What is a plastic MFR tester?

- Apr 23, 2020-

Melt flow rate (hundred MFR) instrument: It is a high temperature heating furnace to make the measured object reach the molten state under the specified temperature conditions. The test object in this molten state is subjected to an extrusion test through a small hole with a fixed diameter under a prescribed weight load gravity. In the research of plastic production and scientific research units of industrial enterprises, "melt (mass) flow rate" is often used to express the physical properties of polymer materials such as fluidity and viscosity in the melted state. Melt flow rate refers to the average mass of each sample of the extrusion publication converted to 10 minutes of extrusion. The melt (mass) flow rate is expressed by the weight MFR, the unit is: grams / 10 minutes (ie g / min).
