Eccosorb™ JCS-Next

Eccosorb™ JCS-Next

Next Generation High Frequency Elastomeric Absorber

Product Description

Eccosorb™ JCS-Next is a dielectrically loaded silicone rubber electromagnetic absorbing sheet, targeting high frequency noise above 30 GHz. The proprietary filler system is 2 to 3 times as effective as traditional dielectric or carbon filler systems. Eccosorb™ JCS-Next is waterproof, works well in high/low temperatures and meets the requirements for UL94 V-0 rating. The material does not flake or shed and can be die cut to complex shapes from 0.25mm to 3mm thick sheets.
