The Hung Ta™ Melt Index Tester is a durable, high quality apparatus for measuring the rate of extrusion of molten thermoplastic materials, such as TPEs, TPRs, PVC, etc., as described in ASTM D1238 “Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer,” specifically condition 190/2.16.
The Melt Index (MI) is the measurement of the rate of extrusion of molten thermoplastic resins through a die of a specified length and diameter under prescribed conditions of temperature, load, and piston position in the barrel over a specific time interval.
The Hung Ta™ Melt Index Tester is also used for preparing specimens according to ASTM D2839 “Standard Practice for Use of a Melt Index Strand for Determining Density of Polyethylene.” for use in ASTM D1505 “Standard Test Method for Density of Plastics by the Density-Gradient Technique.”
