ReliaSil™ UV Cure Silicone Elastomers for Long-Term lmplants

Temperature Sensitive Additives: Reliasil UV HCR offers a distinct advantage when considering formulations with temperature-sensitive components such as active pharmaceutical ingredients (APls). 

ReliaSil UV HCR provides a unique combination of low-temperature, UV cure with robust physical properties in a command-cure package that is activated by UV light (365 nm). 

These distinctive properties enable applications where the direct addition of the API to the device will allow for enhanced performance. Applications typically involve a requirement for a precise loading of the API, or a secondary process when solvent impregnating is undesirable or not possible.

Temperature Sensitive Components: Implants that incorporate temperature-sensitive components are often limited in material choices that offer low-temperature cure and strong physical properties. Batteries are one of the more sensitive components, which typically have an upper temperature range of 80 °C. 

RTVs meet the necessary curing temperatures, but lack the robust properties (e.g., tear, tensile, elongation) of a silicone elastomer. 

Medical devices designed with ReliaSil UV HCR harness the robust physical properties of a silicone elastomer while curing well under the upper temperature limits of the battery, optimizing battery life and enabling designers to create new, more robust solutions.
