EVA ethylene vinyl acetate

Ethylene vinyl acetate is a very widely used thermoplastic polymer known by the abbreviation EVA. As its name suggests, this substance is composed of ethylene and vinyl acetate.

These products are so widely used that almost most industries depend on ethylene vinyl acetate and their absence can cause many problems. When this product is added to the materials, it gives a lot of flexibility and softness to the product and makes the obtained polymer maintain its hardness even at low temperature.

One of the main uses of this material is in the rubber industry. The tires obtained from this elastomer have high flexibility and are very resistant to sunlight and different weather conditions; Also, the produced rubber has good transparency and gloss.

The soles of most soccer shoes are made of ethylene vinyl acetate, with additives such as resin added to increase the adhesion of this polymer. When this elastomer is used in shoe soles, it is known as EVA, which is one of the most demanded types of soles after PVC and PU soles, which is often used in walking and sports shoes.

Because this material has a special softness, when a person runs with it, the sole of the shoe takes the shape of the foot and does not harm the foot. This material is not only used in the shoe and rubber industry, and industries such as the production of laminate flooring also use this material.

In addition to that, this material is used as a strong waterproof in automotive, adhesive and medical industries. The excellent adhesion of this good sealing product has made it used in the production of thermal adhesives.

On the other hand, it is also used in the packaging of goods, and industries such as paint and coating, agriculture and electrical industry, toys and wire pipes and cables all use this widely used thermoplastic.

Based on the type of use, this polymer is divided into three categories, which can be mentioned as EVA with low density, medium density and high density. This material is sold in different grades, of which the 18% grade is one of the most famous and widely used types in industries; Also, eva v430 grade is often used in the soles of shoes because of its very good thermal insulation; For this reason, most manufacturers of sports shoes have a demand to buy this material.

In fact, the benefits of using ethylene vinyl acetate in the industries mentioned above are that the following can be mentioned among the features of this substance:

• Their high impact resistance
• Very good optical properties
• Excellent transparency
• Fast and strong adhesion

Currently, the main producers of ethylene glycol acetate are European countries and South Korea. The use of this type of polymer is increasing day by day because it has a good price and the benefits of using it in the industry are very high.
