What is VAE dispersion?

VAE (Vinyl Acetate Ethylene) polymer is made by polymerizing Vinyl Acetate (VA) and Ethylene (E) monomers. This process typically involves the use of a free radical initiator and a reactor under controlled temperature and pressure conditions. The reaction results in the formation of a copolymer of VA and E, which has properties that are intermediate between those of polyvinyl acetate (PVA) and polyethylene (PE). VAE polymers are commonly used in applications such as adhesives, paints, and coatings.

Where are VAE dispersions used for?

the main Application Areas for VAE are:

  • Adhesives
  • In combination with bioplastics like PLA
  • Architectural coatings
  • In combination with biopolymers, like starch
  • Construction
  • Nonwovens
  • Carpets
  • Paper
  • Caulks and sealants

Why should one consider useing VAE polymer dispersions?

VAE have in general very good adhesion to a wide range of substrates, including wood, paper, metal, plastics and concrete

  • Broad range of available glass transition temperatures (Tg)
  • LOW VOC (in most cases, only Acetic acid is relevant)
  • The VAE formulation strategy eliminates the need to add plasticizers
  • Most products are water soluble
  • Good film-forming properties at low temperatures and without additional coalescing agents
  • VAE is thermoplastic, and solluble therefor offer good properties for recycling of plastics
    • It could be mechanical recycled being a minor part in e.g. with thermoplastic carpet waste streams as PET/ PE/PP
    • Seperation of assembled products is relatively easy, with alkaline water or mild solvents
  • Excellent filler acceptance
  • Excellent cohesion
  • Very high Compatibility with other binders and additives
  • Heat and fire resistance over a wide range
  • Potentially to be fully biobased. Currently available in the market as bio mass balanced versions.
  • All modern dispersions are produced without added APEOs
