Melt Flow Index (MFI)
|
Melt flow index (MFI) is the output flow rate in grams that occurs in 10 minutes period through a standard die of 2.0955 mm diameter and 8.000 mm in length while a fixed pressure is applied to a 190°C melt via a piston. Blow molding and extrusion processes tend to use resins with lower melt flow index values. Injection molding typically utilizes higher MFI polymers. Products & Services
Linear power supplies accept AC inputs and provide one or more DC outputs for a wide variety of computer and industrial applications. They use an active element (normally a power transistor) operating in its linear region to generate a desired voltage.
