Ethyl Acrylate (EA Monomer) Supplier in Malaysia
- Also known as
- Ethyl Acrylate Monomer
- Acrylic Acid Ethyl Ester
- Ethyl Prop-2-Enoate
- Ethyl 2-Propenoate
Ethyl acrylate supplier in Malaysia for the emulsion polymer, binder and adhesive trade, covering the monomer itself rather than a finished latex. Specification sheets write it as ethyl acrylate monomer or acrylic acid ethyl ester, CAS 140-88-5, formula C5H8O2. Ethyl acetate is a different chemical despite the similar name, so quote the CAS number where an order could be misread.
Commercial lots are inhibited, normally with MEHQ, since an unstabilised acrylate will polymerise on its own. Offers then separate on inhibitor condition and on water, acidity and colour limits, while a few routes specifically want low-inhibitor or uninhibited material. No stabiliser figure appears on this page because it belongs with the documentation for the lot being quoted.
Formulators use the ethyl ester to balance hard and soft monomers in a copolymer, landing on a target film hardness while keeping the film flexible. That work runs through acrylic emulsion binders, textile finishing and pigment printing, nonwoven and carpet-backing latices, paper and leather coating binders, acrylic rubber, and flocculant or thickener copolymers. Its odour is sharper than most of the family and registers at very low concentration, which shapes how a plant transfers and vents it.
Send the polymer system, inhibitor requirement, specification limits, quantity and delivery location with your enquiry. Availability, pack format, documentation and timing are confirmed in the quotation. Supply is subject to applicable requirements.

Ethyl Acrylate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Inhibited technical ethyl acrylate | clear, colourless inhibited liquid | — | Standard polymer-grade monomer for emulsion and solution copolymerisation, carrying the MEHQ stabiliser that ordinary handling assumes. Latex binder, adhesive and coating resin plants running a settled recipe buy this row. | Drum, IBC and bulk parcels are all ordinary formats for this monomer; the pack is fixed in the quotation. |
| Ethyl acrylate at a stated inhibitor range | clear, colourless inhibited liquid | — | For buyers whose purchase specification names a stabiliser range, since that figure decides shelf life and how evenly initiation begins. Quote the range your process works to and it can be checked against what is offered. | Drum, IBC and bulk parcels are all ordinary formats for this monomer; the pack is fixed in the quotation. |
| Low-inhibitor or uninhibited ethyl acrylate | clear, colourless liquid monomer | — | Asked for where residual stabiliser holds back initiation or interferes with a grafting step. Lots of this kind are drawn down soon after arrival under close temperature control, so describe the timing you plan for. | Confirm the required pack format with the quotation. |
| Ethyl acrylate to tighter water, acidity and colour limits | clear, colourless inhibited liquid | — | Selected when moisture or free acid would disturb a sensitive initiator system, or when a textile or paper binder has to dry pale. Send the numbers your specification carries rather than leaving them implied. | Drum, IBC and bulk parcels are all ordinary formats for this monomer; the pack is fixed in the quotation. |

Ethyl Acrylate applications
Safety and handling
Ethyl acrylate is a polymerisable liquid monomer whose odour carries at very low concentration, so closed transfer and effective ventilation are the practical starting points. Store containers closed and cool, clear of heat, ignition sources, oxidising agents and peroxide initiators. Stabiliser systems rely on dissolved oxygen and are used up over time, so storage temperature, shelf life and inhibitor condition belong to the safety data issued with the grade received rather than to this page. Supply is subject to applicable requirements.
Common questions about ethyl acrylate
Is ethyl acrylate the same as ethyl acetate?
No, and the two names sit close enough together that orders occasionally cross. The acrylate is a reactive monomer that builds acrylic polymer chains, while the acetate is a solvent that leaves a formulation again without reacting. Quote CAS 140-88-5 whenever there is any doubt about which one is wanted.
What is the difference between ethyl acrylate and the other acrylate esters?
The alcohol group on the ester decides how soft the resulting polymer turns out. Methyl acrylate gives the hardest film, the ethyl ester is a step softer, and the butyl and 2-ethylhexyl esters are softer again, which is why those two are used as soft monomers. A recipe is built around one ester and is not swapped over without reformulating.
Why is ethyl acrylate stabilised with MEHQ?
Left alone the monomer starts to polymerise with warmth or simply with time, so trade material carries an inhibitor. MEHQ depends on a trace of dissolved oxygen to work and is gradually consumed, which is why both fully oxygen-free storage and warm conditions shorten the protection. Buyers who care about that write an inhibitor range into the purchase specification.
Can ethyl acrylate be supplied without an inhibitor?
Some polymerisation routes want low-inhibitor or uninhibited material because the stabiliser slows initiation or gets in the way of grafting. Material like that is consumed soon after it arrives and under temperature control, so set out the process and the timing you plan for when enquiring.
Why does ethyl acrylate smell so strong?
Its odour threshold is unusually low, so the vapour is noticeable well before there is any visible loss of product. Plants changing over from a heavier acrylate normally look at closed transfer, ventilation and vapour control first. Work from the safety data issued with the grade received.
What is needed for an ethyl acrylate price enquiry in Malaysia?
The specification you polymerise to, the inhibitor requirement, quantity, preferred pack format and delivery location. With those in hand the monomer can be quoted on enquiry with a stated validity period, which is how it is priced rather than from a published list.
