ISO 1133-2

ISO 1133-2 is an extension of the ISO 1133 standard, focusing specifically on thermoplastic materials that are sensitive to time-temperature history and/or moisture content. This standard provides additional guidelines and procedures for determining the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of such sensitive thermoplastics.

The test method ensures that the measurement process takes into account factors like moisture content or material degradation due to prolonged exposure to heat, which can affect the accuracy of the flow rate data. By controlling these variables, ISO 1133-2 ensures that test results reflect the true processing behavior of the material.

At Pacorr Testing Instruments Pvt Ltd, our Melt Flow Index Tester is designed to comply with ISO 1133-2, delivering precise and reliable results for materials that are moisture-sensitive or prone to degradation during testing. This is crucial for industries that require accurate assessments of thermoplastics, ensuring consistent material quality and performance during production processes.
