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 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.
