WebFlow Polymers provides a complete line of single and multiple ingredient value added dispersions to improve processing and insure safe handling of rubber and plastic additives. We have the technology to change the physical form and/or packaging of raw materials that are difficult for compounders to use in their original forms. WebThe Melt Flow Index (MFI) 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 ten minutes through a capillary of a specific diameter and …

WebApr 14, 2024 · While both ASTM D1238 and ISO 1133 are used to determine the MFI of polymers, there are some key differences between the two standards. One significant difference is the die diameter. ASTM D1238 specifies a die diameter of 2.095 mm, whereas ISO 1133 provides options for die diameters of 2.095 mm, 1.18 mm, and 0.64 mm.
