- Compounds Wear and Friction Solutions Medical Devices
For a medical device, whether it be a drug delivery pen or a laparoscopic surgical tool, repeatable and efficient motion is critical to performance. The friction between moving parts plays a large role in how a device is perceived and accepted by both consumers and healthcare professionals. LUBRICOMP™ and LUBRILOY™ compounds can help deliver the performance required.; Growing List of Demands; The demands on wear and friction materials for medical devices grow as sterilization and cleaning techniques evolve, parts get smaller and thinner, and market trends move towards more consumer friendly styling and colors. Add the heightened emphasis on system cost optimization and the need for innovative internally lubricated thermoplastic solutions expands.; Internally Lubricated Compounds; The addition of an internal lubricant to a thermoplastic material can reduce the coefficient of friction between two plastic parts, allowing them to slide past each other smoothly with minimal wear. Traditional lubricants like medical grade silicone and PTFE can be combined with advanced PC copolymer technology to deliver the required performance in thin wall parts.
