NuSil Technology's unrestricted materials may be considered for long-term implant applications (greater than 29 days).

High consistency rubber, or HCR, consists of high molecular weight polymer combined with silica to produce a material that can be molded, extruded, or calendared into a useful end product. An HCR has the consistency of clay and is primarily formulated in a one or two part system (peroxide and platinum catalysts, respectively).

Most platinum cure high consistency rubbers are two component systems with an easy-to-work-with 1:1 mix ratio.
