RTP Co. (Winona, MN), a supplier of specialty thermoplastic compounds, has entered into an exclusive sales and manufacturing agreement with Biosafe Inc. (Pittsburgh) to use its silane-based antimicrobial technology in RTP's line of antimicrobial products. The silane-based concentrate can be used as an additive in compounds for a variety of extrusion and injection molding processes.
The technology is faster acting than silver-based additives in rendering plastics antimicrobial and does not cause discoloration, according to Jean Sirois, general manager of RTP. “The active ingredient in these antimicrobial masterbatches only needs to be at a 0.25–0.5% loading in the final product to be effective, making it much more efficient than traditional antimicrobials such as silver or triclosan,” she says. “Unlike silver, silane-based antimicrobials improve color and do not compromise optical properties when used with high-clarity resins.”

Constructed with a diameter of 125 µm, a fiber-optic pressure sensor is the smallest of its kind, according to its manufacturer, Fiso Technologies Inc. The FOP-F125 sensor was developed to extend the reach of pressure-monitoring systems without sacrificing accuracy. Its small profile enables the sensor to be directly mounted at the tip of a fiber-optic cable, thus allowing the sensor to be positioned inside of the body at the exact point of measurement—potentially yielding a more accurate model than traditional pressure-monitoring systems. In addition, the sensor could be embedded in next-generation devices capable of accessing previously unreachable areas of the body.
