Taisox 7350M is designed as a general-purpose EVA copolymer resin suitable for foaming, molding, and sheet extrusion applications. Manufactured through a high-pressure copolymerization process, vinyl acetate (VA) is incorporated into the ethylene polymer chain to provide a soft, elastic material with excellent flexibility and processing performance.

Recommended Applications

  • Foamed Materials: EVA-based foam components for cushioning and packaging.
  • Footwear Industry: Midsole, insole, and sheet materials for shoes.
  • Shock-Absorbing Components: Sports mats, protective packaging, and padding.
  • Sealing and Gasket Materials: Soft foams and flexible parts.

Main Features

  1. High Flexibility and Elasticity. With elongation at break up to ~800%, EVA 7350M provides excellent cushioning and impact resistance.
  2. Excellent Low-Temperature Toughness. This resin maintains flexibility even at very low temperatures.
  3. Chemical Resistance. Resistant to general acids, alkalis, and other chemicals.
  4. Crosslinkable. Taisox 7350M is suitable for peroxide or sulfur crosslinking foaming processes.

Compliance and Certifications

  • Food Contact Safety: Certain grades meet US FDA 21 CFR 177.1350 requirements for food contact.
  • RoHS Compliant: Meets European environmental safety standards (verification required per batch).
  • Safety Considerations: EVA copolymer is non-hazardous, though dust control is recommended during processing.
