Ethylene copolymers

  • Ethylene can be copolymerized with a number of other compounds.
  • Ethylene-vinyl acetate copolymer (EVA), for instance, is produced by the copolymerization of ethylene and vinyl acetate under pressure, using free-radical catalysts.
  • Many different grades are manufactured, with the vinyl acetate content varying from 5 to 50 percent by weight.
  • Ethylene Copolymer based hot-melt are widely used in packaging, for various applications including cartons and folding boxes, deep-freeze packages or bottle labelling.
