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.

Ethylene vinyl acetate shoe sole.

The most popular soles are ethylene vinyl acetate. The material comprises the following components in parts by weight. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. 40 60 parts of eva 7350 20 40 parts of white carbon black 5 15 parts of poe polyolefin elastomer 8003 rubber particle 5 15 parts of industrial calomel 1 5 parts of foaming agent 0 2 0 6 part of.

The feature of eva sole. It is also referred to as polyethylene vinyl acetate a compound known as a copolymer of vinyl acetate and ethylene. The invention discloses a light weight eva ethylene vinyl acetate shoe sole material and a preparation method thereof. 921 1 20 1 n.

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. That is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. Ethylene vinyl acetate eva is made from two compounds vinyl acetate and ethylene. Eva technicaly named ethylene vinyl acetate eva is one of the best shock absorption materials available today.

Eva outsole is the lightest among all kinds of outsoles. 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.

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. Eva technicaly named ethylene vinyl acetate eva is one of the best shock absorption materials available today. Eva is now the most widely used midsole material for shoes. The cushioning of ethylene vinyl acetate shoes was diminished after 500 km compared with that at 0 km 968 0 25 9 n vs.

Eva stands for ethylene vinyl acetate. 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. 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.
