Selecting Polymers for Medical Devices based on Thermal Analytical Methods

摘要

This biomaterials overview for selecting polymers for medical devices focuses on polymermaterials, properties and performance. An improved understanding of thermoplastics and thermosetproperties is accomplished by thermal analysis for device applications. We will discuss the medicalapplications and requirements as well as the oxidative and mechanical stability of currently usedpolymers in devices. The tools used to aid the ranking of the thermoplastics and thermosets are DSC,TGA, TMA and DMA as well as a number of key ASTM polymer tests. This presentation will spotlightthe thermal and mechanical characterization of the bio-compatible polymers e.g., olefins, nylon,polyacetals, polyvinyl chloride and polyesters.
