Pacorr testing instruments have expertise in designing the ultramodern polymer processing lab testing equipment that is automatic melt flow index tester-computerized. We globally supply this lab test equipment which strictly follows the international industry protocols that are ASTM 1238 and ISO 1133.
INTRODUCTION TO MELT FLOW INDEX RATE
Melt flow index (MFI) or Melt Flow Rate (MFR) is the process of determining the flowability of the molten polymer in a particular time frame. MFI is defined as the granules taken in grams into the heating barrel then the temperature and pressure applied to molten the polymer within 10 minutes so that it can flow easily for various applicability like injection molding, blow molding, extrusion etc.
HOW TO MEASURE MELT FLOW INDEX
Melt flow index is the measurement ease of flow of thermoplastics. ISO standard 1133 measurement procedure is followed by Pacorr Melt flow Index tester which are as follows:
- A small amount of granules is taken into the heating barrel approximately 4 to 5 grams as a sample to test. The temperature is maintained as per the polymer chosen to test up to 400 degree celsius.
- To avoid air pockets while testing the sample is packed properly inside the barrel.
- After preheating standardized weight is kept on the piston.
- The piston applies pressure on the molten polymer which further leads to flow through the capillary die.
- After a time period of 10 minutes the flow is auto cut and weight is measured. The MFI expressed unit is gm/10 minutes.
MFI ROLE IN QUALITY ASSURANCE
The evaluation of MFI helps in assessing the viscosity, flow characteristics, sample preparation, process applicability and molecular weight distribution. The various properties of polymers can be enhanced by MFI testers, mechanical strength, processability, durability, deformation resilience, thermal stability, melt strength, environment resistant and alleviating shrinkage.
MFI value impacts in enhancing the quality, durability and reliability of molding polymers.
ADVANTAGES OF MEASURING MFI
The evaluation of MFI value will lead to following advantages:
- Evaluation of ease of flow
- Assessing the polymer behavior before molding and extrusion
- Prevent lots rejection
- Quality assurance
- Grading granules
- Assessing production control
- Appropriate material selection
- Ensuring accuracy in molding processes
This blog signifies that by determining accurate and precise evaluation of melt flow index will lead to optimized process condition and quality assurance. The above mentioned factors will maintain reliable and consistent results which leads to high rise in productivity.
The MFI provides valuable insight for the manufacturers of polymers and plastic industries. Pacorr meticulously worked on how to strengthen the vast polymer based manufacturer and researchers. Pacorr has manufactured an ultra modern polymer lab testing equipment that is Melt Flow Index Tester at a very affordable price.
