We offer a broad range of electromagnetic materials, such as metal alloys and ferrites that are utilized into coatings and other elastomers and resin systems for EMI, RF and microwave absorption. Lightweight materials are available with aspect ratio for weight reduction, as well as spherical particles with tailored particle distributions to optimize loading concentrations and maximize performance. We have the capability to create platelet shaped particles from magnetic alloys. If required, we can enhance corrosion resistance and dielectric properties through proprietary treatment processes. Magnetic materials for high-temperature applications are also available, upon request. Custom materials can be developed to support your unique applications and requirements. Applications include (but are not limited to): Coatings to attenuate and absorb energy; Loaded into elastomers, thermoplastics and other polymer resin systems for extrusion or thermo-moldable parts and components; Thin flexible EMI tape for shielding and absorption; Microwave quick-cure or heat susceptors; Automotive ignition cable for RF absorption; Thermoplastic welding; Magnetic tagging
Our stainless steel flakes are manufactured from 316L and 434L. However, many other compositions can be produced if required. Stainless steel flakes are finely divided with a uniform particle size that can be adjusted to customer specifications. These flakes are recommended for use in water and solvent based paint or coating systems.

Ferrite Loading Powder 73399 is a small average particle manganese-zinc (MnZn) ferrite compatible for loading into various resin systems for EMI absorption. Custom variations can be produced - including changes in chemistry and particle size distribution. Applications include, but are not limited to, noise suppression for automotive ignition cable, inductive filters, microwave heating, and magnetic susceptibility for detection. The powder loading densities, distribution and thickness of the product have a significant affect on the amount of attenuation.
