ASTM D1238-13

ASTM D1238-13 is a standard that outlines the test methods for determining the melt flow rates (MFR) of thermoplastic materials using an extrusion plastometer. This test is critical for evaluating the viscosity and flow properties of plastics when exposed to heat, providing important data for manufacturers during the molding or extrusion processes.

The standard describes the procedure for measuring the MFR by applying heat to a sample of thermoplastic and forcing it through a die using a pre-set load. It helps determine how the material will perform in various manufacturing conditions, including its behavior under pressure and its ability to form uniform products.

At Pacorr Testing Instruments Pvt Ltd, our Melt Flow Index Tester is designed to meet the requirements of ASTM D1238-13, ensuring that manufacturers receive precise and repeatable results. This test is essential for industries such as automotive, packaging, and consumer goods, where thermoplastic material properties play a key role in product quality and performance.
