Polymers (Page 4)

As hydrogen becomes a viable source of power, assuring a safe infrastructure for a national transport system is imperative. As part of that effort, we must accurately understand how H2 interacts with permeable polymers used in pipelines, pumps, tanks, and seals. To date, there is not much known about H2 diffusion through polymers in high-pressure...

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...
