Rotational Rheology Laboratory
Rotational rheology testing.
Rotational rheometer testing is available for polymer melts, viscous fluids, dispersions, emulsions and other materials, from ambient to 400°C.
Rotational rheology analysis:
- 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:
Surface finish, weld lines, sink marks, warpage. fibre breakage, excessive draw, melt strength, edge curl, shrinkage, fibre coalescence, splitting, uneven width or thickness, bubble breaks, die drool - Gel Point Determination, Relaxation behaviours, Time and Temperature dependency of Thermosetting,Thermoplastic and adhesive materials
- Rheology solutions for polymer processing
Rheology labs are located in Europe and North America. Samples can be shipped to the labs from most global locations.
