Overview During the formulation and manufacturing of polymeric materials for medical devices, the materials go through multiple stages and undergo many transformations. At each of these stages new additives might be added or the material is exposed to physical factors like heat which impacts the chemical nature of the ingredients. Subsequently, during the final product…
Overview Crude oil is typically extracted as a single organic liquid phase from the reservoir. However during transportation, a drop in the temperature can cause the higher molecular weight paraffins or waxes to separate into the solid phase. The temperature at which the first wax crystals appear during cooling is commonly known as the…
Overview Thermosetting materials, such as epoxy, have been widely applied in many areas including automotive, aerospace and electronics industries in the form of surface coating, structural adhesives, advanced composites and packaging materials. These kind of materials pose high mechanical strength, high temperature stability and good solvent resistance. Unlike thermoplastic polymers, the process of thermosets…
Overview The viscoelastic properties of polymers play a critical role in the different stages of polymer processing operations, whether it is melting and extrusion or the performance of the final product. On most polymer data sheets, these properties are presented in the form of a melt flow index. However, this simplistic approach is inherently…
Overview Have you been tasked with answering any of the following or similar questions? Will our product flow under these conditions? What are the optimal processing conditions? Will this formulation be accepted or rejected by our sensory panel? What is the working time for this adhesive? How strong is the final composite sample? Will…
Overview You will gain insight into the role of chemical characterization in newly modified EU Medical Device Regulations (EU MDR) impacting ISO 10993. This webinar highlights how you can leverage HRMS to overcome characterization challenges.
Overview In this webinar, we address applications of rheology fundamentals in the testing of biomaterials and biomedical devices. The discussion focuses on two approaches to rheological testing – unidirectional testing and dynamic oscillatory testing.
Overview Rheo-microscopy combines rheological measurements with simultaneous investigation of the material’s microstructure, and how it may evolve in response to external stresses or strain fields. This webinar will showcase the power of rheo-microscopy for an accurate interpretation of rheological data in the context of three case studies, each on a different material and using…
Interfacial Rheology: Fundamental Overview and Applications Overview Interfacial rheology dominates the behavior of many complex fluid systems. Whether the system is characterized by a fluid-fluid interface or fluid-air interface, these characteristics influence the behavior of biological systems, oil recovery, personal care products, food and more. Learn the basic forces that drive interfacial dynamics and…
Designing New Materials for Additive Manufacturing: Vat Photopolymerization Overview 3D printing, or additive manufacturing (AM), provides opportunities to create previously unattainable geometric objects through layer-by-layer fabrication. Novel macromolecular structures and synthetic methods coupled with unique printing methods lead to 3D part generation with micron-scale resolution and tunable to emerging technologies. By tuning polymer structure, printing…
An Introduction To High Pressure Rheology High pressure rheology explores phenomena that are not accessible at ambient laboratory conditions. Three of the advantages of using a pressure rheometer cell include a controlled environment for volatile fluids, saturating fluids with soluble constituents, and exploring new phase space using a combination of temperature and pressure.
Randy H. Ewoldt: Experimental Challenges of Shear Rheology, How to Avoid Bad Data How do you know when to trust your rheology data? How do you avoid bad data? Is there a checklist? Can you co-plot quantitative experimental boundaries against measured data? This presentation will discuss techniques for identifying and minimizing experimental errors and for…
