WJ-400B Melt Flow Rate Tester

The melt flow rate meter is an instrument used to measure the mass flow rate (MFR; unit: g/10min) of thermoplastic melts, in accordance with GB/T3682-2018, ASTM D1238 standards, and similar standards such as JB/T5456 and ISO1133. Widely used for determining the melt index value of thermoplastic materials.

1、 Compliant with standards

This instrument complies with the requirements of JB/T5456 standard and is applicable to standards such as GB/T3682, ASTM D1238, ISO1133, etc.
