-The melt flow index test machine(MVR) is a laboratory instrument used to measure the flow properties of a polymer melt. This test is important for determining the viscosity and flow behavior of a polymer material, which can affect its processing and performance in various applications.

-The melt flow index test is commonly used in the plastics industry to compare the flow properties of different polymer materials and to ensure consistency in manufacturing processes. It can also be used to predict the processing behavior of a polymer material and to troubleshoot any issues that may arise during production.

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
