ISO 1133 Melt Flow Index Tester PC PP Melt Index Of Plastics
Digital Melt flow index tester as per method A of ASTM D 1238 with auto cutting facility.
Standard:
GB/T3682-The measurement of the mass flow rate for thermoplastic.
The basic element of the melt indexer is to meet the accuracy requirements and test methods specified in the international standards. The standards include those common in ISO 1133, GB/T3682, JIS K 7210, ASTM D1238 and PVC tests of ASTM D3364, plus provisions in specific standards.
Determination of melt index according to Method A; melt mass flow rate (MFR)
In this method, the extrudate is cut in a specified time and the mass of the cut extrudate is weighed on an analytical balance. The test result is the mass of extrusion per unit time, in g/10 min. The quality of the resulting MFR results is related to the cutting time and the accuracy of the stated mass. If the MFR index is low and a longer cutting time is required, we recommend using manual cutting.
Determination of melt index according to Method B; melt volume flow rate (MVR)
This method requires a melt indexer/extrusion plastometer equipped with a piston displacement sensor. The MVR results are obtained by measuring the volume of the extruded material per unit time in cm3/10 min. Calculated from the displacement of the piston in a certain period of time. The significant advantage of this method is the elimination of mechanical cutting. It has the features of simultaneous recording of piston displacement and test time while achieving high accuracy, even for short measurement times and small piston displacements. Depending on the material, accuracy requirements and MVR results, the same bucket can test up to 40 separate measurements.
Determination of melt index according to Method C
A drum with a height of 8.00 mm and a nozzle with a diameter of 2.095 mm are commonly used. The MFR value measurement is better than the recommended 75 g/10 min in the standard, and the size of a "half height/half caliber" drum is 4.00/1.050 mm. This is specifically designed for ASTM D1238 Method C.
Melt Index Measurement in Method D - ASTM D1238: Multi-Step Measurement
For many polyolefins, different force values are typically used to measure the MVR and flow rate ratio (FRR). When using a simple melt indexer, multiple fillers need to be tested. The melt indexer is equipped with an automatic transformation weight unit that measures the results of individual fillers at different force values.
