Materials at the heart of medical device

During sudden cardic arrest, a safe, reliable and effective automated external defibrillator (AED) device can be a lifesaver. AED manufacturers desire the same characteristics when choosing materials for their products.

Automated external defibrillator
The Powerheart® G5 device’s battery case and housing from Cardiac Science uses Bayblend® FR3010 PC+ABS blend resin from Covestro.

Task

Cardiac Science Corporation wanted to update the technology and design of its next-generation Powerheart® G5 AED. The company sought a material that offered strength, impact resistance and an Underwriters Laboratories (UL) flame rating for the device’s battery case and housing.

Challenge

Because the Powerheart® G5 AED is used by emergency service and military customers in rugged conditions, the device must be durable without sacrificing life-saving features. The AED outershell had to pass drop and durability tests while meeting quality protocols and product development timelines.

Solution

The company chose Bayblend® FR3010 polycarbonate/acrylonitrile butadiene styrene (PC+ABS) blend resin from Covestro for its excellent impact performance, overall strength and UL flame rating of 94 V-0. The corporate color palette for Cardiac Science was color-matched using pre-colored plastics created via LEDA® compounded color technology from Covestro. The company’s unique and distinct orange and gray corporate color hues were matched at Covestro’s Color Competence and Design Center.

Bayblend® (PC+ABS- Blend; PC+ASA-Blend) - Discover the best of both worlds

Bayblend® FR3010 PC+ABS blend resin is durable and offers strong impact resistance.

The material offers high strength and heat resistance, meaning it is not easily damaged by heat.

The device’s battery case and housing material has a UL flame rating, important since it contains all the electronics and acts as a protective cover for the internal components.

Bayblend® FR3010 PC+ABS blend resin can be easily processed by injection molding.
