ASTM D1238-98 Thermoplastics materials Melt Flow Index Tester , MVR / MFR Testing Equipment
Download Brief:
ZL-3014B Automatic Melt Flow Rate Meter.pdf
Applications:
Plastic Melt Flow Index Test Instrument MFI of GB/T3682-2000 and ASTM D1238-98.And also ,we design and
manufacture the instrument after we made a reference of similar
standards ,such as JB/T5456 and ISO 1133 .It is used to determine
the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR)
of thermoplastics materials .It adopts auto sampling method and the
cut samples are weighed up by balance when it is used to determine
MFR .When it is used to determine MVR ,it measures the time which
the piston is used to move the specified distance first through the
displacement transducer and auto timer system and calculates MVR
according to the formula later. The final results of the two
methods are all displayed on the machine’s LCD screen and printed
and exported by computer .The instrument has high accuracy on data
measurement with simple operation and stable capability. It is not
only suitable for the tests of engineering plastics with higher
melt temperature ,such as PC ,FI plastics, nylon ,but also for the
plastics with lower melt temperature ,such as PE ,PP ,POM ,PS ,ABS
resin and poly carbonic acid ester ,etc .It has wide range of
applications in some industries ,such as plastic fabrication
,plastic goods ,petrochemical industry ;collage and university and
science and research institute and commodity inspection department
.
