DuPont Introduces Liveo C6-8XX High Heat Silicone Rubber for Medical Device Innovation

DuPont de Nemours, Inc. has unveiled its new Liveo C6-8XX Liquid Silicone Rubber (LSR) series, marking a significant advancement in medical-grade silicone elastomer technology. This medical-grade formulation delivers superior performance specifically designed for high heat silicone applications, making it ideal for complex healthcare device manufacturing. The new product line demonstrates how advanced materials can enhance both safety and production efficiency in the medical device sector.

Advanced Medical-Grade Formulation with Superior Thermal Performance

The Liveo C6-8XX series represents a breakthrough in high heat silicone technology, engineered to meet the stringent requirements of medical device applications. What sets this product apart is its exceptional thermal stability combined with improved rheological properties that enable faster and more consistent molding cycles. The two-component LSR system features significantly lower viscosity compared to conventional formulations, offering manufacturers greater processing flexibility without compromising material integrity. The superior heat management capabilities make it well-suited for sterilization processes and long-term healthcare applications where thermal resistance is critical. USP Class VI (C6) compliance ensures the material meets the highest biocompatibility standards for direct and indirect human contact applications.

Comprehensive Product Line and Regulatory Compliance

The Liveo family comprises five distinct products with Shore A hardness levels ranging from 30 to 70—specifically the C6-830, C6-840, C6-850, C6-860, and C6-870 variants. This diverse hardness spectrum allows medical device manufacturers to select the optimal material for their specific application requirements, whether for flexible components or rigid structures. All products meet rigorous regulatory standards including USP Class VI certification and select European Pharmacopoeia (EP) requirements. The entire series has been manufactured under ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 13485 (medical device quality) certifications, ensuring consistent quality and reliability across production batches.

Optimized for Precision Manufacturing and Automated Production

A key advantage of the Liveo C6-8XX series is its compatibility with fully automated manufacturing environments. The enhanced flow characteristics and consistent processing behavior significantly reduce cycle times while maintaining dimensional precision—critical factors for high-volume medical device production. The two-component kit format simplifies dispensing and mixing, reducing setup complexity in automated systems. Products have been validated according to ISO 10993 biocompatibility standards, confirming safety for various sterilization methods including gamma, steam, and ethylene oxide treatments. This comprehensive performance profile positions the high heat silicone rubber as a comprehensive solution for next-generation medical device development, enabling manufacturers to produce safer, more reliable complex devices while maintaining production efficiency.
