Arkema extends its range of barrier polymers with two new EVOH grades of high ethylene content
These two new Evasin® EVOH grades contain 44% of ethylene. The high ethylene content brings an 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 differ by their melt flow index, as shown in the table below.
|Melt index 210 °C, 2.16 kg (g/10min)||Melting point (°C)||O2 Transmission rate 65% RH, 20 °C*|
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 the multilayer food packaging, automotive fuel tank and heating pipe markets.
Since 2009, Arkema has been 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 manufacturers with a strong activity in intermediates, epoxys, aromatics, and particularly Vinyl Acetate (VAM), Polyvinyl Alcohol (PVA), and Ethylene - Vinyl Alcohol (EVOH) copolymers.
