For any chemist, engineer, or procurement specialist involved in the chemical industry, a thorough understanding of a material's properties is essential for its effective and safe utilization. Ethyl Methacrylate (EMA), a fundamental monomer with the chemical formula C6H10O2 and CAS number 97-63-2, possesses a unique set of physical and chemical characteristics that dictate its wide range of industrial applications. NINGBO INNO PHARMCHEM CO.,LTD., as a key manufacturer and supplier, provides crucial insights into these properties.

Physically, Ethyl Methacrylate is characterized as a clear, colorless liquid. This visual clarity is often indicative of its high purity, a critical factor for polymerization processes. It possesses a distinct ester-like odor, which is typical for methacrylate monomers. With a density of approximately 0.91 g/cm³ at 20°C, it is less dense than water. Its boiling point is around 117-119°C, and it has a relatively low melting point of -75°C, ensuring it remains a liquid under most standard industrial storage and handling conditions.

Chemically, the most significant property of EMA is its reactivity, stemming from the presence of the vinyl group (C=C) within its methacrylate structure. This double bond readily undergoes free-radical polymerization, either on its own to form polyethyl methacrylate (PEMA) or copolymerized with other monomers. This inherent polymerizability is what makes EMA a valuable building block for creating a vast array of polymers and resins used in coatings, adhesives, plastics, and more.

The solubility profile of Ethyl Methacrylate is also noteworthy. While it is only slightly soluble in water (approximately 5.1 g/L at 20°C), it is highly miscible with common organic solvents such as alcohols and ethers. This characteristic is important for formulating solutions and dispersions used in various industrial processes, particularly in the manufacturing of coatings and inks.

Safety considerations are paramount when handling any chemical. EMA is classified as a flammable liquid, with a flash point typically around 20°C (68°F). This necessitates careful handling, storage away from ignition sources, and the use of appropriate personal protective equipment (PPE) like gloves and eye protection to prevent skin and eye irritation. While acute toxicity is moderate, prolonged or repeated exposure can lead to sensitization. Manufacturers and users must adhere to safety data sheets (SDS) provided by suppliers like NINGBO INNO PHARMCHEM CO.,LTD. to ensure safe handling, storage, and transportation practices.
