Updated: Apr 26, 2019

Let’s begin with one of the questions that is asked most often and made to be much more over complicated than is Vital.

What exactly is EVA sheet for footwear?

EVA Sheets for footwear are made from EVA or Ethylene vinyl acetate which is an extremely elastic material. EVA is an eco-friendly material and can be recycled. It is somewhat similar to rubber but has better toughness. This permeable plastic material has some unique properties like it is flexible, waterproof, stress crack resistant, low-temperature toughness and defiance from UV (ultraviolet) radiations. The odor of EVA is like vinegar, and in many electrical applications, it is competitive with rubber and vinyl polymer products.

EVA is made by combining two plastics, namely, vinyl acetate and ethylene. The rigidity of product plastic (EVA) depends on the above two plastics. The more the amount of vinyl acetate in the mixture, the less brittle the product. Below are the three formulations:


1.) Low Percentage Vinyl Acetate

When the percentage of vinyl acetate is low (usually up to 4%), in combination with ethylene, the formulation is the most brittle ones. This combination makes a hard foam product.


2.) Medium Percentage Vinyl Acetate

In combination with ethylene, when the percentage of vinyl acetate is medium (between 4% to 30%), the formulation, in comparison to the low percentage, is flexible.


3.) High Percentage Vinyl Acetate

If you want the most flexible and versatile formulation then the ratio of vinyl acetate in combination to ethylene should be greater than 40%.

Expanded Rubber or Foam Rubber are the two other popular names for EVA. The Foam Rubber or EVA is used in various sports accessories and equipment including bicycle saddles, hockey pads, martial arts & hockey gloves etc. With additional properties of man-made and animal-friendly material.

Applications of EVA SHEETS FOR FOOTWEAR

EVA is used in making vegan shoes. It has a major use in the Athletic Footwear Industry. It is used as a mid sole in the shoes or casual sandals. In recent years, PU tried to replace EVA Foam Sheets for the footwear mid sole, but it is said that EVA as compared to PU is more durable. Most of the running and casual footwear is made using these foam sheets as it provides better cushioning & protection to the feet.

Besides the addition to the Athletic Industry, there are several other applications of EVA. It is a material that is used to provide grip to just anything that needs them. Have you seen those flexible tubes of vacuum cleaners, beer brewing and industrial machines? Yes, they are made up of EVA only. Costumes for the high-budget films to add special effects and your fancy dress, all are made using this. It is a substitute material for the cork too.


THE SOLE – A FUNDAMENTAL PART FOR YOUR FOOTWEAR

EVA sheets are also used for the middle sole of shoe parts, out-sole & insole. There are the 3 Components of Soles :-


Out-sole – The bottom of the shoe.


Upper-sole – The fabric or leather part of the shoe that secures it to the foot.  The upper is either sewn or glued to the mid-sole.


Mid-sole-  The mid-sole is between the upper and the out-sole. The sole is that piece of the shoe that gives padding and bounce back, it shields the foot from feeling hard or sharp articles. If it is well made, it will pursue the foot line.

Soles made with EVA sheets provides extraordinary preferences for your feet. It gives strength against your foot, and in a specific order it is made to persevere your foot through all difficulties – the territory, an individual's weight, and every single conceivable weight that occur amid strolling or running.


A GUIDE TO CHOOSE THE BEST EVA SHEETS FOR YOU

As almost every industry uses this material for the production purpose, it is necessary to use the ideal ones. But how to pick up the best foam for you (depending upon the usage)? EVA foam comes up in three different categories; tile packs, roll mats and craft foam. They all differ in terms of size, thickness and price. The tile packs and roll mats come with two finishes, one side smooth and the other side patterned.

1.) Tile Pack

EVA Foam usually comes in Tile Pack. The size of a tile is usually 2ft x 2ft and have a thickness of 375 inches.

2.) Roll Mats

These mats of foam come in a roll, have the dimensions of 2ft x 6ft and have a thickness of 25 inches.

3.) Craft Foam

They come in different dimensions and vary. These are usually used for the art and craft purpose amongst the students.

4.)  Anti-vibrant

It should have good tensile strength & shock cushioning with high toughness

5.) Water and corrosion resistant.

In case of a soft or wet ground where the cleats dig underneath, it always provides a better grip.

So, depending upon the purpose, usage, thickness and price, you can easily choose the EVA Foam or sheet. While buying, if you are keeping the softness, elasticity and brittleness in mind then it is necessary for you to check the percentage of the Vinyl Acetate in combination with Ethylene. The lower the percentage of vinyl acetate more the brittleness. The higher the percentage more the flexibility. WHY TO CHOOSE POLYTAG INDIA FOR EVA SHEETS?
