RTP Company Introduces New High-Flow Conductive Compounds
WINONA, MN, USA - October 15, 2004 - RTF Company has developed new high-flow conductive polypropylene (PP) compounds for thin-wall injection molding, which has become increasingly important for producing complex medical, electronic, and biotechnological devices.
Thin-wall parts have a restrictive flow path leading to narrower processing windows, and the need for specialty thermoplastic materials. When existing materials cannot consistently fill thin-walls or difficult geometries, the new high-flow, conductive PP offers a viable solution without the need to modify tooling or part design. The easy-to-mold, conductive PP materials achieve typical melt flows of 20 grams/10 minutes (2160 grams at 230° C), which compare favorably to existing conductive PP materials (melt flows ranging from 1 to 3).
The materials have been specially designed to minimize warpage and retain their robust physical properties with a notched IZOD impact strength of 2.5 ft-lbs/inch (133 J/m) and a "no break" unnotched IZOD impact strength. These tough, highly conductive compounds offer a surface resistivity of 104 ohms/square (maximum) and volume resistivity of less than 25 ohm-cm. Applications include containers, totes, bins, pipette tips, and explosives handling products.
RTP Company, headquartered in Winona, Minnesota, is a global leader in specialty compounding. The company has six manufacturing plants on three continents, plus sales representatives throughout North America, Europe, and Asia/Pacific. RTP Company's engineers develop customized thermoplastic compounds in over 60 different engineering resin systems for applications requiring color, conductive, flame retardant, high temperature, structural, thermoplastic elastomer, and wear resistant properties.
