Ethylene Vinyl Acetate

Ethylene-Vinyl Acetate is a Commodity Polymer that is a copolymer of Ethylene and Vinyl Acetate. EVA copolymer is classified into three categories according to Vinyl Acetate content present. The first type is EVA containing low VA percentage. This category of Ethylene-Vinyl Acetate is used as a Thermoplastics Material. The second type of EVA consists of 4% to 30% of VA and it is used as a Thermoplastic Ethylene-Vinyl Acetate. The third category of Ethylene-Vinyl Acetate consists of more than 40% VA and it is used as Ethylene-Vinyl Acetate Rubber. The process of manufacturing Ethylene-Vinyl Acetate involves a method wherein Ethylene and Vinyl Acetate are continuously polymerised. This continuous polymerisation is performed in a Polymerising Vessel. 

Usage

Ethylene-Vinyl Acetate has extensive applications in Biomedical Engineering where it is used as a Drug Delivery device. EVA is also known as Expanded Rubber or Foam Rubber. It is used as padding for sports equipment like Ski Boots, Bicycle Saddles, Hockey Pads, Gloves, helmets, etc. The Photovoltaics Industry also uses Ethylene-Vinyl Acetate as an Encapsulation Material for Crystalline Silicon Solar Cells. Other common uses of EVA include in Footwear Components, Flexible Hoses, Automobile Bumpers, Toys and Athletic Goods, Moulded Automotive Parts, Flexible Packaging, Films, etc. The Food Industry also uses Ethylene-Vinyl Acetate for various food packaging applications like Seafood and Meat Packaging, Beverage and Food Packaging Design, Dry Food, and Snack Packaging, Dairy and Cheese Packaging, Plastic Closures for Beverages, Vacuum Packaging, Barrier Shrink Bags, Case Ready Meat Packaging, etc.
