    Product Description

    Ethyl Acrylate (EA) CAS 140-88-5 is ethyl 2-propenoate, with EC 205-438-8 and molecular formula C5H8O2.

    Synonyms: Ethyl 2-propenoate; Acrylic acid ethyl ester; Ethyl propenoate.

    CAS: 140-88-5.

    Molecular formula: C5H8O2.

    It is supplied as a clear, colourless liquid.

    It is positioned as a stabilised acrylic ester monomer for copolymer manufacture and synthesis routes.

    It is used where ethyl acrylate is specified and is not Ethyl Acetate or a finished polymer formulation.

    It is used in acrylic copolymers for industrial coating and ink-binder resins.

    It is used in adhesive and sealant polymer systems with EA as a named comonomer.

    It is used in emulsion and solution polymer manufacture for resin-dispersion routes.

    It is used in chemical synthesis as an acrylic ester feedstock.

    Poly(ethyl acrylate) has a low glass transition temperature of about -24 C, making the polymer chain flexible at service temperature.

    Selecting EA in an acrylic copolymer helps reduce hardness and improve adhesion, elongation and low-temperature performance.

    It is normally inhibited with MEHQ, often at about 15 ppm, to prevent unintentional polymerisation.

    Confirm ethyl acrylate identity, monomer assay, inhibitor system, colour, water and acid-value limits.

    Store cool, away from heat and ignition sources, and confirm the inhibitor level before polymerisation or synthesis.

    Use suitable PPE when handling and follow the current SDS.

    FAQ - Technical & Supply Chain

    • Q:

      What is Ethyl Acrylate EA CAS 140-88-5?

      A: Ethyl Acrylate, commonly abbreviated EA, is an acrylic ester monomer with molecular formula C5H8O2. It is supplied as a stabilized liquid for copolymer manufacture and synthesis routes, not as a finished coating, adhesive or polymer dispersion.
    • Q:

      Is Ethyl Acrylate the same as Ethyl Acetate?

      A: No. Ethyl Acrylate is an acrylic monomer used to build polymers, while Ethyl Acetate is a saturated ester commonly used as a solvent. The two have different reactivity, applications and safety profiles and should not be interchanged.
    • Q:

      What are the main applications of Ethyl Acrylate?

      A: EA is used as a comonomer in acrylic copolymers for coatings, inks, binders and pressure-sensitive adhesives. It also appears in emulsion and solution polymer routes for textile, leather, paper and sealant systems where softness and flexibility are needed.
    • Q:

      Why does Ethyl Acrylate improve polymer flexibility?

      A: Poly(ethyl acrylate) has a low glass transition temperature of about -24 deg C, which makes the polymer chain flexible at service temperature. Selecting EA in an acrylic copolymer helps reduce hardness and improve adhesion, elongation and low-temperature performance.
    • Q:

      How should Ethyl Acrylate be stored and inhibited?

      A: Ethyl Acrylate can polymerise unintentionally, so it is normally inhibited with MEHQ, often at about 15 ppm. Store it cool, away from heat and ignition sources, and confirm the inhibitor level before polymerisation or synthesis because its level affects induction time and process control.
