Estimated reading time: 1 minute

Elkem ASA, a global leader in advanced silicon-based materials, unveiled SILBIONE LSR Select EC 70, a next-generation medical-grade liquid silicone rubber. Designed for wearable and diagnostic devices, the material combines high electrical conductivity, certified biocompatibility1, and enhanced process control, setting a new standard for precision healthcare applications.

"SILBIONE LSR Select EC 70 marks a major step forward in the development of conductive elastomeric components for medical devices," said Michael Goglia, Elkem's healthcare business manager. "After years of development and close collaboration with molding partners and OEMs, we're proud to offer a material that delivers the conductivity, elongation and biocompatibility properties the market demands—while running seamlessly on existing injection molding equipment."

With resistivity below 10 ohm-centimeters, this new material offers ideal conductivity for wearable devices, flexible electronics and advanced sensors. Its liquid injection moldable form enables intricate designs, while its durability and flexibility ensure long-term performance in demanding environments. The material also offers proven biocompatibility, having successfully passed ISO 10993-5 cytotoxicity and ISO 10993-10 skin sensitization tests, making it well suited for applications such as prosthetics, diagnostic tools, and next-generation flexible circuits.

Now commercially available, the innovation has been specifically engineered to be used with LSR Select, Elkem's patented liquid silicone rubber technology designed for precision liquid injection molding. This unique system enables manufacturers to fine-tune cure kinetics directly in the mold, offering greater control, faster cycle times, and reduced waste — supporting competitiveness, performance and sustainability goals.
