Electrical Insulation, Conduction and EMI Shielding

Device failures caused by interference or noise from electromagnetic energy are increasing due to the growing number of products that contain sensitive electronic components. The smaller size and faster operating speeds of today’s electrical and electronic components make it more difficult to manage performance. Rogers offers an array of solutions for electrical insulation, conduction and EMI/RFI shielding to protect and insulate devices from electrical interference.

Electrical Insulation

Coil Insulation

ARLON Coil Insulation products, field tested for over 50 years, provide excellent electrical insulation for large rotating machines and traction motors, even in the most challenging operating conditions.

Insulating Tapes

• ARLON silicone self-fusing tapes are produced from specially formulated silicone rubber that allows them to bond only to themselves. The permanent bond provides an insulating barrier resistant to moisture, ozone, and corona over a wide temperature range. ARLON self-fusing tapes provide superior electrical insulation with a minimum dielectric strength of 300 VPM at 180°C (356°F).
• DeWAL pressure sensitive tapes combine the strength, durability and versatility of the DeWAL brand family of high quality film products with proprietary formulations of silicone, acrylic, or rubber-based adhesive systems. DeWAL offers simple glass cloth tapes, surface treated skived PTFE and FEP adhesive tapes to solve all electrical insulation demands. These products are often used in the oil and gas industry for downhole cable splicing and repair.

Electrical Conduction

COOLSPAN® Thermally & Electrically Conductive Adhesive (TECA) is a thermosetting, epoxy based, silver filled adhesive film used to bond circuit boards to heavy clad metal backplanes, heat sink coins and RF module housings. Conductive adhesive films provide a convenient and reliable approach used to bond high power circuit boards to heavy metal backplanes or heat sinks.

EMI Shielding

ARLON Thermabond® electronic adhesives are a unique class of elastomeric thermal interface materials that provide thermal-mechanical stress decoupling and a reliable heat transfer path. With Thermabond, adjoining components move freely during operation -- preventing stress build-up created by CTE mismatch. Thermabond is available in a range of thermal conductivities, including an electrically conductive line for ground plane continuity, ESD grounding, EMI shielding and RF shielding.

BISCO® Silicone EC-2130 electrically conductive silicones reduce EMI and RFI at frequencies above 10 Ghz within compact handheld electronics, communication devices, electronic enclosures and laptop computers. These silicone EMI shields are formulated to have a low durometer, which creates the low compressive forces needed for challenging product designs.
