James Cropper Advanced Materials has announced that its OPTIVEIL range of lightweight polyester veils has passed critical medical testing, confirming its safety for human contact and opening the door for applications in wearable medical devices.

The materials underwent an in vitro cytotoxicity study in line with ISO 10993-5 and were tested under ISO/IEC 17025:2017 laboratory conditions. The polyester veil passed all requirements, demonstrating no adverse cellular reactions and confirming its suitability for medical use.

Dr. Mandy Clement, Innovation Director at James Cropper, said: This successful certification marks a significant milestone in our journey to support innovation in healthcare. Our OPTIVEIL polyester veils are now validated for use in sensitive medical environments, including wearable technologies.

The OPTIVEIL range offers skin-friendly, breathable, and durable properties, making it well-suited for long-term wear in medical devices such as biosensors, therapeutic patches, and smart bandages. Its uniform thickness and flexibility support adhesive patch production, while its mechanical strength and chemical resistance enhance durability and patient comfort.

James Cropper will showcase the OPTIVEIL range alongside its broader portfolio of advanced nonwoven veils at CAMX 2025 in Orlando, Florida (8 11 September, Booth B37), highlighting its role in advancing materials for healthcare, aerospace, automotive, and renewable energy industries.
