By contrast, standard PVC films often trap moisture, leading to maceration in 48\u201372 hours.&lt;br ?--> Medical-grade TPU (such as that produced by <strong>Shanghai Xin Gen Tech<\/strong>) passes <strong>ISO 10993 biocompatibility testing<\/strong> and is <strong>FDA-listed<\/strong>, ensuring zero cytotoxicity and skin irritation. This is critical for transdermal applications where the film is in direct contact with compromised skin for days.<\/p>\n<p style=\"line-height: 2.25em; font-size: 15px; color: #3e3e3e; text-align: left; text-indent: 0.5em; margin: 1em 0px; visibility: visible;\"><strong>Case in point:<\/strong> A leading Chinese wound care manufacturer switched from PU foam to a TPU film laminated with a silicone adhesive for their advanced wound dressing line.
