Ethylene vinyl acetate (EVA) is one of the most widely used polymers from the group of acetates. Today, Asian countries are the largest consumers of EVA (ethylene vinyl acetate) in the world. Therefore, the demand for this widely used material is increasing day by day and many industries use it in making their products. From footwear and clothing industries to medical industries, EVA is used, which has many applications in different industries due to its properties and characteristics such as reasonable price, low weight, Odorless and high transparency compared to natural rubber. Among the industries that use EVA in the manufacture of their products, we can mention the footwear and the clothing industry, the sports equipment industry, the packaging industry, the electrical industry, the medical industry, etc. In this article, we tried to address the application of EVA in industries and examine this issue in detail. For more information about the application of EVA granules in industries and also to review the application of EVA compounds in industries, follow us further.
Appearance characteristics and chemical formula of EVA granule
Ethylene-vinyl acetate is a copolymer of ethylene and vinyl acetate. The weight percent of vinyl acetate usually ranges from 10 to 50 percent, with the rest being ethylene. EVA has an appearance, white powder, and odorless. EVA granules are in the form of balls or beads. which is usually transparent and has a shiny appearance, depending on the application of EVA in industries, it can be made into any desired appearance under appropriate heat.
It has a density of 0.926 to 0.950 and has a neutral Ph. The particle size of ethylene vinyl acetate is 90 micrometers and has a melting point of about 96 degrees Celsius. Its tensile strength is between 0.5% and 2% and its expansion coefficient is between 160 and 200. Also, the maximum temperature of its continuous use is 55 to 65. The chemical formula of EVA is as follows:
(C2H4)n(C4H6O2)m
This chemical formula indicates that in the structure of this type of copolymer, depending on the weight percentage of vinyl acetate, there are m units of vinyl acetate and n units of ethylene, in that order. Ethylene itself has a molecular formula of C2H4, and the chemical formula of vinyl acetate is C4H6O2. By combining these two, EVA is produced.

Application of EVA in industry
As you know, EVA is used in many industries due to its properties such as high flexibility, high resistance, excellent transparency, resistance to ultraviolet rays, dust and water, and biocompatibility. According to the application of EVA in industries, these properties can be different. Among the applications of EVA in industries, the following industries can be mentioned:
- Footwear and Clothing Industries: One of the applications of EVA compound in industries includes the footwear and clothing industries. EVA compound (Ethylene Vinyl Acetate) is a polymer with unique properties widely used in the footwear and clothing industries. These properties include flexibility, impact resistance, lightweight, color variety, resistance to abrasion and slippage, and ease of producing soles for sports shoes, walking shoes, and other shoes that require adhesion and stability, as well as sportswear and swimwear. This material is considered an ideal option for this industry.
- Hose Production Industry: EVA compounds are used in the production of various hoses, such as water hoses, air hoses, hoses for chemical transfer, medical hoses, and fuel hoses, due to properties such as flexibility, high durability, and resistance to sunlight and abrasion. To select the appropriate type of EVA compound for hose production, factors such as the intended use and environmental conditions should also be considered.
- Packaging industry: The use of EVA in the packaging industry is due to its flexibility, resistance to weather conditions, resistance to sunlight, prevention of water and dust penetration into the packaging, and its non-toxicity. It is used in packaging films, packaging sheets (such as aluminum sheets), packaging foams, bags, boxes, etc.
- Medical industry: One of the most important applications of EVA granules in industries is the medical industry. Due to properties such as compatibility with the human body, the ability to be sterilized, the ability to recycle, resistance and flexibility in this industry in the manufacture of medical equipment such as blood bags, breathing masks, serum and syringes, prostheses, wound dressings, sterile bags, Medical implants, sanitary appliances, braces, etc. are used.
- Electrical industry: The electrical industry is one of the most widely used applications of EVA in industries. This industry, due to its features such as excellent insulation, flexibility, resistance to wear, tear and chemicals, the ability to recycle this valuable material in its products in the production of insulated wires and cables, cable covers, insulated parts, fuse boxes, pipes It uses electricity, batteries, lamps and electronic components.
- Automotive industry: The application of EVA granules in industries, especially the automotive industry, is very abundant due to its unique properties. Among its most important properties, we can mention its flexibility, comfort, sound insulation and resistance to impact and chemicals, which protects car parts from physical and chemical damage. EVA was used in the production of products such as dashboards, steering wheel covers, seats, interior decorations, flooring, door gaskets, oil and air filters, etc.
- Sports equipment industry: EVA compound is known as a suitable and ideal material in the sports equipment industry due to its excellent properties. The application of EVA in industries, including the sports equipment industry, is due to its properties such as shock resistance, flexibility, lightness and comfort, resistance to wear and tear, and recycling. This material is used in the production of sports shoes, sports mats, sports clothes, sports bags, sports balls and sports equipment.
- Adhesive production industry: EVA is known as the main base of thermal adhesives due to its melting at low temperature and high adhesion. These adhesives are used in various industries such as packaging, carpentry, and furniture production. Among other applications, we can mention the production of organic adhesives, tape adhesives and liquid adhesives.
- Toy industry: The application of EVA in industries, including the toy industry, is due to its non-toxicity, flexibility, Washable, variety of colors, light weight and recyclability. This material is used in the production of foam toys, puzzles, dolls, control toys, intellectual games, etc.
