Taisox EVA 7350M

High-Performance EVA Copolymer for Cross-Linked Foam, Gaskets & Industrial Applications

Taisox EVA 7350M is the benchmark 18% vinyl acetate copolymer resin from Formosa Plastics (Taiwan), designed for high-performance, cross-linked foam and industrial applications. Manufactured using advanced high-pressure polymerization, this grade delivers exceptional crosslinkability, elasticity, and chemical resistance-making it the trusted choice for India’s leading footwear, gasket, cable, and technical compound manufacturers.

Product Overview & Manufacturing Excellence

Taisox EVA 7350M is a soft, flexible thermoplastic copolymer engineered for demanding environments. Its 18 wt% vinyl acetate content is optimized for cross-linking, delivering a unique combination of high elasticity (~800% elongation), mechanical strength, and chemical resistance. Manufactured by Formosa Plastics using proprietary high-pressure technology, every batch offers consistent melt flow, uniform molecular weight, and reliable mechanical properties. 

  • Base Polymer: Ethylene-Vinyl Acetate Copolymer (EVA) 
  • Vinyl Acetate Content: 18 wt% (optimized for cross-linking) 
  • Melt Index: 2.5 g/10 min (@190°C/2.16kg) 
  • Density: 0.938 g/cm³ 
  • Melting Point: 84°C 
  • Physical Form: Pellets/Granules (25 kg bags, natural/white)

 Why Taisox EVA 7350M Outperforms

  • Highly Crosslinkable: Engineered for peroxide cross-linking; achieves 70-90% gel content for permanent thermoset foam. Delivers <10% compression set at 70°C-ideal for premium footwear, gaskets, and seals. 
  • Exceptional Elasticity: ~800% elongation at break ensures maximum flexibility and comfort, even after cross-linking. 
  • Outstanding Chemical Resistance: Superior resistance to UV, ozone, oils, solvents, and environmental stress-cracking-suitable for outdoor and industrial use. 
  • Low Processing Temperature: 84°C melting point reduces energy costs, minimizes degradation, and allows faster production cycles. 
  • Superior Durability: Cross-linked foam lasts 3-4x longer than uncross-linked EVA, with 5+ year lifespans in demanding applications.

FAQs

Frequently Asked Questions

What makes Taisox EVA 7350M better than standard EVA grades?
Taisox 7350M is engineered for cross-linking, achieving 70-90% gel content for ultra-durable, thermoset foam. Outperforms standard EVA for premium shoes, gaskets, and long-life products.
Cross-linking converts EVA 7350M from a thermoplastic to a thermoset, giving <10% compression set, 3-4x longer life, and superior resistance to flattening, UV, and chemicals.
Process at 150-180°C for molding, extrusion, or foam expansion. Use 0.5-3% peroxide for cross-linking. Keep feed dry and avoid >190°C.
Taisox 7350M is optimized for cross-linking (best for premium, long-life foam). Sipchem 2518 Co is standard for uncross-linked foam. DuPont is premium but not cross-link optimized.
Blend with 1-2% dicumyl peroxide, mold at 150-180°C, post-cure at 80-120°C for 2-4 hours. Target 75-85% gel content for best balance of durability and processability.
Base resin meets FDA and RoHS for indirect food contact. For direct contact, commission third-party migration testing and certification.
Available pan-India: Delhi NCR: 1-2 days Mumbai: 1–2 days Gujarat: 2-3 days Haryana: 2-3 days MOQ: 1000 kg (sample), 5 MT+ (bulk); volume discounts apply.
