The development of this application would not have been possible without the close collaboration of Balda Group, Roche Diabetes Care, and DuPont

Roche Diabetes Care, the world’s leading company in diabetes management, selected low-friction DuPont™ Delrin® acetal homopolymer from DuPont Performance Materials (DPM) for its renowned insulin placement assistant named the Accu-Chek® LinkAssist Plus.

The Accu-Chek® LinkAssist Plus insertion device helps to insert an infusion set easily and virtually pain free, even at hard to reach places on the body. Its integrated safety release prevents accidental insertion.

The excellent flow characteristics of Delrin®, in conjunction with its good dimensional stability and mechanical properties, make it the ideal material for producing small and thin parts that are both cost-effective and create minimal waste in the manufacturing process. “In this application, the low friction characteristics and spring-like behavior of Delrin® contribute to the smooth and fast operation of the device, which has four key components in the mechanism -wing front, primer, latch lock and slider-” ensures Laurent Hanen, Healthcare Segment Leader at DuPont Performance Materials.

The development of this application would not have been possible without the close collaboration of Balda Group, Roche Diabetes Care, and DuPont. André Nadrowski, Product Manager at Balda Medical GmbH and Co.KG states, “In the healthcare industry, products need to meet high standards in the areas of quality, reliability and performance. This is why we have decided to go with DuPont™ Delrin®, as it features excellent friction performance, spring effect, and molding capabilities. DuPont’s expertise in product knowledge and application development was key in this program as it enabled us to meet Roche Diabetes Care’s stringent requirements and deadlines.”

Depending on the specific application, DuPont can deliver an appropriate solution from either its broad range of standard products, or from its portfolio of “Special Control” (SC) and “Premium Control” (PC) grades. These SC and PC grades are differentiated by having a greater degree of testing, manufacturing control and regulatory support. These are also compliant with USP Class VI, ISO 10993-5 and -11 standards, and are manufactured according to Good Manufacturing Practice (GMP) guidelines.
