Polymers

Auto manufacturers and suppliers need a valid, reliable way to detect flaws in electric vehicle battery enclosures, or modules. EWI has developed an inexpensive testing method with demonstrated feasibility! Our team validated an EV battery testing procedure involving colorimetric chemical reagents and a reactive gas. It’s a high-resolution marking method that’s faster and clearer than...

For certain manufacturing applications, making selected components out of plastic via 3D printing has great advantages. A significant disadvantage for high-volume production, however, is the slow extrusion rates of polymer materials. EWI has developed a new technique using ultrasonic power that can increase the speed of polymer extrusion. This method is discussed in Speeding Up...

The material properties of polymers like plastics and elastomers can be affected by their environments and weaken over time. These changes can lead to premature product failure. It is, therefore, important to perform material characterization and age testing prior to making a new product. EWI Senior Technology Leader Jeff Ellis has written Predicting Polymer Service...
