The application of polymers in medical devices is often challenging. Besides meeting highest quality standards, materials need to withstand aggressive disinfectants, pharmaceuticals and resist different sterilization procedures without sacrificing mechanical performance. Furthermore, it needs to be ensured that no harmful interaction takes place among the material and any bodily tissue or fluids. Moreover, any reaction with pharmaceutical formulation needs to be avoided to prevent changes in the composition and activity of the active ingredients. Not least, materials for medical applications need to exhibit an excellent processability in order to realize delicate geometries for minimal invasive devices or accurate fit of connecting parts.
A proper material selection is a crucial step in the development process of medical devices. Materials need to meet the highest quality standards, resist harsh chemicals & pharmaceuticals, and fulfill critical performance requirements which need to be maintained after sterilization.
RIGHT POLYMER FOR EACH APPLICATION
We offer a variety of materials under the Care brand – from transparent to translucent, from elastic to strong, from unmodified to stabilized, filled or functional.
