Sarcon® EGR-11F

Silicone Gel Sheet for Absorption of Electromagnetic Wave


1) Effective to absorb and damp a wide range of electromagnetic waves and also effective as a high performance thermal interface material
2) Easily filling small gaps of IC chip surface with soft gel texture
3) Good workability to simply insert the product between circuit board and casing
4) Self-adhesive gel surface does not require any adhesive tape for assembly
5) Extremely low level of low molecular weigh siloxane


1) By placing the product between CPU and heat spreader, it performs dual purposes:
anti-noise countermeasure and good thermal interface.
2) It is recommended for cellular phone, digital still camera, and other mobile devices where anti-noise countermeasure is required.
