Glass flake looks like
microscopic pieces of broken window pane. The high aspect ratio
of flakes, compared to fibers or granular fillers, imparts unique
properties to materials to which they are added. Care has to be
taken in choosing the addition level and size distribution to
obtain the required result and for the optimization of a
particular characteristic. Glass flake is extensively used as an in-situ
barrier in coating and polymers to improve reinforcement and
thermal properties. Sub-micron thickness glassflake is used as
aunique substrate for metal oxides to product pigments.
Glassflakes are characterized according to the flake thickness,
particle seze diameter and glass composition
