The molten flow properties, is a vital segment of research studies when we are manufacturing polymer product. The melt low index of polymers state many features and behaviour aspect of the particular test polymer substance. Therefore, testing the features via calculating its Melt flow index or MFI is an important step.
The test process requires a standardized Melt Flow Index Tester to conduct the steps. The testing equipment used for the procedure must be standardized and precise in evaluating the MFI value. It may also support the user to evaluate the Melt flow rate (MFR) and Melt volume flow rate (MVR).
The test equipment heat up the polymer granules till its converts into flowing liquid. This flowing polymer comes out of the machine and is cut at a particular length and weighed separately. The value you get is the MFI data of that polymer. The tester is helpful for checking the flowing properties of liquid plastic material. It is produced under different Test Standards ASTM D 1238-1992, IS 2267-1972, IS 2530-1963, IS 10810-1984. Microprocessor program based PID controller. Automated test specimen cutting for zero interference of human.
Digital based Pre-set Timer for accurate read-out and repeatability. Steel barrel for uniform and steady warming of test chamber. Molten Flow Index is characterized as the flow rate of extrude of the polymer material through a particular length and width under specified states of temperature, load and cylinder position inside a heated metallic barrel. Melt Flow Index of thermoplastic material is communicated as grams per 10 min of extrude of liquid polymer that course through the tube shaped barrel.
