I'm reaching out as a representative of a medical device company in Montreal, where we're working on a disposable inflatable vaginal balloon device designed to maintain internal air pressure (~8 psi) for up to 14 days at a temperature of 38°C. We've experimented with various materials like TPU, PVC, and EVA-EVOH blends, but we've encountered challenges with pressure retention and discoloration. We're eager to explore alternative materials that could offer better performance. We're specifically interested in biocompatible films within the 15–20 mil thickness range, focusing on options with low oxygen permeability, excellent thermoformability, and strong seal integrity. It would be great to discuss potential off-the-shelf solutions, particularly any PU/PVDC or PVC/PVDC films you may have. Looking forward to your insights and any technical details you can provide!
