Ethylene Vinyl Acetate Shoe Sole

It is a plastic made by combining ethylene and vinyl acetate to create rubber like properties which can be used for shoe soles.

Ethylene vinyl acetate shoe 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. Ethylene vinyl acetate eva is made from two compounds vinyl acetate and ethylene. 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. Eva outsole is the lightest among all kinds of outsoles.

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. Eva technicaly named ethylene vinyl acetate eva is one of the best shock absorption materials available today. Eva stands for ethylene vinyl acetate.

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. The most popular soles are ethylene vinyl acetate. That is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

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

The material comprises the following components in parts by weight. It is also referred to as polyethylene vinyl acetate a compound known as a copolymer of vinyl acetate and ethylene. 921 1 20 1 n.
