Elkem’s SILBIONE™ LSR Select EC 70 delivers conductivity, biocompatibility, and molding precision for advanced wearable and diagnostic healthcare devices.
Elkem ASA, a global innovator in silicon-based advanced materials, has launched its latest breakthrough — SILBIONE™ LSR Select EC 70, a medical-grade liquid silicone rubber engineered to power the next generation of healthcare technologies. This advanced elastomer is specifically designed for use in wearable, diagnostic, and electronic medical devices, combining three critical features: high electrical conductivity, certified biocompatibility, and optimized processing performance.
According to Michael Goglia, Healthcare Business Manager at Elkem, this new product represents a significant milestone in the advancement of conductive elastomeric materials for medical applications. “SILBIONE™ LSR Select EC 70 marks a major step forward in the development of conductive elastomeric components for medical devices,” he said. “Through years of research and close partnerships with OEMs and molding specialists, we’ve created a material that meets the market’s growing need for conductivity, elasticity, and proven biocompatibility — while being fully compatible with existing liquid injection molding systems.”
With a resistivity below 10 ohm-centimeters, SILBIONE™ LSR Select EC 70 provides the precise electrical performance required for wearable health monitors, flexible sensors, and electronic diagnostic tools. Its liquid form supports complex geometries and fine detailing, enabling designers to produce compact, durable, and high-performing medical components. The material’s superior elongation and mechanical stability ensure consistent performance under the stresses of continuous wear and environmental exposure.
Elkem’s new silicone has been rigorously tested and has passed ISO 10993-5 cytotoxicity and ISO 10993-10 skin sensitization standards, affirming its safety for contact with human skin. This makes it particularly suited for prosthetics, biosensors, flexible circuitry, and next-generation diagnostic platforms that require both electrical functionality and patient safety.
A key advantage of SILBIONE™ LSR Select EC 70 lies in its compatibility with Elkem’s proprietary LSR Select™ platform — a patented technology that enables manufacturers to control cure kinetics directly within the mold. This innovation allows precise adjustments during processing, resulting in faster cycle times, reduced material waste, and improved production efficiency. As a result, device manufacturers gain a sustainable, high-performance solution that aligns with both regulatory and environmental standards while maintaining manufacturing flexibility.
Now commercially available, SILBIONE™ LSR Select EC 70 positions Elkem at the forefront of materials innovation for healthcare electronics, helping bridge the gap between biocompatibility and smart medical functionality. By combining precision molding control, electrical reliability, and patient safety, the company continues to redefine what is possible in the design and production of modern healthcare devices.
