SILBIONE® BIOMEDICAL HCRs are supplied as kit-matched products. Parts A and B components are designed to be mixed with standard mill, extruder, or injection molding processing equipment and techniques.


Cure is initiated once the two-part part A and part B components are mixed and can be accelerated by heating the mixed elastomer. Cure is dependent upon temperature and part or profile size.

Special care must be taken to assure clean mixers, mills, dies, 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.

SILBIONE BIO HCRA M530 A+B may be stored for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


SILBIONE® BIOMEDICAL HIGH CONSISTENCY RUBBERS (HCRs) are two-component platinum-catalyzed silicone elastomers designed for extruding or injection molding medical parts, including long-term implant (30 days or more) applications.

Available in a full range of hardnesses from 20 to 80 durometer – Shore A, Elkem Silicones' SILBIONE® BIOMEDICAL HCRs offer the distinctive advantages of easy processing and easy release combined with high performance physical properties.
