I think Wikipedia will give you a better answers than me-"Ethylene vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene.
." (quoted from Wikipedia)
Then why It can be the good choice for shoes bottom? I think here I need to introduce some chemical traits of EVA so that my artical could be more understandable to all of you.
It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive water proof properties, and resistance to UV radiation. it has little or no odor and is competitive with rubber and vinyl products in many electrical applications.
So, in a word , if we make EVA a part of our shoes bottom,then we can make our shoes more elasticable and suitable.
So, which places are now producing EVA outsoles in a mass? Where to buy EVA outsoles for Factory?
In the early 21 century,actually the late 20 century, South East Asia became the most integrated place of making shoes , By the way ,Anta, Lining,Xtep came up and flourished in China those days.
Like China ,India ,Thailand and other South Eastern Asia countries, they benifited from the growing global economy and open up rform , their outsoles products go to the world too.And most importantly their outsoles products became famouse for their moderate price and good quolity.
