Inorganic nanofibrous powders

NnF CERAM® – TiO2

Product description

Titanium dioxide nanofibrous powder is a novel kind of ceramic material produced by industrial production technology operated by Pardam, s.r.o. in the Czech Republic. Nanofibrous products are fully comprised of ceramic basis of titanium oxide with a possible minor amount of porous particles. The properties and characteristics of this inorganic nanofiber material such as a high specific surface area, high collision factor air draft vs. nanofibrous surface “many times higher than regular powders”, predestine TiO2 nanofibrous materials for applications in many products.
