Polymers (Page 3)

Optically transparent medical testing devices, such as microfluidic chips and diagnostic components, require precise and delicate welding techniques to maintain their functionality and integrity. The need for clarity and the intolerance of contaminates make most welding approaches unsuitable.  Hot plate welding is too imprecise due to the need to move the parts during the joining...

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...
