Melt flow index tester: what is the melt index MFI of plastics
Plastic products are widely used in life and production. Different instruments are needed to test plastics. Melt Flow Index Tester MFI is one of the test standards of plastics. So what kind of standard is it? We will introduce to you: what is the plastic Melt Flow Index Tester MFI?
Melt flow index (MFI) is the flow value of plastic materials during processing. MFI is one of the important indexes of mechanical properties of plastic materials. Testing the characteristics of plastic raw materials MFI refers to testing their processing fluidity characteristics.
The Melt Flow Index Tester is used to measure the melt mass flow rate MFR or melt volume flow rate MVR of various plastics and resin polymers in viscous flow state. It is suitable for engineering plastics such as polycarbonate, polysulfone and nylon with high melting temperature.
Generally, there are two test methods for the melt index of Plastics: mass method test and volume method test. The Melt Flow Index Tester melt index is tested according to astm-d1238 and GB / t3682 1-2018.
