Melt Flow Index Tester – Precision Testing for Polymer Flow Properties

 

Introduction

In the polymer and plastics industry, maintaining the right balance between material quality and production efficiency is essential. Pacorr’s Melt Flow Index Tester (MFI Tester) is a trusted solution that helps manufacturers evaluate the melt flow rate of thermoplastic resins with high accuracy. Designed in line with ASTM D1238 and ISO 1133 standards, this instrument provides dependable results that support research, development, and quality control operations across diverse industries.

What Does a Melt Flow Index Tester Do?

A Melt Flow Index Tester determines how easily a thermoplastic material flows when melted. During the test, a polymer sample is heated and forced through a capillary die under specific load and temperature conditions. The weight of the material extruded in 10 minutes is measured, giving the Melt Flow Index (MFI) value.

This parameter is extremely useful because it:

  • Reveals the viscosity and flow characteristics of the material

  • Helps select the correct grade for injection molding, extrusion, or blow molding

  • Ensures batch-to-batch consistency of raw materials

  • Supports international trade and compliance requirements

Why is MFI Testing Crucial?

Polymers with inconsistent melt flow behavior can cause serious challenges during production, leading to:

  • High wastage and rejections

  • Poor dimensional accuracy in molded parts

  • Reduced mechanical strength in final products

By conducting regular MFI testing, industries can:

  • Guarantee consistent polymer performance

  • Save costs by reducing defective batches

  • Achieve global compliance for exports

  • Build stronger trust with end-users through reliable quality

Industries that Rely on MFI Testing

MFI testing has applications across a wide range of sectors, such as:

  • Resin and polymer producers – To maintain raw material grades

  • Automotive industry – For consistent polymer parts in vehicles

  • Packaging sector – For bottles, films, and containers

  • Electrical & electronics – For durable insulation materials

  • Healthcare & medical devices – For reliable polymer-based equipment

Working Method of Melt Flow Index Tester

  1. A sample of the polymer is heated inside the barrel at the desired temperature.

  2. A specified load is applied on the piston.

  3. The molten polymer flows out through the standard die.

  4. The quantity extruded in 10 minutes is collected and weighed.

  5. The measured weight becomes the Melt Flow Index value of the material.

👉 High MFI = Easier flow, low viscosity → Ideal for thin packaging films.
👉 Low MFI = Difficult flow, high viscosity → Suitable for strong molded components.

Understanding Salt Spray Chamber Why Corrosion Testing Matters for Quality and Durability

Image
  Salt spray chambers, also known as salt fog chambers, are essential tools in industrial and material science applications for assessing the durability of materials in corrosive environments. As corrosion remains a primary concern for many industries—from automotive to aerospace and electronics—salt spray testing provides a controlled, accelerated environment that reveals how materials or coatings react over time to salt exposure. This article explores the importance, applications, and benefits of salt spray chambers in ensuring product durability and reliability. 1. What is a Salt Spray Chamber? A salt spray chamber is a laboratory device designed to simulate a harsh, salt-laden environment. The Salt Spray Chamber creates a fine, consistent mist of salt solution, typically a mixture of water and sodium chloride, which settles on the test materials. This controlled environment can replicate years of natural exposure in a fraction of the time, providing essential insights int...
