products & literature Instron, Norwood, Mass., released the Specimen Self-Heating Control (SSHC) add-on to its WaveMatrix software package for dynamic and fatigue testing of polymers and composites. The add-on uses the difference between the specimen's continuously recorded temperature and a pre-specified temperature target to maximize the testing frequency in a closed loop. For lower loading, where very large numbers of cyclesto-failure are expected, the system can run at a significantly higher frequency, which greatly reduces the test duration. www.instron.com. Fluke Corp., Everett, Wash., introduced the Fluke VT04 visual IR thermometer, a troubleshooting tool with a built-in digital camera and thermal heat map overlay to help bridge the gap between traditional IR thermometers and infrared cameras. It is well suited for frontline troubleshooting for electrical systems, industrial maintenance, HVAC/R, and in automotive applications. Built-in intelligence allows issues to be detected without specific operator training and a time-lapse image capture can be set to capture images in 30-second to one-hour intervals. Images may be displayed and saved in full digital, full infrared, or in three blended modes. www.fluke.com. Innegra Technologies, Greenville, S.C., launched its Innegra H product line, a series of hybrid yarns for use in reinforcement and composite manufacturing processes. Benefits range from creating lighter weight and more impact-resistant sporting equipment to decreasing the weight of automotive body parts while reducing the danger of a crash-related catastrophic failure. The line consists of high-performance olefin yarn comingled with other high-performance composite fibers, including aramid, basalt, carbon, and glass to increase durability and avoid the shattering effect of current lightweight composites. Hybridization is done at the filament level, allowing for a more homogeneous final part. www.innegratech.com. Malvern Instruments, UK, published an article detailing the use of laser diffraction particle size analysis for powder metallurgy applications. The article presents new data on how laboratory and inline laser diffraction provide the comprehensive particle size and size distribution data required to support metal powder product and manufacturing process development. The article details the combined use of Malvern's Mastersizer 3000 and Insitec laser diffraction particle size analyzers for metal powder process development. www.malvern.com/measuring-metal-powders. To produce low-frequency active sonar, Morgan Advanced Materials, UK, manufactures a range of stave components, assembled together to create large ceramic rings and used as underwater projector transducers. To combat size restrictions, electrodes are positioned between each ceramic segment, with segments then poled around the circumference. Ceramic stave components are available in a combination of lengths and widths from 10 to 165 mm, with thicknesses from 10 to 40 mm. Larger or smaller staves can also be created. www.morganadvancedmaterials.com. RTP Co., Winona, Minn., introduced a new series of flame-retardant products for use in applications installed in air-handling spaces to meet the UL 2043 standard for heat and smoke release. Compounds are available in polyolefins, polyamides (nylons), and other engineering resin systems and are supported by RTP's global facilities that provide technical support from design through finished part production. Compounds are tailored for injection mold84 ADVANCED MATERIALS & PROCESSES • NOVEMBER-DECEMBER 2013 ing or extrusion processing and also may be used as a drop-in substitute for existing plastic applications to seamlessly transition them to a UL 2043-compliant solution. www.rtpcompany.com. Metallized Carbon Corp., Ossining, N.Y., introduced mechanical seal primary rings for sealing refrigerants and other low viscosity liquids. Metcar Grade M-444 offers self-polishing characteristics and dimensional stability. It is the self-polishing characteristic of M-444, antimony impregnated, carbon-graphite material and the high dimensional stability of both solid silicon carbide and antimony impregnated carbon-graphite that enables these two materials to run in the required close proximity. www.metcar.com. Shimadzu Scientific Instruments, Columbia, Md., introduced a new HMV-G Series of Micro Vickers hardness testers that provide an operator-friendly, cost-effective solution with automatic length measurement. Equipped with a CCD camera for automatic length measurement, the testers provide simple, secure analysis with minimal risk of human error. Their new G-frame design expands the workspace, improving operability while permitting effective measurement of long and large test samples. With the routine inspection graphs function, data can also be viewed in chronological order, so it can be used effectively for ISO17025 and ISO16949 certification. www.ssi.shimadzu.com. Most cutting-off applications can be performed by a new generation of medium and large diameter reinforced cut-off wheels called TOROS by Saint-Gobain Abrasives under its NORTON brand, Carol Stream, Ill. Wheels are available in diameters to 1.8 m and are intended for automatic or semi-automatic cutting on static machines, not freehand use. Versions are available for cutting most metals, from copper alloys to stainless steel and titanium slab, billet, bar, and tube, of large or small cross section, at any temperature to 1000°C. Eight categories provide different cutting characteristics, based on various blends of alumina, zirconia oxide, and silicon carbide abrasive grains. www.sgabrasives.com. Dow Corning Corp., Midland, Mich., offers a new high-consistency silicone rubber with superior fatigue resistance in extreme heat and cold. Silastic HCM 60-1225-GRAY silicone rubber exhibits very high extensional and flexural fatigue life, high tensile and tear strengths, high elongation, good heat-aging stability with low compression set, and stable physical properties for reliable performance from -40° to 200°C (-40° to 392°F). It offers process stability, fast cure times at elevated temperatures, excellent mold release, and higher throughput without post-curing required. www.dowcorning.com. Bose ElectroForce Systems Group, Eden Prairie, Minn., introduced the 3200 Series III family of test instruments, for improved accuracy, performance, and ease-of-use for materials testing. The advanced electrodynamic test system delivers fatigue testing response up to 300 Hz and DMA testing to 200 Hz. Equipped with a new proprietary acceleration compensation algorithm, the system can correct acceleration-induced force errors, ensuring higher-accuracy force measurement while providing improved control at higher frequencies. The algorithm is integrated with a displacement measurement system that provides resolution of 1 nm and accuracies in the range of microns. www.bose-electroforce.com.
