Our silica wool is made from pure fused quartz fiber: amorphous, continuous, tangled, white, odorless, with no volatile component and no shot. Length, shape and arrangement of fibers give the wool its curly appearance preventing compression of the padding and improves its desired insulating properties.

Glass wool is often used as filter material in analytical processes and as supporting substance for drying agents in drying towers (e.g. to prevent “caking” in P2O5).

Filter aids transform difficult precipitates and colloidal particles into a form which can be easily filtered. When slimy and strongly lyophilic, swelling precipitates are involved, the fibres of the filter flocs prevent formation of a continuous, impermeable layer on the filter. The resulting filter cake remains porous and permeable, and clogging of the filter is prevented.
