FAQs
How do I know which rheology test I need?
Describe the material, processing context, temperature range, flow regime, and outputs you need back. We’ll recommend the most appropriate rheology test family and method path.
Which materials can you support?
Rheology testing spans plastics and other polymers, filled systems, adhesives, coatings, soft solids, and thermoplastics for MFR testing. Suitability depends on the method, specimen form, temperature range, and deformation regime.
Can you support elevated temperatures, different shear regimes, or cure/relaxation programs?
Yes—where applicable, programs can incorporate elevated temperatures, multiple shear-rate or frequency conditions, extensional or steady-shear measurements, and cure or relaxation studies.
Where do I find the method-specific details and standards?
They are presented in the Test Methods section of this page under each rheology method category. Click through on the test method of interest for the applicable methods and standards.
What’s included in the report?
You receive an engineering test report (PDF) and digital data deliverables. Exact outputs vary by the selected method and may include viscosity curves, viscoelastic moduli, MFR/MVR values, die swell, extensional viscosity, melt stability, cure data, or relaxation response.
What turnaround should I expect?
Typical turnaround is five business days for standard testing. Turnaround can vary based on the selected method, temperature program, number of conditions, run length, and test volume.
How do I make sure I get the outputs I need?
Tell us what you need back—property values, curves, temperature range, shear/frequency regime, raw data, formats, and any required method or standard. We’ll confirm the appropriate test path and deliverables in the quote before testing begins.
Rheology Test Methods
Rheology testing of materials is essential for understanding how materials flow and deform under applied stress or strain, particularly during processing and end-use conditions. This category of testing is especially critical for polymers in the melt state. Rheological tests provide insights into key properties such as viscosity, elasticity, flow stability, and relaxation behavior, enabling engineers and materials scientists to predict and control material performance during manufacturing processes such as extrusion, injection molding, and curing.
Whether through capillary rheometry to simulate high-shear processing, rotational rheometry to analyze viscoelastic behavior, or melt flow rate testing for rapid quality assessment, these methods are indispensable for material development, process optimization, and product consistency across industries including plastics, coatings, adhesives, biomedical materials, and food products.
The sections below group this testing category into method families, with links to related testing services, key applications, standards context, specimen considerations, test conditions, and measurement details.
