Selected Qualification Data for Dow Corning Class VI Elastomers

1. Elastomer was compounded with 50% 2, 4-dichlorobenzoyl peroxide at 1:100 ratio. Unless otherwise noted, samples were molded 5 minutes at 116°C (240°F) and

post-cured 2 hours at 177°C (350°F). Elastomer samples were autoclaved before all biocompatibility tests.

2. Tests meet ISO 10993-1 requirements for surface devices with limited (<24 hours) or prolonged (1 to 30 days) contact duration.

3. European Pharmacopoeia monograph 3.1.9: Silicone Elastomer for Closures and Tubing. Samples were molded 5 minutes at 116°C (240°F) and post-cured

4 hours at 204°C (400°F). Samples were not sterilized prior to this testing.

Typical Properties

1. Properties (except relative density) obtained from 1.905-mm (0.075-inch) thick ASTM slab equilibrated a minimum of 3 hours at ambient conditions.

2. Corporate test method (CTM) procedures correspond to standard ASTM tests in most instances. Copies of CTMs are available upon request.

3. 1.0 parts PERKADOX PD-50S compounded with 100 parts base, molded 5 minutes at 115°C (240°F).

4. 0.5 parts DI-CUP R compounded with 100 parts base, molded 10 minutes at 160°C (320°F).
