Momentive Performance Materials (Booth 2427) is demonstrating its silicone elastomers for long-term implants at MD&M West. Momentive's ReliaSil UV product line combines the benefits of the ambient cure found in an RTV with the robust physical properties of a high-consistency silicone elastomer, redefining what is possible by offering new capability to proven technologies that will enable the next generation of long-term implants.
ReliaSil UV HCR is a platinum (Pt) cure silicone elastomer. Pt cure systems are also referred to as addition cure as the polymer matrix is formed through an addition reaction that avoids the formation of byproducts, making them preferred in applications where cleanliness and purity are required.
The elastomer ensures suitability for high purity applications with manufacturing operations that are located in a clean room environment. Additionally, each batch is tested for cytotoxicity and heavy metals at an outside laboratory to document the material purity and suitability for the demanding requirements of LTI applications.
ReliaSil UV HCR optimizes the addition-cure reaction with the incorporation of a UV-sensitive inhibitor that replaces the standard heat- sensitive inhibitor. The result is a new generation of silicone elastomers that have revolutionized what is possible in the long-term market, specifically in applications with temperature limitations due to sensitive components or processing controls.
