Durable polycarbonate from Bayer protects sensitive electronics in rugged applications

PITTSBURGH, March 3, 2015 /PRNewswire/ -- Products to be used in rugged environments ranging from industrial to outdoor to medical have one clear thing in common – the need for toughness and durability. This is the "real-world" situation InHand Electronics faced when developing its own Hydra-F6™ tablet and the display unit for the Praemittias Systems' Wolfhound Cooperative Radio Direction Finding System^® (Wolfhound).

"For our rugged tablet and radio system we required a commercially available material that was durable, moldable, resistant to chemicals and withstood impact testing," explained Tien Chuang, senior mechanical engineer, InHand Electronics, Inc. "We found what we were looking for in Makrolon^® 9415 polycarbonate from Bayer MaterialScience."

Makrolon^® 9415 polycarbonate is an easy-release, high-viscosity and flame-retardant grade. It is 10 percent glass-fiber reinforced and meets UL 94 V-0 rating at 1.5 mm and 5VA rating at 3.0 mm. This material was originally used by InHand Electronics in 2011 for its earlier-generation T3 model and provides superior performance in multiple industries due to its light weight, durability and good thermal properties.

"We worked with InHand for about a year to identify the right material for the job," said Anthony Leo, field market development, Polycarbonates – Northeast, Bayer MaterialScience LLC. "Bayer provided InHand with information regarding material properties and assisted with color matching and standards compliance."

Standards compliance was an important consideration when developing the Hydra-F6™ tablet. The device offers the versatility and portability of a consumer tablet with the durability and long production life of a MIL-SPEC mobile device. With a size of 8.42 inches by 5.92 inches by 0.98 inches and weighing 1.5 pounds, the tablet meets challenging MIL-STD-810G, MIL-STD-461F and IP67 environmental requirements. The housing, molded from Makrolon^® 9415 polycarbonate, borders the 7-inch WSVGA sunlight-readable display with touchscreen, brightness control and automatic display rotation. It is available as a commercial, off-the-shelf tablet, or it can be semi or fully customized for application-specific needs.

InHand created a handheld display head for the Wolfhound device. The display head provides a touch-screen LCD in a durable, lightweight package tethered to the main Wolfhound unit, enabling users to easily interact with the system while in environmentally harsh (e.g. wet, hot, cold, humid and/or dirty) conditions. Incorporating an integral GPS for geolocation, the system detects signals of interest and visualizes the information on the handheld display.

The Wolfhound display head required a lightweight material (for portability) that was also tough and satisfied MIL-SPECs. To help achieve this, the display head relies on the superior properties of Makrolon^® 9415 polycarbonate.

"These applications benefit from the customization options and outstanding toughness of the polycarbonate, as well as its processability," said Kevin Dunay, market segment manager, Electrical, IT & Appliance, Polycarbonates – North America, Bayer MaterialScience LLC. "With the injection molding process, InHand had various options for the geometry of the final product design. This design freedom was another important consideration for selecting Makrolon^® plastic."
