Hung Ta Melt Index Tester

The Melt Index Tester available from Hung Ta is a quality and durable apparatus, which can be used for calculating the extrusion rate of PVC, TPRs, TPEs and other molten thermoplastic materials, as outlined in ASTM D1238 “Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer”. In addition, the apparatus is utilized for preparing specimens in accordance to ASTM D2839 “Standard Practice for Use of a Melt Index Strand for Determining Density of Polyethylene” for use in ASTM D1505 standard.

The Melt Index refers to the measurement of the extrusion rate of molten thermoplastic resins via a die of a particular diameter and length under approved conditions of load, temperature, and piston position in the barrel over a definite time interval.
