The amount of polymer that passes through an orifice in the majority of the melt in 10 minutes and at a specified temperature MFI or the melt flow index of that polymer is called, this sign is actually to show the fluidity of the polymer as a measure of the ability to be extruded, generally with the increase of the melt flow index MFI Molecular weight, tensile strength, tear resistance, softening temperature and toughness, the chemical resistance of the polymer decreases. This index has the opposite relationship with the viscosity. MFI decreases. This feature is used to personalize the grade of petrochemical base polymers and what process and shaping method this polymer is suitable for. For example, high MFI grades are used for the injection process and low MFI grades are used for extrusion. The increase in temperature during the process causes the destruction of the polymer chain, and as a result, more melt is released in a certain time and increases the melt flow index. MFI If the temperature rises more than normal, the chains of the polymer matrix may stick to each other and a phenomenon called crosslinking will occur, which will reduce MFI Therefore, the presence time of the material in the extruder is increased MFI Output materials and so on MFI Materials affect the presence of materials in the extruder and, as a result, the temperature. Other factors such as changing the cutting speed, cooling conditions, and any factor that affects the rheological properties of the polymer cause this parameter to change. In the standard case, the MFI of the product changes. It should not be more than 25% of raw materials. In some situations, increasing the MFI has a vital role in the production and formation process of intermediate and final products. It is based on polypropylene. It should be noted that the increase in the percentage of consumption causes an exponential increase in the amount of this index.

Considering the production problems in the process of textile products, especially the production of Mellat Ballon and Spand Band due to the low melt flow index (MFI) of polypropylene materials of domestic petrochemicals, which is very important these days due to the completion of the production process of these fabrics. Products such as masks, hospital sheets and clothes are impervious to the Covid-19 virus Armen Polymer Company has been presenting its products in this field since 2009 in two grade compound and masterbatch to the biggest manufacturers of this industry including Behpod Yazd Company and has been able to be the first company after interaction and cooperation with the RD centers of the companies involved in designing the formulation of this The product has been a step forward for many years to raise the melt flow index (MFI). To have a significant role in the production industry of Mellat balloon and sponge band as well as recycled polypropylene of the country.
Use this product as an additive with one to five percent by weight after specifying the polypropylene raw materials according to production conditions and machines.
