Silbione HCRA 4200 Series (HCRs) are two-component platinum-catalyzed silicone elastomers designed for fabricating tubing and medical device parts utilizing extrusion and compression molding processes. This material should be considered for applications requiring less than 30-day implantation in the human body.
The Silbione HCRA 4200 Series products are supplied as kit-matched products. Parts A and B components are designed to be mixed with standard milling processing equipment and techniques.
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 temperature and part size.
Special care must be taken to assure clean molds/dies 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.
