OP-7400 offers hybrid absorber/thermal management material that is used for EMI mitigation. Designed using silicone gel binder that imparts inherent tack typical of standard thermal gap fillers. Filler particle composition imparts both excellent thermal conductivity and good EMI suppression in the microwave frequency.

The proprietary formulation of OP-7400 is RoHS compliant and halogen-free, providing extra reassurance in applications where hazardous substances are forbidden.
