Original Press Release:

Experimental Silflake 661

Technic EPD has announced the release of Experimental Silflake 661. The flake is mechanically flattened with a bi-modal particle size distribution. The residual lubricant works well in most polymeric applicaitons. The flake has been developed for use in a variety of applications including conductive adhesives, die attach, and other polymeric applications.

The flake exhibits a D50 particle size of 2.5 to 5.5 micron, a tap density of 2.2 to 3.5 g/cm³, with a specific surface area of 1.0 to 1.5 m²/g and a weight loss at 538ºC of less than 0.7%. Benefits of the flake are its bi-model particle size distribution and residual lubricant that works well in most polymeric systems.
