Ethylene Vinyl Acetate Shoe Sole

The invention discloses a light weight eva ethylene vinyl acetate shoe sole material and a preparation method thereof.

Ethylene vinyl acetate shoe sole.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. The cushioning of ethylene vinyl acetate shoes was diminished after 500 km compared with that at 0 km 968 0 25 9 n vs. The material comprises the following components in parts by weight. Eva outsole is the lightest among all kinds of outsoles.

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. Eva is now the most widely used midsole material for shoes. Ethylene vinyl acetate eva sole. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

The most popular soles are ethylene vinyl acetate. Higher quality eva will have a higher percentage of vinyl acetate while eva with very little vinyl acetate can be hard brittle and feel like cardboard. Eva technicaly named ethylene vinyl acetate eva is one of the best shock absorption materials available today.

The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material. It is a plastic made by combining ethylene and vinyl acetate to create rubber like properties which can be used for shoe soles. It is also referred to as polyethylene vinyl acetate a compound known as a copolymer of vinyl acetate and ethylene. Ethylene vinyl acetate is simply a soft plastic it s the foaming process or blowing of eva that makes it perfect for a shoe midsole.

Eva outsole is the lightest among all kinds of outsoles. Eva stands for ethylene vinyl acetate. Eva technicaly named ethylene vinyl acetate eva is one of the best shock absorption materials available today. This is why all the major top line brand joggers use this material due to the great combination of shock absorption with the light weight of the sole.

Ethylene vinyl acetate eva is made from two compounds vinyl acetate and ethylene. The feature of eva sole. Eva or ethylene vinyl acetate sometimes known as peva poly ethylene vinyl acetate is a polymer based material consisting of ethylene and vinyl acetate merged together a copolymer.
