device, enabling overall size reduction and creating more space for other components. The Vectra MT LCP range includes glass rein-
Vectra grades can provide extraordinarily easy flow and low warpage,” it says – ideal properties for highly complex designs. Celanese cites the case study of a disposable medical wearable injection device, where the high flow of its LCP, together with its CAE insights, enabled thinner wall design for improved end-user experience and reduced system cost (see bar chart). The customer, which was already making a device using components in polycarbonate, wanted higher mechanical performance, including dimen- sional stability, high stiffness and tight part toler- ances for the internal chassis. It also wanted to use moulds with more cavities, and to cut cycle times. Vectra MT LCP delivered up to 50% per part cost
savings, Celanese says. It could also be processed with shorter cycle times and allowed the moulder to build a tool with an increased number of cavities. Finally, it provided the required stiffness with very thin walls, which freed up space in the
forced, mineral-filled, higher-flow, tribologically modified and appearance grades, suitable for a variety of uses in medical device applications, particularly in wearable injection devices, Celanese says. It complies with regulatory requirements, including FDA – it is listed in Drug Master File DMF 8464, and Device Master File MAF 315 – and meets the requirements of US Pharmacopeia Class VI and ISO-10993 covering biocompatibility, as well as corresponding European Union and national regulatory registry requirements. At the beginning of the year, Polyplastics, which is a joint venture between Celanese (45%) and Daicel, introduced Duracon PM09S01N, its first acetal for drug contact and delivery applications for the medical and healthcare market.
