James Cropper Advanced Materials’ (Schenectady, N.Y., U.S.) Optiveil range of lightweight polyester veils has successfully passed critical medical testing, confirming its safety for human contact and suitability for use in wearable medical devices.
The company’s surface veil technology finds application in a diverse range of industries and specific components — from aerospace to wind energy to marine — and are often used to achieve a high-quality, resin-rich surface finish on composite parts. Now, with this new certification, Optiveil veils are ready to be incorporated into next-gen medical products, offering manufacturers a trusted and versatile material that meets the demands of both clinical environments and patient care.
The materials underwent an in vitro cytotoxicity study in accordance with ISO 10993-5, the international standard for biological evaluation of medical devices. Conducted under ISO/IEC 17025:2017 laboratory conditions, the study assessed the potential for cytotoxic effects from direct contact with the polyester veil. The veil passed all testing criteria, demonstrating it does not cause any adverse cellular reactions.
“This successful certification marks a significant milestone in our journey to support innovation in healthcare,” says Dr Mandy Clement, innovation director at James Cropper. “Our Optiveil polyester veils are now validated for use in sensitive medical environments, including wearable technologies.”
Optiveil’s skin-friendly, breathable and durable properties make them ideal for long-term wear in medical devices. The veil’s uniform thickness and flexibility aid the production of pressure-sensitive adhesives and adhesive patches, while its mechanical strength enables integration with embedded electronics, in devices such as biosensors, smart bandages and therapeutic patches. The material also demonstrates optimal breathability and chemical resistance enhancing both patient comfort and durability.
James Cropper Advanced Materials will be exhibiting the Optiveil range and a wider portfolio of advanced nonwoven veils at CAMX 2025.
