Durable grade of Bayer MaterialScience’s Bayblend® PC/ABS blend resin helps keep power flowing to soldiers in the field


Bayblend PC/ABS blend chosen for its outstanding properties including temperature resistance and dimensional stability


October 17, 2007

Pittsburgh, October 17, 2007 — Modern soldiers on the front lines depend on portable electronics to stay safe and connected with tools such as sensors, laptops and satellite phones. Generating the power necessary to keep sophisticated electronics up and running in the field has traditionally been a task left to battery packs that are short-lived, heavy and a hassle. An innovative solution from the UltraCell Corporation of Livermore, Calif., is a lightweight, high power density fuel cell system that is designed to withstand heavy abuse in the field thanks to a highly engineered grade of Bayer MaterialScience’s (BMS) LLC Bayblend® PC/ABS blend resin.

UltraCell uses Bayblend KU 2-1514 non-reinforced, flame-retardant PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) resin for the rugged housing of its XX25 reformed methanol micro-fuel cell. The resin was chosen for its high heat resistance and outstanding processing behavior, as well as its combination of dimensional stability, stiffness and very high impact resistance over a broad range of temperatures. The material is also resistant to chemicals, including mineral acids and a large number of organic acids, as well as aqueous saline solutions.

The XX25 can provide uninterrupted 25 Watt power for more than 8 hours on a single cartridge of methanol and weighs only 2.5 pounds. The rugged fuel cell system has been designed to survive demanding environments such as jungle, desert and arctic conditions, and can provide uninterruptible power to electronic systems for hours, days or weeks using “hot-swap” cartridge capability.

“We chose Bayblend KU 2-1514 PC/ABS blend resin for the protective housing of the XX25 because of its combined thermal properties, durability, resistance to cracking and high impact strength. It had to pass an array of Mil-spec testing including drop and environmental tests, as well as being blasted with sand and dust to simulate desert conditions,” said Dr. Kenneth Newell, vice president of engineering, UltraCell Corporation. “The Bayblend resin has demonstrated very repeatable quality in the injected parts, and the color has been consistent. Our military customers are very impressed with the ruggedness achieved with our chassis material.”

Another notable performance advantage of Bayblend KU 2-1514 PC/ABS blend is that it can be recycled, or incinerated with energy recovery after use.

“At Bayer MaterialScience we are thrilled to be a part of a sustainable technology that not only improves the conditions for soldiers in the field, but also moves forward to replace batteries with fuel cells derived from renewable resources,” said Gerald DiBattista, market segment leader, IT, Electrical/Electronics Polycarbonates, Bayer MaterialScience LLC. “We worked tirelessly with UltraCell to find the right material in our extensive portfolio that met all of the requirements for this breakthrough product.”

UltraCell’s XX25 fuel cell system is currently undergoing military field trials, which are scheduled to conclude in late 2007, according to Newell. In addition, UltraCell just completed the commercial launch of its XX25A system for powering first responders, ruggedized laptops and remote radio and satellite communications.
