MFR Melt Flow Indexer Comply With ASTM D1238 and ISO 1133
This instrument is the most updated one that has been added many functions.The instrument configuration, equipment life, operation convenience and test accuracy has been greatly improved. Compared with the general domestic instruments,this melt flow tester has the most competitive advantage and cost.
(1).The heating cylinder is made up of 304 stainless steel or alloy, for the reason that in high temperature metal material is easily oxidation rust while the melting flow index tester usually performs long-time work at high temperature(up to 400~500 degrees).
(2).The melting flow index rate instrument is equipped with dual sensor configuration to get precise temperature control and better temperature gradient so that the instrument can work longer.
(3).According to the national standard, function that four minute countdown after feeding is added in the machine.
(4).The RS232 interface is available to be connected to the computer to output data(optional).
(5).The last test conditions can be directly displayed after boot-strap to avoid users resetting test parameters each time ,reducing the workload of the operators.
(6).The maximum temperature can be up to 450~500ºC(optional, special instructions when ordering)
(7). After long time test of strong corrosive plastic such as full fluorine plastic, the accuracy of the instrument is non-destructive.( Because the material is special, please specify it when ordering)In the mainland of China only testing instrument company has this technology so far.
(8).Meeting standards:ISO 1133, ASTM D1238, GB/T3682
The instrument can be used to test the melt flow rate(MFR) figures of all kinds of plastic and resin in the viscous flow state. It is not only suitable for the high melting temperature engineering plastics of polycarbonate, polyarylsulfone , fluorine plastic and nylon but also suitable for some other low temperature plastic products which are made up of polyethylene(PE), polystyrene(PS), polypropylene(PP), ABS resin, polyoxymethylene(POM) and polycarbonate. So it is not only widely used in the plastic production, petroleum and chemical industry but also in the relevant institutions such as scientific research units and the community inspection departments.
The melt flow rate instrument is suitable for measuring the thermoplastic melt mass flow rate following the determination in the standard ”GB/T3682-2000 thermoplastic melt mass and volume flow rate measurement”. The standard is equivalent to the requirement in the ISO 1133:1997 and can meet the ASTM D1238 test.
Considering the beautiful appearance and convenient operation ,the desktop structure of the melt flow rate instrument makes the equipment performance reliably and stably. Besides, the high-precision control instrument using fuzzy PID algorithm for temperature control has the feature of high sampling precision and high speed control.
(1).fast heating speed,minimal overshoot
(2).high precision of constant temperature
(3).A constant temperature can be quickly restored after packing .
(4).Test parameter calibration and correction is convenient.
(5).Manual and automatic cutting test methods are optional.
(6).The instrument is equipped with LCD working platform.
(7).The test results are automatically printed putout equipped with a printer.
