Description

Product Description:
AS-6682E is a high-performance compound modifier featuring “polarity regulation – interfacial compatibilization – functional synergy.” It effectively solves key problems in TPEE, EVA, and nylon foam sole blending, including poor compatibility, mechanical imbalance, and unstable foaming.

Key Benefits:

🔹 Enhanced Compatibility for Uniform Foaming

• Forms hydrogen bonds with nylon (amide groups) and polar adsorption with TPEE (ester groups)
• Improves interface bridging among different polarity regions, preventing delamination
• Achieves uniform foam nucleation and pore density up to 650 pores/cm² with <5% large pores

🔹 Mechanical Strength Improvement

• Increases tensile strength by 15–25% (up to 15 MPa)
• Improves tear resistance by 20%, avoiding cracks at bends
• Enhances rebound rate (85–90%) and fatigue resistance (up to 80,000 cycles)

🔹 Optimized Foaming Process Stability

• Reduces melt viscosity and stabilizes foam expansion (1.8–3.5x)
• Ensures dimensional accuracy (±1%) and reduces water absorption by up to 20%
• Increases closed-cell rate from 60–70% to 80–90%

🔹 Surface & Environmental Resistance

• Reduces stickiness and friction coefficient by 10–15%
• Improves abrasion resistance (Taber wear loss drops from 0.08g to 0.05g/1000 rev)
• Maintains flexibility at -20°C and resists hydrolysis (retains 85% strength after 500h boiling)

Recommended Dosage:

• 2%–6% based on the total compound weight
  • TPEE-rich blends: 2%–4%
  • Nylon-rich blends: 4%–6%
  • Excess use may cause surface blooming or reduced rigidity

Applications:

Sports shoe soles, casual footwear, high-performance foamed sole systems requiring excellent compatibility, elasticity, durability, and environmental resistance
