Elkem introduces new biocompatible, electro conductive SILBIONE? Liquid Silicone Rubber for advanced healthcare devices

On October 23, Elkem ASA 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 biocompatibility, 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 biocompatibility1?properties the market demands¡ªwhile 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 ¡ª supporting competitiveness, performance and sustainability goals.
