EVA and VAE are very different from eachother, but shares some properties as well.

What is VAE

VAE is a copolymer of Ethylene and VAM. Typically produced as dispersion with 55% solids in Water. VAE can be dried to powder form (DPP). This powder is water solluble and thermoplastic

What is EVA

EVA is produced as a solid plastic, also from VAM & Ethylene, but in a totally different process.

Where is VAE used?

VAE is used as binder or adhesive in wallpaints, textiles, adhesives and carpets. The dried form is typically used for cunstruction applications in concrete and tile applications. Special DPP-VAE is also used as Compatibilizers, impact improvers or adhesion promotors for bioplastics such as PLA and starch.

VAE has a lot of other applications, that can be found on this website.

Where is EVA used?

EVA (ethylene vinyl acetate) polymers are used in a wide variety of applications due to their unique combination of properties. Some common applications of EVA polymers include:

  1. Footwear: EVA is commonly used in the production of footwear components such as midsoles and outsoles due to its cushioning, shock absorption, and durability.
  2. Packaging: EVA is used in the production of packaging materials such as films, bags, and containers due to its clarity, flexibility, and low-temperature sealing properties.
  3. Adhesives: EVA is used as a binder in the production of hot melt adhesives, pressure-sensitive adhesives, and sealants due to its excellent adhesion to a wide variety of substrates.
  4. Foam: EVA foam is used in a wide range of applications, including sports equipment, toys, and protective padding due to its cushioning, shock absorption, and durability.
  5. Wire and cable: EVA is used as an insulating material in wire and cable applications due to its flexibility, toughness, and resistance to chemicals and environmental factors.
  6. Agriculture: EVA is used in agricultural applications such as greenhouse films and crop protection nets due to its excellent UV resistance and durability.
  7. Textiles: EVA can be used in textile applications as a coating or additive to improve water resistance, durability, and flexibility.

Overall, EVA polymers are used in a wide range of applications due to their unique combination of properties, including flexibility, toughness, excellent adhesion, cushioning, and shock absorption.

Why should I use the one (EVA) or the other (VAE)?

Most applications have a typical preference. Typical applications where DPP-VAE can be considered is to make water soluble versions of EVA (hot melts). E.g. for reactivation or recycling purposes.
