Melt Flow Index Tester – Reliable Testing for Thermoplastic Performance | Pacorr.com
-
In the plastic and polymer industry, ensuring the consistent quality of raw materials is essential to delivering high-performance end products. One of the most trusted tools for evaluating the flow behavior of thermoplastics is the Melt Flow Index Tester (MFI Tester). At Pacorr Testing Instruments, we provide advanced and user-friendly MFI testers that help manufacturers maintain quality standards and streamline production.
A Melt Flow Index Tester measures the rate at which a thermoplastic material flows when melted under controlled conditions. This value, called the Melt Flow Index (MFI) or Melt Flow Rate (MFR), is expressed in grams per 10 minutes and indicates the viscosity of the material in its molten state.
The test involves placing a sample of plastic in a heated chamber. A specific weight is applied, forcing the molten plastic through a die. The amount of material that exits the die within a 10-minute window is measured to determine its flow characteristics.
