Keep Flow Under Control Flow properties of molten plastics are a critical characteristic requiring good knowledge and control. The Instron® Melt Flow Testers are specifically designed for easy and accurate measuring of the Melt Mass-Flow Rate (MFR) and the Melt Volume-Flow Rate (MVR). CEAST Melt Flow Testers range from systems that perform a simple manual test procedure to semi-automated testing systems performing multiple weight tests. Why Measure Melt Flow? MFR represents a typical index for characterizing thermoplastics. Which is the Right System for My Test? What Results Do You Need?...

Meet My Testing Needs Thermoplastics are versatile materials used to manufacture a variety of products, ranging from toys to shopping bags, from kitchenware to automotive parts, from textile fibers to medical consumables. They are often handled as hot viscous fluids in the Chemical and Manufacturing Industry because they are mixed and shaped in the molten state within typical temperatures from 100 to 400°C (212 to 752°F). Incoming Material Acceptance Are you a raw material producer? If not, you may have one or more suppliers for the materials used in your process. Are the properties of each...

Product Development Process Optimization If your laboratory is working with thermoplastic materials, you will need to check the flow properties by comparing values as per standard industrial procedures. The MFR is typically part of the data sheet of a material and can be used to indirectly evaluate other properties. In fact, it’s an index for molecular weight, physical and chemical degradation, and quality of additives and compounds. FRR results indicate qualitative differences for Molecular Weights Distribution and Non-Newtonian Flow Behavior. Is your lab’s testing activity aimed at...

Selecting the Right Melt Flow Tester for Your Applications Procedure A (ISO 1133-1/-2*, ASTM D1238) Widely used for basic quality control, this is a mass-measurement method where the operator must weigh portions of the extruded material cut at precise time intervals. The Melt Mass-Flow Rate (MFR) result is directly obtained by dividing the Extrudate Mass by the corresponding Extrusion Time. Standards recommend that this procedure be limited to MFR ranging from 0.15 – 50 g/10 min. Procedure B (ISO 1133-1/-2*, ASTM D1238) As the most common procedure for Melt Flow tests, this is a...

Single-Weight Tests According to Procedures A, B, and C Single-Weight Tests According to Procedures A, B, and C with Controlled Compacting and Purging Single-Weight and Multi-Weight Tests According to Procedures A, B, C, and D *Note on ISO 1133-2 This part of the ISO standard for Melt Flow Tests was introduced at the end of 2011. It is aimed at ensuring MFR results with good accuracy also for materials that are particularly sensitive to moisture or time-temperature history. It specifies tighter requirements for temperature accuracy and stability of Melt Flow Testers and very accurate...
