Definition: Nano clay particles can be added to medical plastics in low loadings to improve rigidity while preserving elongation and surface finish. This is advantageous in thin wall applications, such as catheters which require improved rigidity for pushability. These non-organic, platelet-shaped particles can also improve barrier, thermo-mechanical, flame resistance and processing properties of medical polymers.
Purpose:Â Provide a basic understanding of nano clay particle additives and demonstrate property enhancements achievable when added to medical polymers at various loadings.
