Performance Advantages of EVA Taisox 7470M

  • High Flexibility and Elasticity. The 26% vinyl acetate content reduces crystallinity, providing softness, high elongation, and excellent rebound.
  • Excellent Foamability. Taisox 7470M is suitable for chemical or physical foaming processes, ideal for closed-cell foam products.
  • Durable and Weather Resistant. It shows strong resistance to water, oils, acids, and alkalis, with low water absorption and long-lasting outdoor performance.
  • Wide Processability. The material works well in injection molding, extrusion, and compression molding, offering a stable melt and wide processing window.
  • Regulatory Compliance. EVA 7470m meets FDA 21 CFR 177.1350 for food contact applications and complies with RoHS and REACH standards.

Typical Applications

  • Footwear Components. Insoles, midsoles, outsoles, and cushioning layers.
  • Foam Sheets and Pads. Shock-absorbing mats, vibration damping pads, sports, and construction materials.
  • Protective Packaging and Cushioning. Impact-resistant components and vibration-absorbing materials.
  • Blends and Masterbatches. Compatible with other polymers for color masterbatches, extrusion profiles, and tubing.
  • Flexible Injection-Molded Parts. Soft and resilient molded components for consumer or industrial use.
