A. Product description:
It is used to determine the MFR value of the melt flow rate through the standard die every 10 minutes when various plastics and gums pass through a certain temperature and load in a viscous flow state. It is suitable for melting high temperature polycarbonate, poly sulfoxide, fluorine plastics, nylon and other engineering plastics. Also, it is appropriate for the poly formaldehyde, polystyrene, polypropylene, ABS resin poly formaldehyde, polycarbonate resin and other low-temperature plastic melting test. The machine is widely use in plastic production, plastic products, petrochemical and other industries and related universities, scientific research units and commodity inspection departments.
B. Test standards:
1. GB-T3682-2018 Determination of melt flow rate and melt volume flow rate for thermoplastics
2. ISO1133: 1997 Determination of melt mass flow rate MFR and melt volume flow rate MVR for thermoplastics
3. ASTM D1238 Standard test method for determination of flow rate of thermoplastics melt by extruded plastimeter
C. Advantage:
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 (RT-450℃).
2. According to the national standard, function that four minute countdown after feeding is added in the machine
3. 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.
4. The maximum temperature can be up to 450~500℃.(optional)
5. Meeting standards:ISO 1133, ASTM D1238, GB/T3682
6. Integrated manual and automatic cutting, cutting time and number can be set
7. Can be equipped with European standard, American standard, British standard and other power plugs
8. Test parameter calibration and correction is convenient
9. Fast heating speed, minimal overshoot
