Intertek MSG provides Rotational Rheometer Testing Capabilities. Applications include polymer melts, viscous fluids, dispersions, emulsions etc from ambient to 400°C. Applications for rotational rheology include:

• Very low shear-rate analyses provide information on molecular weight
• Gelation times can be determined for a wide range of materials, including epoxy resins and adhesives
• Melt Stability in air or nitrogen atmosphere and/or against a range of metal surfaces
• Effect of temperature on flow properties at fixed deformation rates
• Thixotropy through controlled stress measurements of structured fluids
• Yield stress, recovery, thixotropy, flocculation of multi-phase systems
• Prediction of polymer melt processing behaviours e.g. surface finish, weld lines, sink marks, warpage. fibre breakage, excessive draw, melt strength, edge curl, shrinkage, fibre coalescence, splitting, uneven width / thickness, bubble breaks, die drool
• Gel Point Determination, Relaxation behaviours, Time and Temperature dependency of Thermosetting,Thermoplastic and adhesive materials
