Chemical Knowledge About Ethylene Vinyl Acetate 

What Is Ethylene Vinyl Acetate

Ethylene-vinyl acetate (EVA) is a general-purpose polymer with the molecular formula (C2H4)x.(C4H6O2)y, which is flammable and has no irritating odor. Water resistance: closed cell structure, non-absorbent, moisture-proof, good water resistance; Corrosion resistance, acid resistance, alkali resistance, alkali resistance, grease and other corrosion resistance, antibacterial, non-toxic, taste and pollution-free; Processability: no joints, it is easier to process such as hot pressing, cutting, gluing, laminating, etc.

Examples of Ethylene Vinyl Acetate

Ethylene

Its chemical formula is C2H4, the molecular weight is 28.06. Ethylene is one of the largest chemical products in the world, and the ethylene industry is the core of the petrochemical industry. Ethylene products account for more than 75% of petrochemical products and occupy an important position in the national economy.

Vinyl Acetate Polymer

Acetic anhydride also has various uses in manufacturing vinyl acetate polymer. The acid converts vinyl acetate monomer into polyvinyl acetate, a widely used compound used for making paints and lacquers. This process involves combining the anhydride with ethanol, which forms ethyl ethanoate by-product. Acid catalysts are then added to continue the reaction and produce the final product.

Vinyl Acetate Monomer

Acetic anhydride also has a variety of uses in manufacturing various products and materials, apart from the ones already mentioned above. It can be used as a solvent to dissolve other compounds or break down an existing compound into simpler forms. For instance, it can be used to make vinyl acetate monomer, which is a compound that is used extensively in the manufacture of acrylic fibers and certain types of plastic. Acetone is also produced as a by-product in this process.

Ethyl Acetate

It is used as a solvent and produces varnish, lacquer, and other coatings

Ethyl acetate is a common solvent used in many industries. It is soluble in water, but it can also be dissolved in other solvents. The solubility of ethyl acetate in water is affected by several factors, such as temperature and pH.

Ethyl acetate is soluble in water to varying degrees, with a solubility of about 8% at 25 degrees Celsius. The solubility of ethyl acetate in water is strongly dependent on the concentration of the solvent. Ethanol is entirely soluble in water at low concentrations, while ethyl acetate is only partially soluble at high concentrations.

Recent Market News

Shandong Is The Main Production Area

Shandong is the main production area of white latex, such as Jinan, Linyi, Dezhou, Yantai and Qingdao are the major demand areas for vinyl ACETATE. The annual consumption for vinyl acetate in Shandong was 65kt, excluding consumption of ethylene-vinyl acetate copolymer (EVA) units in Levima Group, which took up around 9.77% of the total circulation volume (including the consumption of EVA units in Levima Group here). The vinyl acetate is used to produce polyvinyl acetate and other products.  

Product Prices Are Soaring, Rising Again And Again

In the context of the rapid growth of the photovoltaic industry, the market demand for EVA (ethylene-vinyl acetate copolymer) resin, especially high-end photovoltaic materials, is strong. In addition, the port congestion caused by the epidemic has hindered the import of EVA. Since the beginning of this year, the supply and demand pattern of the EVA market has been tight. Product prices are soaring, rising again and again.

New Project Is Being Built

The construction of the project includes a million-ton-level ethylene plant, as well as a 10/700,000-ton/year ethylene oxide/ethylene glycol device, a 600,000-ton/year styrene device, a 350,000-ton/year polypropylene device, and a 300,000-ton/year 9 sets of chemical plants and supporting utilities including an ethylene-vinyl acetate resin plant, a 100,000-ton/year thermoplastic elastomer plant, etc., with a total investment of 27.8 billion yuan, and an estimated annual output value of 26 billion yuan, which can stimulate the local downstream industry of over 100 billion yuan.

International Market

On February 18, 2021, chemical producer Celanese Corp (Celanese Corp) stated that due to severe weather in Texas, it announced force majeure for deliveries in the Americas and Europe, the Middle East and Asia (EMEA). These include acetic acid, vinyl acetate monomer, ethyl acetate and ethylene-vinyl acetate copolymer.
