The product Ethylene Vinyl Acetate (EVA for short) is also known on the market as Poly (ethylene vinyl acetate) (PEV for short). PEV is a copolymer that mainly consists of two components: ethylene + vinyl acetate.
The composition of the product varies in the size component: 1. Vinyl acetate from 10 to 40%, 2. From 60% to 90% ethylene, without impurities and additives. In total, there are 3 brands of EVA product on the market, the difference of which is the amount of vinyl acetate used in the composition.
Up to 4% VA in EVA
A variety of EVA copolymer, in which the VA content does not reach 4%, is polyethylene. This type of copolymer is processed mainly as a thermoplastic in production. This variant of the product has the properties of low density polyethylene, its features are obvious gloss, increased degree of softness and mobility. From the point of view of the environment and human impact - the material is considered non-toxic.
4 to 30% VA in EVA
Such a copolymer is referred to as thermoplastic. In fact, it is not vulcanized, while it has the characteristics of rubber, in particular in the upper range.
11% content
Raw materials containing 11% VA. This version of the product is taken in production in the form of a hot melt adhesive.
60% in composition
EVA with an increased content of 60 percent or more is ethylene-vinyl acetate rubber.
Appearance and features
The main products that are made from the copolymer are rubber-like materials with excellent softness and high flexibility. As a rule, the material has good transparency and reflection in the form of gloss. Also, the product has a low-temperature structure with increased viscosity.
When using raw materials for the manufacture of insoles, the insoles are resistant to cracking, perfectly repel water and are resistant to UV rays. Considered specific - the smell of vinegar. It can also be an analogue of products made of rubber, vinyl polymer (due to which it is used in electrical engineering).

Products and items made of ethylene vinyl acetate
Hot melt adhesives are well-known cores for glue guns;
Football boots with the addition of wax and resin.
Raw Material - Adhesive additive for plastic bottles, wrappers, etc.
Multi-colored kraft foam sheets used for children's foam stickers.
EVA has also found its way into biomedical engineering in drug transport. This type of polymer is cleaved in an organic solvent, for example, in the same dichloromethane.
EVA is a raw material variant, which is also called foam rubber (foam rubber). It is used as stuffing in inventory for various sports. For example, in ski boots, saddles for exercise bikes and mountain bikes, in boxing gloves, in fishing equipment (handles for fishing rods and reels).
For example, shock absorbers for branded shoes such as Nike are made on its basis. It is used for cutting floats for gill-type gear.
It is used in the photovoltaic industry as a sealing material.
The same EVA slippers are extremely popular. After all, they are still weightless compared to classic sandals. Also, the final product is odorless, shiny and much cheaper than the same classic rubber option. In production, it is used as a cork in some devices.
Adhesives based on this substance are used in gluing packaging, as well as in the textile industry. For bonding plastic films, thin metal surfaces and as surface plastering powders.
Foam made from EVA has gained popularity in anime cosplay and cosplay games. Suits made from this foam are light, flexible and easy to put on. And most importantly, they are easy to make.
In art, foam sheets are also used. For example, flower buds are made from thin sheets of different shades. Why are EVA foam sheets used? - you ask. The answer is simple - all thanks to their flexibility and elasticity. Petals are obtained in a natural form, as close as possible to the original.
EVA is also used in the composition of paints with an increased water-thinning effect. Such paints are used mostly for interior work. The percentage of the main substance - dispersant, not less than 53%.

Tests and observations in the field of security / nature protection
Polyethylene vinyl acetate is a popular analogue of polyvinyl chloride, since this raw material does not contain chlorine. When compared with the data for the same 2014. such companies in the field of laboratory research as NTP, ACGIH and IARC did not reveal the harmfulness and carcinogenicity of the EVA polymer in nature. There were also no cases or claims of adverse effects on the health of adults or adolescents. The only disadvantage of this type of plastic is its long-term decomposition, as a result of pollution of nature during improper disposal by humans.

The thermal effect of EVA shoes, what is the secret?
Let's turn to physics ... Some materials are excellent heat conductors. For example, metal, water. Others are bad: the same plastic, synthetics, wood. For this reason, a boiled kettle should not be touched by hands, and plastic handles are provided on the same pots. All in order not to burn the skin.
Is the EVA ethylene vinyl acetate sole slippery or not?
The sole of this product, as well as other soles of the same rubber, are options for
Another example, an iron or marble bench is an order of magnitude cooler than a wooden one.
It practically does not conduct heat, so boots made from this material are used by hunters and fishermen. You can stand in the water and fish, while your feet will be warm and comfortable. And if there are also warm liners inside, then the normal temperature of the legs is ensured.
What is the secret of the lightness of shoes made of EVA?
The point is porosity, due to which any material options are light, almost airy. And the thing is that the copolymer is a very porous material. If we consider air, then it is an excellent heat insulator. Another reason is the retention of heat in cold conditions.
Lightweight EVA shoes: children's boots are almost weightless - about 220-350 grams. And adult models of boots - about 780 - 1000 grams per pair. When compared with classic rubber boots, they are 2-3 lighter.
It would seem - insignificantly 1 kg or 2 kg, but when you have to walk from 2 to 3 kilometers on uneven ground - such nuances matter.
How bad is EVA?
Absolutely harmless, while environmentally friendly. Not allergic, it is for this reason that so many children's toys and shoes are made from it.
EVA shoes - advantages:
- gives protection to the feet, calves in the cold season,
- reduces perspiration by helping the skin to breathe,
- airtight, so it does not allow the feet to get wet in any extreme situation,
- has high wear resistance, as well as excellent shock absorption,
- resistant to chemicals, which abundantly “fertilize” roads with salt, oil, gasoline,
- hypoallergenic.
