Newly developed selective self-adhesive silicone rubbers can be co-molded with nylons, polycarbonates, and PBT-type polyesters, creating new design opportunities in medical devices and cars. “These materials can eliminate assembly operations for needle-less IV valves,” comments Eric Bishop of Shin-Etsu Silicones. The new materials’ combinations are also replacing gum rubber in automotive applications. Bishop spoke at Molding 2008 in San Francisco. The materials are called selective because they don’t adhere to steel.
NIST's new five-year strategic plan for its Material Measurement Laboratory lists additive manufacturing materials development as one of the main areas it will support by developing measurements, data, techniques, and models.
