This device, often referred to as the cornerstone of polymer testing, provides critical insights into the flow properties of plastic and polymer materials. At Pacorr.com, we understand the importance of ensuring your products meet exacting standards, and an MFI Tester is essential for achieving that goal.
What is a Melt Flow Index Tester?
A Melt Flow Index Tester is a precision instrument used to measure the melt flow rate (MFR) of thermoplastic materials. This property reflects how easily the material flows when heated under specific conditions of temperature and pressure. The test is standardized under international guidelines such as ASTM D1238 and ISO 1133.
The MFR is expressed in terms of grams of material flowing through a capillary die in a specified amount of time. This value is crucial in assessing the material’s viscosity, molecular weight, and its suitability for different applications.
How Does a Melt Flow Index Tester Work?
The testing process involves the following key steps:
- Material Preparation: A sample of the polymer is prepared and preconditioned according to the required specifications.
- Heating: The sample is placed in a heated barrel to reach a specified temperature (usually between 190°C to 300°C, depending on the material).
- Extrusion: A piston applies pressure, pushing the molten material through a capillary die.
- Measurement: The weight of the extruded material over a set period is recorded to calculate the Melt Flow Rate.

Applications of Melt Flow Index Testing
1. Material Selection
MFI values are used to determine the suitability of raw materials for specific applications. For instance:
- High MFI indicates low viscosity, suitable for injection molding.
- Low MFI indicates high viscosity, ideal for extrusion processes.
2. Quality Assurance
Manufacturers can ensure consistency in material properties, helping maintain product quality and compliance with industry standards.
3. Product Development
MFI data aids R&D teams in modifying formulations to achieve desired properties for new products.
4. Recyclability Assessment
Recyclers can assess the Melt Flow Index Testing characteristics of reclaimed polymers, ensuring they are fit for reuse.
