Why dose snow appear white, although the composition consist of two
colorless components AIR and WATER.
Snow is formed by precipitation of small columnar ice crystals from water at
Sub-zero temperatures in the upper atmosphere.
During formation, air is trapped inside the Crystal Latices, and because
the refractive indices of Air and water / ice are different
[ICE ni-1.3, AIR na=1.0].
Light is effectively scattered back within the Matrix.
Thus, when sunlight impinges on the snow structure, the majority of the
light is scattered back or reflected out snow its VERY CHARACTERISTIC
white appearance.
HIQUE 'mimics' this natural snow structure, the microstructure of HIQUE
consists of a very small polymer bead with a hollow void, filled with air.
Refractive index of the polymer is np=1.5 and Air is na=1.0.
Thus whem light hits the polmer, it appears BRILLIANT WHITE.
Opaque polymer HIQUE - as white as the driven snow, enhancing our
beautiful world!
