Polyethylene-co-vinyl acetate 70:30 (wt) [24937-78-8]
Polyethylene-co-vinyl acetate (PEVA) is a highly biocompatible polymer used in a wide variety of biomedical
device applications including drug delivery systems and medical implants . PEVA has many desirable
characteristics (tensile strength, barrier properties, controlled release and optical transparency) . Our PEVA
is a highly purified copolymer with no processing additives and a low polydispersity index . PEVA can be
processed in a large number of ways including spin coating, casting, molding, extrusion and a variety of
emulsion and solution mixing . Polysciences Inc . can synthesize custom ethylene:vinyl acetate ratios and
molecular weights, please use our custom inquiry form for more information .
