M0004 Melt Index Apparatus

Melt FlowIndex (MI), the full name of Melt Flow Index, or Melt Flow Index, is a numerical value indicating the fluidity of plastic materials during processing. It is formulated by the American Standards Association according to the method used by DuPont to identify the characteristics of plastics.

Melt Indexer
Model: M0004
Melt FlowIndex (MI), full name melt flow index,
Or melt flow index, which is a way to indicate the flow of plastic materials during processing
The numerical value of sex. It is the American Measurement Standards Association according to DuPont
Developed by the usual methods of identifying the characteristics of plastics.
The specific operation process of the test is: the polymer (plastic) raw material to be tested
Put it in a small groove, the end of the groove is connected with a thin tube, the diameter of the thin tube is 2.095mm,
The tube length is 8mm. After heating to a certain temperature (usually 190 degrees), the raw materials
The upper end uses a piston to apply a certain weight to squeeze downwards to measure the raw material
The weight extruded in 10 minutes is the flow index of the plastic.
The commonly used method of expression is: MI25g/10min, which means in 10 minutes
The plastic is extruded 25 grams. Generally, the MI value of commonly used plastics is approximately between
Between 1-25. The larger the MI, the smaller the viscosity of the plastic material and the smaller the molecule
The smaller the weight, on the contrary, the greater the viscosity of the plastic and the greater the molecular weight.
