, effectively reduces DIN volume loss, resulting in improved wear durability and extended sole service life.

3) Breakthrough in Wet & Dry Grip Performance

Unlike conventional wear-resistant additives that tend to reduce the friction coefficient, Snapelastomer 2802 functions as a wear resistance modifier and traction-enhancing additive that increases both dry and wet friction coefficients through its viscoelastic mechanism, addressing the issue of slippery performance under wet conditions.

4) Excellent Dispersion in EVA Foaming Systems

With optimized interfacial compatibility, Snapelastomer 2802, a functional footwear additive, achieves uniform dispersion within EVA foaming systems, ensuring stable processing and consistent performance.

5) Preserves Mechanical Properties

At recommended dosage levels, grip enhancer and abrasion-resistant additive Snapelastomer 2802, delivers functional improvements without compromising key mechanical properties such as tensile strength, tear strength, and hardness.
