Product Data Sheet: Ferrite Loading Powder 73399

 

Steward Advanced Materials provides a fully reacted fine particle ferrite loading powder 73399 with an average particle size of approximately 10 µm based on laser diffraction test method.  This energy attenuation powder may be compounded into elastomers for extrusion and roll compacted applications. 

 

Applications include but are not limited to noise suppression for automotive ignition cable, inductive filters, microwave quick-cure, and additive to clean photo-receptor.      

 

Powder loading densities, distribution and thickness of binder have a significant affect on the amount of attenuation.
