Melt Flow Index Testers
Extrusion Plastometers for Rapid Incoming Material Acceptance and Efficient Process Control
Instron® MFi Series of melt flow index testers are specifically designed for easy and accurate measuring of Melt Flow Rate (MFR) and Melt Volume Rate (MVR) according to Melt Flow Rate testing procedure A, procedure B and procedure C determined by ASTM D1238 and ISO 1133 standards.
Why Melt Flow Testing Optimizes Your Productivity
Melt flow testing is simply a measure of the flow of a polymer when melted. The result of a melt flow test, called the melt mass-flow rate (MFR) or melt volume-flow rate (MVR), is defined as the amount of mass or volume of a polymer that flows through a small die at a specified temperature and pressure.
Accelerated expectations for rapid material processing and delivery continue to ride. Avoiding production bottlenecks is a key to secure your profit and gain a competitive advantage in the market. The advanced technology of Instron new Melt Flow Index Testers minimize costly errors and increase your productivity.
Smart User Interface
