Product overview
Ethyl acrylate (ethyl prop-2-enoate, CAS 140-88-5) is the ethyl ester of acrylic acid. It is a colorless, highly mobile liquid with a penetrating, fruity odor and limited water solubility. With a homopolymer glass-transition temperature of about −24 °C it sits between methyl acrylate and butyl acrylate on the hardness scale, which makes it a useful monomer for tuning film flexibility and toughness.
The grade offered is specified at ≥ 99.0 wt% purity, ≤ 10 APHA color, ≤ 0.1 wt% moisture and a density of 0.9233 g/cm³ at 20 °C, stabilized with 100 ± 10 ppm MEHQ. The monomer melts at −71.2 °C and boils at 99.4 °C; its flash point of 9 °C means it is handled as a highly flammable liquid.
Ethyl acrylate is transported as UN 1917, packing group II. ChemPortal supplies it in plastic drums, IBC totes and ISO tank containers, with a certificate of analysis for every lot.

Frequently asked questions
Where is ethyl acrylate used instead of butyl acrylate?
Where a harder, more chemical-resistant film or a lower monomer boiling point is wanted, for example in acrylic elastomers, textile binders and emulsions that need good oil and solvent resistance.
What safety precautions apply?
Ethyl acrylate is highly flammable (flash point 9 °C) and has a strong odor; use grounded equipment, closed transfer systems and good ventilation. Keep the inhibitor active by storing with air in the headspace, below 35 °C and away from light.
What is the inhibitor and level?
The monomer contains 100 ± 10 ppm MEHQ (hydroquinone monomethyl ether). For most emulsion and solution polymerizations this level does not need to be removed.
In what packaging is it sold?
Plastic drums, 1,000 L IBC totes and ISO tank containers. Send the quantity and destination to receive a delivered wholesale quotation and the SDS/TDS.
