Detailed Information of the Melt Flow Index Tester

A. Product introduction

It is used to determine the MFR/MVR value of the melt flow rate through the standard die every 10 minutes when various plastics and gums pass through a certain temperature and load in a viscous flow state. It is suitble for melting high temperature polycarbonate, polysulfoxide, fluorine plastics, nylon and other engineering plastics. Also, it is appropriate for the polyformaldehyde, polystrene, polypropylene, ABS resin polyformaldehyde, polycarbonate resin and other low temperature plastic melting test. The machine is widely used in plastic production, plastic products, petrochemical and other industries as well as related universities, scientific research units and commodity inspection departments.

B. Test standards

·B-T3682-2018 Determination of melt flow rate and melt volume flow rate for thermoplastics

·ISO1133: 1997 Determination of melt mass flow rate MFR and melt volume flow rate MVR for thermoplastics

·ASTM D1238 Standard test method for determination of flow rate of thermoplastics melt by extruded plastimeters

C. Features

·Double temperature control system, and more precise of the temperature control accuracy and higher heating efficiency.

·Double imported sensors, more accurate of the upper and lower temperature gradients, independentl used, and improved service life.

·The barrel is made of imported Hastelloy alloynitriding, which is resistant to humic acid, hydrochloric acid and other corrosive materials, and the die is made of carbon tungsten steel.
