General Description |
Ethylene vinyl alcohol (EVOH) is formally a copolymer of ethylene and vinyl alcohol. It is a hydrophilic, non-toxic polymer known for its flexibility, transparency, and good film-forming ability. EVOH exhibits properties such as biocompatibility, high tensile strength, and low fouling potential. |
|
Uses |
Packaging Films: EVOH is commonly used in packaging films due to its excellent barrier properties against gases such as oxygen, carbon dioxide, and moisture. It helps extend the shelf life of packaged food products by preventing spoilage and preserving freshness. Nanofibrous Membranes: EVOH can be used in the formation of nanofibrous membranes, which are utilized in various applications such as filtration, separation, and adsorption. These membranes offer high performance in capturing and removing contaminants from liquids and gases. |
