Melt Flow Index Tester is a test equipment used to determine the melt fluidity of plastic materials. It provides an important indicator for evaluating plastic melting performance and processing performance by measuring the melt flow rate of plastic materials at specific temperatures and pressures.
The following are the main contents that Melt Flow Index Tester can measure:
1. Melt Flow Rate (MFR): Melt Flow Index Tester can measure the melt flow rate of plastic materials under specific temperature and pressure conditions. MFR refers to the quality of molten plastic that passes through a standard orifice within a certain period of time, and is one of the important indicators for evaluating plastic melting performance and processing performance.
2. Melt Volume Rate (MVR): Melt Flow Index Tester can also measure the melt volume flow rate of plastic materials. MVR refers to the volume of molten plastic passing through a standard orifice within a certain period of time. Compared with MFR, it more accurately reflects the flow properties of plastic materials.
3. Melt Flow Index (MFI): The melt index is a relative indicator of the melt flow rate, usually in grams/10 minutes (g/10 min). It is an important parameter to measure the melt flow performance of plastic materials under specific temperature and pressure.
4. Melting temperature: Melt Flow Index Tester can determine the melting temperature of plastic materials, that is, the temperature at which the material starts to melt. Melting temperature is an important parameter in the processing and molding of plastic materials and is critical to ensure that plastic materials flow and form the desired shape at the proper temperature.
The measurement results of the Melt Flow Index Tester can be used to evaluate the processability, melt stability, flow properties and melt volume of plastic materials. These parameters are of great significance for the selection of plastic raw materials, the design of plastic products and the control of the production process. Through the test of Melt Flow Index Tester, it can help manufacturers and R&D personnel determine the most suitable plastic materials for specific applications, and optimize the production process to ensure the stability of product quality and performance.
