Pumice Powder



Pumice powder is used as a mild abrasive in glass treatments, electronic circuit board scrubbing, dental pastes and industrial hand cleaners. It is also extensively used as a cosmetic exfoliant in facial scrubs and foot scrubs. The pumice particles provide an excellent exfoliating medium which gently removes rough skin leaving it fresh and revitalised. Our pumice products are widely used in the paint and coatings industry as an alternative to traditional fillers such as nepheline syenite, calcium carbonate and silica.
