Melt Flow Index Tester – Accurate Polymer Testing with Pacorr
In the modern plastics and packaging industry, quality, reliability, and compliance are the foundation of success. At Pacorr Testing Instruments Pvt. Ltd., we provide advanced Melt Flow Index Tester (MFI Testers) that enable manufacturers, processors, and research labs to ensure their thermoplastic materials meet international standards.
Our instruments are designed in line with ASTM D1238, ISO 1133, and other global guidelines, making them the preferred choice for industries where polymer quality assurance is critical.
What is a Melt Flow Index Tester?
A Melt Flow Index Tester is a laboratory instrument that measures the rate of flow of molten thermoplastic material through a capillary under controlled temperature and load conditions. The result is expressed as grams per 10 minutes (g/10 min), also known as Melt Flow Rate (MFR).
The MFR is directly related to the molecular weight and viscosity of the polymer. This data is essential for predicting how a material will perform during injection molding, extrusion, and blow molding.
Why Melt Flow Index Testing Matters
Ensures Material Consistency – Detects variations in polymer quality before production.
Optimizes Manufacturing – Helps processors fine-tune molding and extrusion parameters.
Supports International Compliance – Meets ASTM, ISO, and JIS standards for exports.
Reduces Wastage – Prevents defects, rework, and material rejection.
Enhances End-Product Reliability – Ensures packaging, automotive parts, and consumer goods perform as expected.
