Micapoly® UV
Micapoly® UV is a range of composite materials based on muscovite mica and physical UV-filters. Micapoly® UV Crystals are
platelet shaped particles with a mica matrix and a double layer of nanofine Titanium Dioxide or Zinc Oxide, which are sealed
on the mica surfaces with a polymer.
As Micapoly® UV Crystals are platelet shaped, they adhere well on the skin and provide long lasting UV-protection. The
particle size of Micapoly® UV Crystals is around 20 microns. Micapoly® UV Crystals are suitable for colour care applications
and powdery types of sunscreen products for providing UV-protection.
The type of UV-protection achieved with Micapoly® UV Crystals depends on which type of UV-filter is used in it. Micapoly®
UV Crystal TR 22 contains rutile type Titanium Dioxide with a crystal size of 22 nanometers. This provides high SPF and
medium UVA-protection. Micapoly® UV Crystal TR 35 also contains rutile type Titanium Dioxide, but with a crystal size
of 35 nanometers, which provides medium SPF and high UVA-protection. Micapoly® UV Crystal Zn 40 contains Zinc Oxide
with a crystal size of 40 nanometers. This provides low SPF with high UVA-protection.
