Polymer testing instruments is the test method to determine the flow performance of thermoplastics at high temperature instrument, is the formosu instrument company melt index instrument, the instrument implementation of JB/T5456 standard requirements, the latest American microcomputer (single chip microcomputer) control, Chinese operation interface, automatic test results;Used for determination of melt flow rate of polyethylene (PE), polypropylene (PP), polyformaldehyde (POM), polystyrene (PS), ABS plastics and polycarbonate (PC) at high temperature.It has the advantages of simple operation and high control precision.
The e instrument is in compliance with the JB/T5456 standard and is applicable to GB/T3682 and ISO1133.Such as standard,
Working Principle
Melt flow rate meter is a kind of extrusion type plastic meter.It is in the specified temperature conditions, using high temperature heating furnace to test the material to reach the melting state.In this molten state, the test object is extruded through a hole of a certain diameter under the load gravity of the specified weight.In the plastic production of industrial enterprises and research institutions, "melt (mass) flow rate" is often used to express the physical properties of polymer materials such as fluidity and viscosity in the melting state.
