New extensometer for accurate plastics testing launched

Lloyd Instruments : 27 July, 2006  (New Product)
Chinaplas 2006 will provide the first opportunity in the People’s Republic of China to see Lloyd Instruments’ versatile new EXPlus extensometer for the accurate extension measurement of materials such as semi-rigid plastics, elastomers and rubbers. The EX800Plus extensometer will be fitted to an LRXPlus low force single column materials testing machine. Also on show will be the LFPlus single column test instrument, and the MFI-10 melt flow indexer and recently upgraded HDT/Vicat measurement instrument from the Davenport range of polymer test equipment.


The EX800Plus extensometer will be fitted to an LRXPlus low force single column materials testing machine. Also on show will be the LFPlus single column test instrument, and the MFI-10 melt flow indexer and recently upgraded HDT/Vicat measurement instrument from the Davenport range of polymer test equipment. Available in two travel lengths, 250 mm and 800 mm, the EXPlus extensometers can be fitted to any of the company’s EZ and Plus Series of materials testing machines for testing up to 150 kN. In addition to increased travel over previous models and capable of accepting samples up to 25 mm thick, these high accuracy new extensometers can be mounted rigidly in a variety of ways, providing enormous adaptability for accommodating samples and fitting interchangeable grips. They are used to test high elongation materials to yield and break in full accordance with ISO 9513: 2002. The LFPlus and LRXPlus machines provide versatile materials testing capabilities for tensile, compression, flexural and friction testing applications at forces up to 1 kN, and 5 kN respectively. All of the instruments on show can be operated under computer control with the company’s NEXYGEN MT control and analysis software. NEXYGEN software immediately recognises the ‘plug and play’ extensometer and in addition features a vast library of international standard tests for many different applications. The Davenport HDT/VICATPlus instrument is used to test plastic material for Heat Distortion Temperature and VICAT, a measure of the temperature at which plastic starts to soften rapidly. With six independent test stations, the instrument now features an improved design to further enhance protection for operators from possible exposure to the heating oil used in the system. The Davenport MFI-10 melt flow indexer is an intelligent modular system, which allows fully automatic measurement of the melt flow rate of a polymer. It can be used both by resin manufacturers and processors such as extruders and injection moulders to measure the melt flow rate and melt volume rate of thermoplastics before use in the manufacturing process. To complement its range of products for the plastics industry, Lloyd Instruments also manufactures melt viscometers (for intrinsic and melt viscosity testing of PET), density gradient columns and falling dart impact testing equipment for plastic film.
