Can silicones provide low trauma adhesion for medical applications?

When adhesion is low, the dressing, bandage, or device in use won’t stay in place; too high, and problems are encountered upon removal. As design engineers work on new wound care dressings, long-term bandages, or appliances, like ostomy appliances, electrodes, or other stick-to-skin devices, it is important to match the right materials and adhesives to the application. The goal is adequate adhesion levels during device attachment, and low mechanical trauma during removal. 3M’s new silicone adhesives for stick-to-skin applications provide a low/no trauma solution for medical. Working with these materials requires the involvement of an experienced medical converter, like Fabrico, who can recommend different adhesives and materials to meet design specifications.

    1. At Fabrico, we offer a selection of low trauma adhesives for wound care and drape applications, including acrylics, hydrocolloids, hydrogels, and silicones. The new soft silicones require close attention during the converting process, but offer skin-sensitive characteristics for multi-layer, multi-lamination wound care dressing components. As an experienced converter, Fabrico can help design engineers select the appropriate release liners for soft silicones, and convert them using dedicated dies, over wrap protection for contact surfaces, and thorough cleaning at change-over. The result is wound care components and products that adhere securely, and can be re-positioned and removed gently at the end of treatment.

    1. 3M Medical Specialties has introduced a new silicone adhesive tape platform for stick-to-skin applications to provide a low/no trauma alternative for medical OEMs and contract manufacturers. We have developed these silicone adhesive tapes so that they hold the device or wound care dressing in place securely for the duration of the treatment, but can be repositioned or even removed to shower, and then completely and gently removed when treatment ends. Opportunities for gentle silicones include protection, treatments, rehabilitation, monitoring and testing, especially for neonatal and geriatric applications. The adhesives provide good tack and adhesion, are available in a range of tape backings, and are tin, platinum, and peroxide-free.
