Technical Informations

Application Advice/Typical Applications

Ethyl acrylate is used primarily for manufacturing homopolymers and copolymers. Ethyl acrylate can be copolymerized for instance with acrylic acid and its salts, esters and acrylamide, with methacrylic acid, methacrylates, acrylonitrile, styrene, maleic acid esters, vinyl acetate, vinyl chloride, butadiene, unsaturated polyesters etc. Ethyl acrylate is an important raw material and a starting material for many chemical syntheses.

Shipping and Storage

Ethyl acrylate is transported in specially equipped railway cars or tanker trucks.
Transport containers are filled to a maximum of 92 % of their capacity.

In order to prevent spontaneous polymerization, ethyl acrylate must always be stored in under air, never under inert gases.  The air (oxygen) presence is required for a proper functionality of the stabilizer. Product storage temperature must not exceed 35°C. Under these conditions, a storage stability of one year can be expected. It is advisable to minimize the likelihood of ethyl acrylate overstorage by a strict observance of the “first-in-first-out” storage principle. For storage periods extended over one month, it is advisable to replenish the dissolved oxygen content in the product by suitable aeration.

Stainless steel or aluminium is the recommended material for storage tanks and piping. Even though ethyl acrylate does not corrode carbon steel, there is a risk of product contamination if corrosion occurs. All metal made equipment (tanks, pumps, piping etc.) must be earthed.

All national laws and directives, as well as local regulations governing storage, handling, distribution and disposal of flammable liquids must be strictly observed.

Avoid exposure to high temperatures, sparks, flame, light and frost. Keep separated from oxidizing materials. Keep the container tightly closed. For additional detailed information see the brochure „SAFE HANDLING AND STORAGE OF ACRYLIC ESTERS“, issued by the European Basic Acrylic Monomers Manufacturers Association (EBAM).
