Ag Glassflake

Conductivity and decorative effects

AgFlake

Agflake glass flakes are thin borosilicate platelets encapsulated in silver. It is used for functional purposes as a conductive filler. In contrast to equivalent pure metal fillers, Agflake is lightweight, and high conductivity can be achieved at low loadings.

Applications

• Conductive adhesives (ACA, ICA)
• Conductive films (ACF, ICF)
• Conductive compounds
• Conductive Inks
• EMI/ RMI shielding
• 3D printing

 

Advantages

• High conductivity even at low loadings
• High surface area additive
• Lower density than pure metal flakes
• Lower cost than pure Silver flakes
• Free flowing flakes, easy to process
• Good flake alignment can be achieved
• High thermal stability
• Ag oxidation does not adversely affect conductivity

 

Products Glassflake AgFlake

AgFlake is based on 2 micron thick ECR borosilicate glass flakes coated with high loadings of silver (30, 35wt %) and are available in two particle size diameters. It is also possible to coat thicker flake and flake within our Nanoflake range, and at varying particle diameter distributions.
