Dow Corning® C6-350LH

High Consistency Rubber with platinum cure Raw materials with enhanced physical properties for healthcare industry fabrication

APPLICATIONS
DOW Corning Class VI Elastomer C6-350LH is a platinum-catalyzed heat-cured silicone High Consistency Rubber for part fabrication, extrusion and medical devices, including those intended for implantation in humans for up to 29 days.

This material exhibits enhanced physical properties and may be particularly beneficial for fabricating devices and products where high resilience (low hysteresis loss) is important.

DESCRIPTION
DOW CORNING C6-350LH Elastomer, Parts A & B is a two-part platinum-catalyzed silicone elastomer. It is supplied as a two-part kit (Part A & B), equal portions of which must be thoroughly blended together prior to use. The elastomer is thermally cured via an addition-cure (platinum-catalyzed) reaction. When blended and cured as indicated, the resulting elastomer consists of crosslinked dimethyl and methyl-vinyl siloxane copolymers and reinforcing silica.

DOW CORNING C6-350LH Elastomer differs from our conventional high consistency rubber (HCR) products in that it exhibits enhanced physical properties. In particular, it exhibits lower hysteresis losses (more resiliency) compared to other platinum-catalyzed HCRs, and a reduction in crack growth propagation.

The elastomer can normally be used without any post-cure, although if necessary, this may be employed to stabilize final properties. Furthermore, the elastomer is heat stable up to 204°C (399°F), can be autoclaved, and exhibits high gas permeability compared with most thermoset elastomers and thermoplastics.
