Absorption Behavior of Polyamide 6 (PA6) when Exposed to Different Environments

This study explores the behaviour of polyamide when exposed to saline solution and drying conditions. Polyamide is widely used material in many different industries such as medical devices, textile, packaging, electronics etc. In many of those applications exposure to different
saline like or bodily fluids and different humidity conditions is common. Saline solution was used in this study as a medium to simulate bodily fluids in laboratory conditions. Two series of polyamide 6 (PA 6) samples were produced with one series being immersed in sali
ne solution and the other exposed to drying in containers with hygroscopic material. Both series of samples were exposed in described conditions for 28 days. The principle for determining absorbed and desorbed medium during the treatment period is described in detail. Results of presented study provide insight into polyamide 6 absorption behaviour that is crucial for understanding the durability and reliability of polyamide - based products, especially those in biomedical applications
