Arkema Adds Two New EVOH Grades to its Range of Barrier Polymers

Published on 2014-06-25. Author : SpecialChem

Arkema expands 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. Evasin® 4405F and Evasin® 4451F differs by their melt flow index, as showed in the table below.

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.

Since 2009, Arkema is the exclusive distributor for Evasin® EVOH in Europe and has become the only resin supplier able to offer both Orevac® tie layer and Evasin® EVOH barrier material. Arkema is now able to offer full solutions to all of its customers producing multilayer barrier films.

Evasin® is a trade name registered by Chan Chung Petrochemicals Co.Ltd. Chang Chun Petrochemicals Co.Ltd is one of the largest Taiwanese chemicals manufacturer with a strong activity in intermediates, epoxys, aromatics, and particularly Vinyl Acetate (VAM), Polyvinyl Alcohol (PVA), and Ethylene - Vinyl Alcohol (EVOH) copolymers.
