ISO 1133-1

ISO 1133-1 is an international standard that specifies methods for determining the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastic materials. These tests are essential for assessing the flow properties of plastics when subjected to high temperatures, providing valuable insights into the material's viscosity and processing behavior.

The standard outlines detailed procedures for conducting the test, including the preparation of the plastic samples, the testing temperature, and the load applied during the process. The results help manufacturers understand how thermoplastics will behave during molding and extrusion, aiding in quality control and ensuring consistency in production.

At Pacorr Testing Instruments Pvt Ltd, our Melt Flow Index Tester complies with ISO 1133-1 standards, delivering accurate measurements of MFR and MVR. These tests are vital for industries such as automotive, packaging, and electronics, where precise control over material flow properties is crucial for producing high-quality products.
