General description
Poly(vinyl alcohol-co-ethylene) (PVA-co-PE) is a hydrophilic non-toxic polymer with good film forming ability. Its other properties include biocompatibility, high tensile strength and low fouling potential.
Application
PVA-co-PE can be used in the formation of nanofibrous membranes for the development of high performance adsorption materials. It can also be used to form membranes for potential applications such as lithium ion batteries, biosensors and microfluidic devices.
Other Notes
Maximum working temperature 240°C

Ethylene vinyl alcohol (EVOH) is one of the best known flexible thermoplastic oxygen barrier materials in use today. It is especially important for refrigerated and shelf-stable foods where oxygen deteriorates the quality of packaged products and reduces their shelf life.
