Overview of Melt Flow Index Tester

Pacorr’s Melt Flow Index Tester is a precision-engineered instrument designed to determine the flow properties of thermoplastic polymers. By accurately measuring the melt flow rate (MFR) or melt volume rate (MVR), this equipment helps manufacturers assess material behavior under standardized temperature and pressure conditions. Ideal for plastic processors, compounders, and quality control labs, Pacorr’s MFI Tester ensures compliance with ASTM D1238 and ISO 1133 standards.

Understanding the Melt Flow Index (MFI)
The Melt Flow Index (MFI) is a key parameter that defines the ease of flow of a molten thermoplastic material. It is measured in grams per 10 minutes and is critical in assessing the processing performance of materials in injection molding, extrusion, and blow molding operations. A higher MFI indicates lower viscosity, while a lower MFI means higher resistance to flow.

Pacorr's Melt Flow Index Tester offers advanced digital and computerized models that provide accurate, reproducible results with minimal operator intervention. This helps quality analysts determine batch-to-batch consistency, material degradation, and suitability for specific applications.
