Snapelastomer 2802 - FAQ for EVA Sole Materials

Q1: Why is EVA slippery when wet?
A: EVA has relatively low surface friction, especially when water acts as a lubricant. Conventional additives often fail to maintain high friction under wet conditions, leading to slip hazards.

Q2: How does Snapelastomer 2802 improve EVA sole performance?
A: Snapelastomer 2802 significantly enhances both wear resistance and slip resistance in EVA soles, solving the common issue of "slip when wet" while improving the material’s durability.

Q3: Can Snapelastomer 2802 be used in EVA foaming systems?
A: Yes, Snapelastomer 2802 is specially designed for EVA foaming systems and does not interfere with the foam structure or processing performance. It disperses well and ensures stable foaming.

Q4: How does Snapelastomer 2802 compare to traditional wear-resistant additives?
A: Traditional wear-resistant additives often reduce friction, causing a trade-off between grip and durability. Snapelastomer 2802, however, uses a unique viscoelastic mechanism to improve both abrasion resistance and friction without compromising either.

Q5: Does Snapelastomer 2802 affect the mechanical properties of EVA?
A: No, Snapelastomer 2802 has minimal impact on key mechanical properties like tensile strength, tear strength, and hardness. It provides functional modification without sacrificing the base material's performance.

Q6: What is the typical application for Snapelastomer 2802 in footwear?
A: Snapelastomer 2802 is ideal for sports and casual shoe soles that require enhanced wear resistance and slip resistance, particularly in dynamic environments where both safety and durability are critical.

Q7: What performance benefits can be expected from Snapelastomer 2802 in EVA soles?
A: You can expect improved abrasion resistance, enhanced dry and wet traction (with a COF ≥ 0.45), reduced DIN volume abrasion loss, and stable processing characteristics in EVA footwear formulations.

Q8: Is Snapelastomer 2802 compatible with lightweight EVA formulations?
A: Yes, Snapelastomer 2802 works well with lightweight EVA systems, providing both grip and durability without adding excessive weight, making it ideal for athletic and casual footwear.

Q9: How does Snapelastomer 2802 improve the safety of EVA soles?
A: By enhancing both wear resistance and wet slip resistance, Snapelastomer 2802 significantly improves the safety and comfort of footwear, preventing slip accidents in both dry and wet conditions.
