Isobest ® Conductive TapesGeneral description The Isobest ® Conductive Tape is composed of conductive fabric and adhesive. The adhesive is both conductive and non-conductive. Many kinds of tapes such as single-sided and double-sided tape made of conductive fabric, Al, Cu foil, etc. Foil Tape has Anti-corrosion coating. The flame retardant products are in the level of UL94VTM-1 or VTM-0. Thickness from 20 to 680 µmTAPESProperty The flexible and light tape can be easily applied to various small electronic appliances. Excellent shielding effect with low resistance and superior conductivity. Size and material can be diversely adjusted in accordance with customers' requests.

Isobest ® Electromagnetic Wave AbsorberABSORBERGeneral description Electromagnetic noise may affect the electronic devices, andEMC 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/EMCproblems, which is lightweight, thin and flexible. Much absorption loss (dB) provide you with many applications inEMI/EMC field such as mobile phone, LCD cable, military, andproblems of SAR, etc. Conductive and non-conductive adhesive can be produced insingle surface and double surfaces. Moreover, they can be processed in various forms.Concept of AbsorberIn contrast with conductive shielding materials,the reflection of incident waves is very low,because electromagnetic energy absorbed ischanged to heat.
