Melt Flow Measurement System (OP5)
The OCS Melt Flow Measurement System (OP5) allows the measurement of the Melt Index (MI) of polymer
powder or pellet samples. The OP5 MFR measurement process is carried out by means of exact control
of the melt flow in combination with a highly precise OCS-developed melt-pressure measurement technique.
This method typically achieves a reproducibility of +/− 1%. The fast sampling reduces the delay time
between laboratory and production considerably.
Testable Raw Materials: Pellets and Powder
