DELRIN® CASE STUDY Delrin® reduces risk of failure in surgical devices A leading surgical equipment producer replaced PC/ABS with Delrin® to enhance the strength and impact toughness of handle components. What did the customer gain from Delrin® • Resistance to 75% alcohol disinfectant, ensuring no environmental stress cracking. • Enhanced impact toughness to pass 1m device drop testing from four angles. • High strength to withstand long-term loading without need of glass reinforcement. • Exact dimensions for superior fit and function of parts. • Excellent fatigue resistance to endure >10,000 reciprocating cycles. • Good property retention following high-temperature steam sterilization. • Cost-effective and easy to process versus other alternatives, such as PPSU. Delrin® is an industry-leading premium industrial polymer business. Grounded in strong innovation, Delrin is a category creator with a longstanding reputation for quality, reliability, supply and product performance. The iconic Delrin brand, coupled with proprietary technology and deep application expertise, make us a leader in the high-end engineering polymer market. Delrin has excit- ing growth prospects from exposure to automation, actuation, healthcare, mobility and consumer applications.
