Plastic materials offer opportunities and play an increasingly vital role: colors aid identification and automated laboratory processes while functional additives expand the usable property window of the polymer in areas such as surface chemistry or oxygen protection. Processing conditions can cause material properties to shift from the values stated in the information. It is the responsibility of the medical device manufacturer and the person placing the medical device on the market to ensure compliance of the medical device with all applicable laws and regulations, including the suitability of all raw materials and components used for its manufacture.
