Rotational Rheology Laboratory
Rotational rheology testing for polymers, fluids and other materials.
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.
