Abstract

The present invention relates to formed articles, such as medical devices, made of an thermoplastic polymer material, which comprises at least one of thermoplastic polymer A, selected from cyclic polyolefins; aliphatic polyamides, aliphatic polyurethanes and halogenated polyolefins, and a method for their UV disinfection and/or sterilization, including disinfection and/or sterilization of the inner surface of the formed article. The inventive method for UV sterilization comprises the exposure of the outer surface of the formed article with UV radiation at a wavelength in the range of 260 nm to 300 nm, wherein the thermoplastic polymer material has a transmittance of at least 10 %, averaged over the wavelength range from 260 nm to 300 nm, measured in accordance with ISO 13468-2 at a thickness of 3 mm.
