DuPont Premieres Liveo C6-8XX Liquid Silicone Rubber Series

DuPont has launched Liveo C6-8XX Liquid Silicone Rubber (LSR), a new USP Class VI (C6) series of medical-grade, two-part silicone elastomers engineered to meet stringent medical device requirements.

The Liveo C6-8XX LSR series delivers precision, reliability, and processing efficiency for healthcare applications, particularly medical device fabrication. Featuring improved rheology and lower viscosity, these materials enable faster and more consistent molding cycles, as well as processing flexibility, making them ideal for fully automated production environments, according to DuPont.

Designed for high heat stability, sterilization through multiple methods, and proven biocompatibility, the new LSR series supports the development of safe, high-quality, complex medical devices, including non-implant and short-term implant healthcare components. The series includes five products representing a range of hardnesses from 30 to 70 Shore A: Liveo C6-830 LSR, Liveo C6-840 LSR, Liveo C6-850 LSR, Liveo C6-860 LSR, and Liveo C6-870 LSR.

“DuPont Liveo C6-8XX Liquid Silicone Rubber has been engineered to provide flexibility and reliability for medical device manufacturers,” said Mateo Chirinos Palacios, global product marketing manager for DuPont Healthcare Solutions. “With better flow during molding and a pot life of greater than three days, this new LSR series enables improved processability and more complex designs, among many other benefits.”

The new medical-grade product series meets USP Class VI and select EP regulatory requirements, complies with REACH SVHC (< 0.1% w/w) requirements, and is tested according to ISO 10993 standards. Liveo C6-8XX LSRs are manufactured under ISO 9001, 14001, and 13485 certifications to provide the highest quality and reliability for healthcare applications.

Supplied in two-component kits, Liveo C6-8XX Liquid Silicone Rubber materials complement precision molding and automated systems, helping OEMs achieve efficiency without compromising safety or performance.
