Isobest Shield Foam Gasket Features Structure Isobest Shield foam gasket is made by conductive fabric and polyurethane foam. These gaskets provide a very low surface resistivity of 0.1 /. Conductive Fabric Width GASKETS Use of conductive adhesive tape on gaskets of all sizes realizes more effective shielding/grounding than ever. These gaskets are more flexible than conventional products so they fit any uneven surfaces smoothly and securely even with a low compressive force. High-resilience polyurethane foam is used as the core material; the resilience is 20% higher than that of conventional products. Polyurethane Foam Pressure-Sensitive Adhesive (PSA) Thickness Customer specified size variation permits the best-suited choice for each application. High workability. Like conventional products, they can be easily cut with scissors so that, as shielding/grounding materials, they meet any kind of application need. Gasket cross section (enlarged) Highly flame retardant

Isobest Conductive EMI Cushion General description Isobest Conductive EMI Cushion consists of conductive foam and a conductive pressure sensitive adhesion tape. The numberless cells of foam are plated with Copper, Nickel, Silver and it is very flexible and provide good shielding effectiveness. It is very easy to mount on the substrates due to conductive tape attached to the back side of Cushion. It can be easily applied with various shapes. Thicknesses from 0.30 to 9.00 mm CUSHIONS Application Shielding/ Grounding for electronic equipment and other electronic appliances Grounding for chassis Grounding enhancement for connectors and casings Shielding of PC outer surface Connector Grounding of PC inner surface Grounding for chassis of LCD (TV, monitor, mobile phone) D-sub cushion
Isobest Electromagnetic Wave Absorber ABSORBER General description Electromagnetic noise may affect the electronic devices, and EMC has been recognized as one of the serious social problems. Isobest Electromagnetic Wave Absorber is a wide band (30MHz~10GHz) RF wave absorber for preventing EMI/EMC problems, which is lightweight, thin and flexible. Much absorption loss (db) provide you with many applications in EMI/EMC field such as mobile phone, LCD cable, military, and problems of SAR, etc. Conductive and non-conductive adhesive can be produced in single surface and double surfaces. Moreover, they can be processed in various forms. Concept of Absorber In contrast with conductive shielding materials, the reflection of incident waves is very low, because electromagnetic energy absorbed is changed to heat.
Application Radiated noise suppression in all kind of electronic equipment and its internal interference problems Mobile communications equipment, Wireless equipment Intra-system application to suppress noise in quasi microwave (1~3GHz) range Military Reduction of emissive noise from PCB boards Attached on inside of the housing case Reduction of emissive noise from CCD control circuit boards Put on flat cables Reduction of emissive noise from CCD control circuit boards Reduction of emissive noise from PCB boards
