(IN BRIEF) At COMPAMED 2025, WACKER introduces several groundbreaking silicone solutions aimed at redefining medical adhesive and tubing performance while advancing environmental goals. The main attraction is SILPURAN® eco 2114, a biomethanol-based silicone gel adhesive produced under mass balance certification that cuts carbon emissions during manufacturing by up to 28%, without compromising compatibility or quality. The product is designed for use on sensitive skin, ideal for medical wearables, wound care, and fixation devices. In addition, a new study from WACKER’s research center highlights the suitability of silicone gels for transdermal drug delivery systems, demonstrating their superior ability to release a variety of active ingredients, with customizable release profiles. WACKER will also showcase two silicone elastomer grades—ELASTOSIL® R plus 4360 and R plus 4366—engineered for pharmaceutical tubing applications. Both offer high purity, biocompatibility, and durability, with the latter featuring a low-friction surface for peristaltic pumps. These innovations reinforce WACKER’s commitment to sustainable, high-performance solutions for modern therapeutic and medical applications.

(PRESS RELEASE) MUNICH, 17-Nov-2025 — /EuropaWire/ — WACKER is unveiling a suite of cutting-edge silicone innovations at COMPAMED 2025, showcasing its leadership in medical technology and sustainability. Among the highlights is SILPURAN® eco 2114, the company’s first silicone gel made using biomethanol, offering a significant reduction in carbon emissions. As calculated by the global warming potential of its emissions, this eco-conscious gel reduces CO₂ output during production by up to 28 percent compared with its conventionally produced equivalent. Despite its greener footprint, SILPURAN® eco 2114 delivers the same robust performance expected of WACKER’s silicone adhesives, ensuring a seamless transition for manufacturers seeking more sustainable options.

In a recent study, WACKER examined the release profiles of its silicone gel adhesives for transdermal patches. The result: silicone gels are able to release active ingredients such as Retinol much more effectively than conventional products (see graphic).

The new adhesive is designed for sensitive medical uses, including wound dressings, wearable devices, and plasters. Its two-part, addition-curing formula sets into a gentle, transparent gel that bonds securely while allowing for painless removal—ideal for chronic wound care or fragile skin. Produced with biomethanol under a REDcert²-certified mass balance scheme, the product doesn’t require new processing methods, as it mirrors the performance and specifications of fossil-based silicone gels.

Another significant showcase is WACKER’s recent study on transdermal silicone gel adhesives, conducted by the company’s Healthcare Competence Center in Ann Arbor (USA). By using a Franz diffusion cell, researchers measured how silicone gels can deliver a range of active compounds—including over-the-counter therapies, anti-inflammatories, herbal substances, and vitamins. The results reveal these silicone matrices not only release active agents at higher rates compared to traditional adhesives but also support customizable delivery profiles—from steady release to delayed bursts—offering new possibilities for next-generation topical delivery systems. As Dr. Ufuk Karabiyik, who leads the research team, notes, silicones are evolving beyond passive carriers into highly functional components enabling precise, skin-friendly drug delivery.

WACKER is also spotlighting high-performance elastomer grades for medical tubing: ELASTOSIL® R plus 4360 and ELASTOSIL® R plus 4366, both of which are designed for demanding pharmaceutical and therapeutic environments. These silicone rubber products, with their platinum-catalyzed curing systems, offer high purity and consistent performance, making them suitable for heart-lung machines, dialysis equipment, infusion pumps, and even vaccine dispensing. ELASTOSIL® R plus 4366 in particular features a specially engineered low-friction surface, reducing wear during pumping cycles and extending service life—an essential attribute for peristaltic pump tubing.

Together, these innovations underscore WACKER’s commitment to sustainability, precision, and high-quality medical polymer solutions. Visitors can explore these advancements firsthand at the company’s booth in Hall 8A, Booth G04 at COMPAMED in Düsseldorf from November 17 to 20, 2025.
