Silbione BIOMEDICAL LIQUID SILICONE RUBBERS (LSRs) are two-component platinum-catalyzed silicone elastomers designed for liquid injection molding medical parts, including selected long-term implant (30 days or more) applications.
Available in a full range of hardnesses from 01 to 70 durometer – Shore A, Elkem Silicones' Silbione BIOMEDICAL LSRs offer the distinctive advantages of easy processing and easy release combined with high performance physical properties.
Silbione BIOMEDICAL LSRs are supplied as kit-matched products. Parts A and B components are designed to be mixed in equal parts using standard liquid injection molding processing equipment and techniques. Airless mixing, metering and dispensing equipment are recommended.
Cure is initiated once the two-part A and part B components are mixed and can be accelerated by heating the mixed elastomer. Cure is dependent upon molding temperature and part size.
Special care must be taken to assure clean molds and a clean work area with no organic rubbers used on the same processing equipment.
Caution: Traces of foreign materials can poison the catalyst and inhibit the cure. All metering and mixing equipment should be thoroughly cleaned. Polymer systems, which contain traces of amines, sulfur, nitrogen oxide, organotin compounds and carbon monoxide can interfere with the cure of this product and should be avoided.
Note: Kit matching, accurate measuring and complete mixing are essential factors in obtaining consistent results.
