EVAs are divided into three categories based on the weight percent of vinyl acetate available. The first category is a type of polyethylene containing about 4% vinyl acetate, or polyethylene modified with vinyl acetate. This material, which is generally non-toxic, is suitable for film production because of its flexibility and gloss.
The second group are copolymers with a weight percent of vinyl acetate ranging from 4 to 30% and are a type of thermoplastic elastomer. The most commonly used group of EVA materials is adhesives. Another type of material contains more than 40% vinyl acetate, known as ethylene vinyl acetate.
One of the major uses of EVA is the production of EVA glue, shoe soles, and so on.
Other uses of this material include use in medical engineering as a drug dispenser and use in the manufacture of orthopedic appliances. The thin and flexible foams used in the art of flower making to make artificial flowers are EVA.
These materials are usually marketed as EVA granules in 25kg packages.
