What is Ethyl acrylate?
Ethyl acrylate (CAS 140-88-5), or EA, is a reactive acrylic monomer used as a building block in polymer synthesis and as a flavoring agent in food.
Where is Ethyl acrylate used?
- Coatings, adhesives and packaging: primary monomer in emulsion polymerization for acrylic coatings, pressure-sensitive adhesives and flexible packaging films requiring low glass transition temperature
- Printing and packaging: incorporated into water-based inks and overprint varnishes to improve substrate adhesion and film flexibility
- Textile and leather: EA-based copolymers for soft, durable surface coatings
- Flavoring: contributes pineapple and fruity notes at trace concentrations
- It copolymerizes with other acrylates and vinyl monomers to produce resins with controlled flexibility and adhesion.
Good to know: Stabilized with hydroquinone monomethyl ether to prevent premature polymerization during storage and transport. Food-grade material conforms to FEMA specifications; FEMA 2418.
Commercial specifications
- Purity commonly 99% or higher
