Barrier polymers with two new EVOH grades of high ethylene content

25-Jun-14

Arkema has expanded its product range of Evasin® EVOH (Ethylene vinyl alcohol) copolymers with two new grades containing 44% of ethylene. Arkema now offers a wide range of EVOH from 29% to 44% ethylene content that can be used for most barrier films applications. These two new grades of Evasin® EVOH contains 44% of ethylene. The high level of ethylene brings excellent balance of barrier properties and processing stabilities. These grades can be processed by single-bubble or double-bubble blown film extrusion for heat shrink applications. EVOH is a specialty copolymer with very high barrier properties to gas (oxygen, carbon dioxide), aromatics and hydrocarbons. These characteristics, together with excellent transparency and good processability, have made this the reference product among barrier polymers, in particular for multilayer food packaging, automotive fuel tank and heating pipe markets.
