Melt Flow Index Tester(MFR) Working Principle
Melt Flow Index Tester (MFR) is to use a high temperature heating furnace to make the measured object reach a molten state under the specified temperature conditions. The test object in this molten state is subjected to the extrusion test through a small hole of a certain diameter under the specified weight load. In the research of plastic production in industrial enterprises and scientific research units, “melt (mass) flow rate” is often used to represent the physical properties such as [...]
