Cosmic Epoxy EH21
- Chemical Family
- Epoxy & Epoxy Derivatives
Cosmic Epoxy EH21 is an iron-filled epoxy molding compound provided in a black granular form. It is well-suited for applications requiring EMI (Electromagnetic Interference) and RFI (Radio-Frequency Interference) shielding. This material can be molded through compression or transfer molding processes to create core rods or to encapsulate surface mount and axial leaded inductors. It offers the advantage of simplifying the molding process by eliminating the need for labor-intensive over/under molding.
