BUSINESS SEGMENT AND GEOGRAPHIC INFORMATION

Our reporting structure is comprised of the following operating segments: Advanced Connectivity Solutions (ACS), Elastomeric Material Solutions (EMS) and Power Electronics Solutions (PES). Our non-core businesses are reported in the "Other" reportable segment.


•	Advanced Connectivity Solutions

The Advanced Connectivity Solutions operating segment includes printed circuit board laminate products for high frequency, high performance applications. These products have characteristics that offer performance and other functional advantages in many market applications and serve to differentiate our products from other commonly available materials. These products are sold principally to independent and captive printed circuit board fabricators that convert our laminates to custom printed circuits.

The polymer-based dielectric layers of our circuit board laminates are proprietary materials that provide highly specialized electrical and mechanical properties. Trade names for our printed circuit board materials include RO3000®, RO4000®, RT/duroid®, ULTRALAM®, RO2800®, LoPro®, COOLSPAN® and TMM® laminates. All of these laminates are used for making circuitry that receive, transmit, and process high frequency communications signals, yet each laminate has varying properties that address specific needs and applications within the communications market. High frequency circuits are used in the equipment and devices that comprise wireless communications systems, including cellular communications, digital cellular communications, paging, direct broadcast television, global positioning, mobile radio communications, and radar for both aviation and automotive applications.


•	Elastomeric Material Solutions

The Elastomeric Material Solutions operating segment includes polyurethane and silicone foam as well as solid products manufactured in roll stock, sheet, and molded formats. These materials have characteristics that offer functional advantages in many market applications which serve to differentiate Rogers' products from other commonly available materials.

Elastomeric Material Solutions products are sold globally to converters, fabricators, distributors and original equipment manufacturers (OEMs) for use in general industrial applications, portable electronics including mobile internet devices, consumer goods, mass transportation, construction, printing applications and other markets. Trade names for our Elastomeric Material Solutions include: PORON® Microcellular Urethanes used for making high performance gaskets and seals in vehicles, portable communications devices, computers and peripherals; PORON® cushion insole materials for footwear and related products; PORON® healthcare and medical materials for body cushioning and orthotic appliances; R/bak® compressible printing plate backing and mounting products for cushioning flexographic plates for printing on packaging materials; PORON® and XRD® for high impact cushioning protection; Rogers BISCO® silicone foams, solids, sponge and extrusion products for flame retardant gaskets, seals and cushioning applications in communications infrastructure equipment, aircraft, trains, cars and trucks, and for shielding extreme temperature or flame; and eSORBA® urethane foams used in portable communications, entertainment devices and other industrial applications.

We have two 50% owned joint ventures that extend and complement our worldwide business in Elastomeric Material Solutions. Rogers INOAC Corporation (RIC), a joint venture with Japan-based INOAC Corporation, manufactures high performance polyurethane foam materials in Mie and Taketoyo, Japan to predominantly serve the Japanese and Taiwanese markets. Rogers INOAC Suzhou Corporation (RIS) was established in 2004 with INOAC Corporation and provides polyurethane foam materials primarily to the Asian marketplace.


•	Power Electronics Solutions

The Power Electronics Solutions operating segment is comprised of direct bond copper (DBC) ceramic substrate products and busbar power distribution products. We believe that our advanced, customized components enable the performance and reliability of today’s growing array of power electronic devices and serve to increase the efficiency of applications by managing heat and ensuring the reliability of these critical devices used in converting raw energy into controlled and regulated power that can be used and managed.

Trade names for our Power Electronics Solutions products include curamik® ceramic substrates and RO-LINX® products. Curamik® ceramic substrates are used in the design of intelligent power management devices, such as insulated gate bipolar transistor (IGBT) modules, which enable a wide range of products including highly efficient industrial motor drives, wind and solar converters and electric and hybrid electric vehicle drive systems. RO-LINX® products are used in high power electrical inverter and converter systems for use in mass transit (e.g. high speed trains); clean technology applications (e.g. wind turbines, solar farms and electric vehicles) and variable frequency drives for high to mid power applications.


•	Other

The remainder of operations are accumulated and reported as our Other business, which consists of elastomer components, floats and inverter distribution activities. Elastomer components are sold to OEMs for applications in ground transportation, office equipment, consumer and other markets. Trade names for our elastomer components include: NITROPHYL® floats for level sensing in fuel tanks, motors, and storage tanks and ENDUR® elastomer rollers and belts for document handling in copiers, printers, mail sorting machines and automated teller machines. Inverters are sold primarily to OEMs and fabricators that in turn sell to various other third parties primarily serving the portable communication and automotive markets. In 2015, the Other businesses included the Arlon polyimide and thermoset laminate operations, which was sold in December 2015.
