Inorganic nanofibrous powders

NnF CERAM® – SiO2 (ELSP)

Product description

Amorphous silicon dioxide nanofibrous material is a special funcional material with unique properties represented by fine fibrous structure and high specific surface area. This material is produced using Electrospinning technology which enables to produce very thin fibers 100 – 300 nm in diameter with narrow distribution of fiber diameters. Physical structure of the fibers can be either FLAKES or POWDER (after milling which brings also fiber shortenning). High specific surface area and very high aspect ratio can bring several advantages to new or existing products. This type of material can be produced in lower quantities.
