Purpose: Experimental determination using the MFR and MVR methods to obtain the most uniform material, smooth, without structural defects. Design/methodology/approach: The device used to determine the index MFR and MVR was MFlow extrusion plastometer, Zwick/Roel. The evaluation of obtained samples was carried out using a stereoscopic microscope, Zeiss, and a scanning electron microscope Supra 25, Zeiss. Determination of the chemical composition of materials was carried out by using IR spectrometer with Fourier transformation, SpectroLab. Findings: One of the requirements for quality control of thermoplastics is determination of volume and mass flow rates. To ensure in industry that production is reproducible it’s important to control this index. Practical implications: The purpose of the determination of MFR and MVR is a quick and inexpensive knowledge about the basic properties of thermoplastics processing, which is the flow rate. Knowing the material’s quality which is introduced into the manufacture makes the process parameters selection (injection molding, extrusion) much easier. It also reduces the time and minimizes the cost of the production setup. Originality/value: The MFR and MVR were experimentally determined and they have been confirmed by microscopic research. The research were focused on observing the topography changes depending on temperature.
