| his study was divided into two parts. Part 1 dealt with finding an alternative material for PVC used in medical applications. Flexible polyolefins (FPOs) were selected for this purpose, because polyolefins have a history of biocompatibility.;Two grades of FPO were selected for this purpose (W105 and W116) due to their high softening temperature required for sterilization. These FPOs were tested for mechanical properties such as tensile, toughness, tear strength, and Young's modulus. Oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) were tested for permeation characteristics of the material.;FPOs were found to have better physical properties and comparable barrier properties at a lower thickness than the PVC films.;Part 2 examined the oxidation effectiveness of two biological antioxidants, ;Virgin FPO was used as the control; it was processed on a single screw extruder like other formulations to maintain a similar heat history. Oxidative Induction Time test (OIT) scan was run for all formulations per ASTM D-3895.;The OIT results showed that... |
