Designing materials for long‑term implants requires a balance of biocompatibility, mechanical strength, and precise manufacturing control. Silicone elastomers have a long history of success in implantable medical applications due to their purity, stability, and hypoallergenic nature. The ReliaSil™ silicone elastomers are developed for this reason. The first ReliaSil product is based on UV Cure which combines low‑temperature UV curing with the physical performance of a high‑consistency silicone elastomer, enabling advanced solutions for implantable devices, electronics encapsulation, API‑containing components, and battery‑integrated systems where thermal exposure must be minimized.
Silicone elastomers offer proven biocompatibility, chemical stability, and hypoallergenic properties, making them well‑suited for long‑term contact with the human body in implantable medical devices.
UV command cure allows silicone elastomers to remain uncured until exposed to UV light (365 nm), giving manufacturers precise control over processing while enabling low‑temperature curing for sensitive components.
Low‑temperature curing helps protect temperature‑sensitive components such as batteries, electronics, and APIs, reducing thermal stress during manufacturing while maintaining robust mechanical performance.
Yes. UV cure silicone elastomers can support direct API incorporation, enabling precise loading and uniform distribution without exposing sensitive ingredients to elevated cure temperatures. Certain technical variables such as platinum cure inhibition, silicone crosslinking density and API UV absorption need to be considered when selecting the API.
While RTVs offer low‑temperature curing, they often lack the mechanical strength of silicone elastomers. UV cure HCR silicones combine low‑temperature processing with enhanced physical properties such as tear strength and elongation.
Yes. Their low‑temperature cure and robust mechanical properties make them well‑suited for encapsulating implantable electronics and battery‑powered medical devices.
Applications include long‑term implants, combination devices, implantable electronics, wearable medical devices, sensors, and systems requiring precise material control and durability.
