Understanding Storage and Loss Modulus with TA Instruments

Batteries & Battery Materials, Composites, Mechanical Testing, Pharmaceuticals, Polymers, Rheology, Thermal Analysis

In the world of material science, understanding the viscoelastic properties of materials is crucial for developing and optimizing products. Two key parameters in this context are storage modulus (E’ or G’) and loss modulus (E” or G”). These parameters provide insights into a material’s stiffness and damping characteristics, respectively, which are essential for applications ranging from polymers and pharmaceuticals to batteries and composites.

10 Questions to Ask Yourself for Successful DSC Use

Biopharmaceuticals, Electronic Materials & Products, Fine & Specialty Chemicals, Pharmaceuticals, Polymers, Thermal Analysis

Differential Scanning Calorimetry is a thermal analysis technique commonly used to characterize materials across a broad array of applications including chemistry, biochemistry, pharmaceuticals, polymers, and more. Differential Scanning Calorimetry (DSC) measures the heat flow in a material as it is heated or cooled over a specified temperature range.

What is Thermogravimetric Analysis?

Composites, Fine & Specialty Chemicals, Food Products, Pharmaceuticals, Polymers, Thermal Analysis

A testament to the march of scientific inquiry, thermogravimetry emerged through the integration of three individual inventions in the 19th and 20th centuries: the electric furnace, the thermocouple, and the microbalance. As a cornerstone of material science, chemistry, and various other industries, thermogravimetric analysis (TGA) has since developed in leaps and bounds. Today, TA Instruments are leading the way in TGA, and we welcome you to join us as we explore the workings and applications of this groundbreaking technique.

Viscometer vs Rheometer: Discover Why a Rheometer Offers More Than Just Viscosity Measurement

Polymers, Rheology

If you’re working with materials that can be flowed, for example within pharmaceutical, food, cosmetics, or petrochemical industries, it’s likely that there is a viscometer in the laboratory that is the go-to instrument for formulation testing or QA purposes. However, does this viscometer give you the whole picture and fully meet all your needs?

What Your Material Specification Sheet Doesn’t Tell You

Mechanical Testing, Polymers, Thermal Analysis

When it comes to selecting materials for your next innovative product, the material specification sheet is likely the first place that you will turn. This document provides core properties measured by the manufacturer and serves as an essential tool for supplier verification and new product development. However, while these sheets are reliable and provide a standard method for comparison, they often fail to tell the whole story.

Linear Viscoelastic Region: Why It’s Crucial in Materials Testing

Engineered Materials, Food Products, Mechanical Testing, Pharmaceuticals, Polymers, Rheology

Our world is brimming with viscoelastic materials: The dough you knead before baking a fresh loaf, the Silly Putty your toddler slaps against the wall, the rubber gaskets that create an airtight seal on an airplane door. Testing those materials by applying controlled deformations (strains) or forces (stresses) at various timescales, temperatures, and/or humidities allows for the optimization of properties and ensures durability and safety.

Characterization Considerations when Sourcing PCR

Polymers, Rheology, Thermal Analysis

Against the backdrop of a plastic waste crisis, the global demand for plastic is set to quadruple by 2060. This has driven a shift toward sustainability and away from linear use models of plastic production. Post-consumer resin (PCR) has emerged as a key player in circular economy initiatives, though ensuring the quality and performance of PCR requires several characterization considerations.

Applying Dynamic Mechanical Analysis (DMA) to Test the Durability of Protective Sports Equipment

Mechanical Testing, Polymers, Thermal Analysis

There is a renewed interest in the durability of protective sports equipment after Patrick Mahomes’ helmet recently cracked apart in -4 degrees Fahrenheit (-20 degrees Celsius) weather. Scientists from TA Instruments ran tests to find out if materials found in protective sports equipment can break due to cold weather.
