Primary Uses of LG EVA EA28025

  • Hot Melt Adhesives (HMA).
  • Foamed products, such as footwear components and cushioning materials.
  • Flexible films and sheets.
  • Laminated and coated materials.
  • General flexible plastic applications.
  • Wire and cable compounds.

Product Features

  1. Excellent Flexibility and Elasticity. The vinyl acetate content of approximately 28% significantly reduces crystallinity, resulting in superior softness, flexibility, and elastic recovery compared to conventional polyethylene materials.
  2. Good Adhesion Properties. EVA EA28025 exhibits strong adhesion to various substrates and is widely used as a base polymer in hot melt adhesive (HMA) formulations. It demonstrates good compatibility with tackifying resins, waxes, and other functional additives.
  3. High Melt Flow and Easy Processing. With a melt flow rate of approximately 25 g/10 min (190 °C / 2.16 kg), the resin provides excellent flow behavior, enabling smooth processing in extrusion, injection molding, coating, and hot melt applications.
  4. High Elongation and Impact Resistance. The material offers high elongation at break and good impact resistance, contributing to improved durability and resistance to cracking under mechanical stress.

Storage & Handling

To maintain product quality and performance, the following storage conditions are recommended:

  • Store in a cool, dry environment.
  • Recommended storage temperature: 10–25 °C.
  • Avoid prolonged exposure to heat above 35 °C.
  • Prevent excessive stacking pressure to avoid pellet deformation.
  • Apply a first-in, first-out (FIFO) inventory system.
