	6MPCA Advanced Melt Flow Tester with Techni-Test software The Melt Flow Index is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer in grams flowing in 10 minutes through a capillary of specific diameter and length by pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures as specified in the ASTM D1238 and ISO 1133 Test Standards The Melt flow rate is an indirect measure of molecular weight, a high melt flow rate corresponding to a low molecular weight. At the same time, melt flow rate is a measure of the ability of the material's melt to flow under pressure. Melt Flow rate is inversely proportional to the viscosity of the melt at the conditions of the test, though it should be borne in mind that the viscosity for any such material depends on the applied force. Ratios between two melt flow rate values for one material at different gravimetric weights are often used as a measure for the broadness of the molecular weight distribution. Melt flow rate is commonly used for polyolefin’s, polyethylene being measured at 190°C and polypropylene at 230°C. The end user should choose a material with a melt index so high that he can easily form the polymer from its molten state into the article intended, but on the other hand so low that the mechanical strength of the final article will be sufficient for its use. Although not a fundamental property of the material, the MFI is one of the most widely used parameters for the quality control of polymers Model 6MPCA - Advanced Melt Flow Indexer. This Melt Flow Indexer measures the Melt-Flow Rate (MFR) and Melt-Volumetric Rate (MVR) of the polymer under specified conditions of temperature and load. The MFI results are expressed as g/10min and the MVR is expressed as cubic cm/10min.The multi slicing features provides 20 test results over the selected travel distance, density at test temperature, viscosity and shear stress are also given. Statistical analysis includes averages and standard deviation.

	Apparent Bulk Density Apparent Bulk Density. Ray-Ran offer 4 models which are used are used to measure apparent density, bulk factor, and where applicable, the pourability of plastic materials in forms such as moulding powders. There are three methods according to the ASTM D 1895 standard and one to the ISO R60 standard that are applicable to various forms of these materials that are commonly encountered - from powders and granules to large flakes and cut fibers. The Apparent Bulk Density measurement provides a very good indication of the handling, packing and the space requirements.

	Digital Readout Density Gradient Column Digital Readout Density Column. - The gradient column method accurately measures the density of small solid materials, in various forms, Pellets, Granules, film etc..and conforms to the ASTM D1505 & ISO 1183 Method D standards. The density is formed by mixing two fluids having different densities. The resulting solution has a density which when introduced into the column increases uniformly from top to bottom. Ray-Ran's new advancement means that density measurements can be made more quickly and more accurately. The height of the calibrated marker floats or samples introduced into the density gradient are measured using a trammel guided "sight" connected to a positional encoder relaying the height position to a microprocessor so that the density can be obtained without the need for graphs etc. This also means that the Gradient can be calibrated & checked at any time.

	Melt Flow Weights To attain the loads specified by the Test Standards for different polymers & materials, Ray-Ran uses a modular weight system for its Melt Flow Test Weights. Note that the piston used with the 5 Series Advanced Melt Flow Systems is fitted with a disc which moves the measuring arm down as the piston descends. the weight of the piston and disc is 0.325kg which is the smallest weight used for MFI testing and any additional weights used take this into account.
	Moisture Analyser The Ray-Ran MB series of Moisture Analysers are a thermogravimetric apparatus based on the halogen radiator technology. This instrument can be used to measure the moisture content is a wide variety of materials. The MB45 is equipped with a halogen radiator which is more responsive to the heating & cooling requirements than traditional IR heaters. To ensure even heat distribution, a gold plated reflective shield lines the inside lid of the analyser.
