Product Description

Melt flow Index-

The Melt flow Index of thermoplastic materials can be defined as the rate of flow (in grams/ minutes) of exudates of molten resins through a jet of a specific length and diameter. The test is carried out under specified conditions of temperature, load and piston position in a cylindrical cavity which is inside a heated metallic tube barrel. The Presto Melt Flow Index Tester provides all standard conditions of temperature accurately and the load is strictly as per the ASTM standards.

The Presto Melt Flow Index tester is equipped with a Micro processor based PID Temperature controller which has a  temperature range from ambient to 400°C. It has resolution of 0.1°C and an accuracy of about ± 0.1°C. The instrument is equipped with a digital pre-settable timer with a range of up to 59 minutes; 59 seconds and buzzer output. The provision of automatic sample cutting ensures accuracy as well as easy operation.
