Method for sterilization of formed articles made of acrylic-based polymers

Formed articles, such as medical devices, can be made of an acrylic-based polymer material, which contains at least one polyalkyl(meth)acrylate. A method can be used for the UV disinfection and/or sterilization of the formed articles, including disinfection and/or sterilization of the inner surface of the formed article. The method for UV sterilization involves 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 acrylic-based 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.
