EVA (Ethylene Vinyl Acetate) - Flexible, Lightweight, and Versatile Polymer

EVA Product - Ethylene Vinyl Acetate

EVA (Ethylene Vinyl Acetate) is a thermoplastic copolymer known for its flexibility, light weight, and impact-absorbing properties. EVA retains its flexibility even at low temperatures, is resistant to chemicals, and is non-toxic. These features make it suitable for a wide range of applications.

Thanks to its soft structure, high elasticity, and excellent impact cushioning, EVA is widely used in foam and film form. It is easy to process and can be shaped using various molding techniques.

Technical Specifications

  • Density: 0.91 – 0.96 g/cm³ (lightweight structure)
  • Melting Point: 85 – 96°C (low melting temperature)
  • Flexibility: High (depends on vinyl acetate content)
  • Shore Hardness: 25 – 90 A (suitable for various applications)
  • Transparency: Good (in low VA content grades)

Applications

Due to its shock-absorbing, flexible, and lightweight nature, EVA is commonly used in the following areas:

  • Shoe soles and insoles (for comfort and flexibility)
  • Toys and children's products (safe and non-toxic structure)
  • Packaging and protective foams (lightweight and impact absorbing)
  • Adhesive films and coatings (low-temperature adhesion)
  • Sports equipment and mats
  • Construction and insulation products (sound and thermal insulation)
  • Solar panel encapsulants

Advantages

  • High flexibility and impact absorption
  • Resistant to chemicals and UV rays
  • Easy to process and manufacturable in various forms
  • Maintains flexibility even at low temperatures
  • Non-toxic and skin-friendly structure
  • Waterproof and weather-resistant

Additional Information

EVA is produced by the copolymerization of polyethylene and vinyl acetate monomers. As the vinyl acetate content increases, flexibility increases and crystallinity decreases. This ratio plays an important role in determining the product's application area.

Thanks to its eco-friendly and non-toxic nature, it is preferred in children's products and the medical field. Moreover, EVA foams are recyclable and can be used in sustainable production processes.
