Applications & Use Cases
- ▸ Reinforcing filler in rubber compounds, including tire treads and technical rubber goods, where it improves tear strength, abrasion resistance and rolling-resistance performance versus carbon black.
- ▸ Anticaking and free-flow agent for powders, granular feeds and dry-mix formulations, where its high surface area absorbs surface moisture and keeps particles flowing.
- ▸ Matting and flatting agent in coatings, inks and overprint varnishes to reduce gloss and produce controlled satin or matte finishes.
- ▸ Rheology modifier, thickener and anti-settling additive in liquid systems such as paints, adhesives, sealants and unsaturated polyester resins.
- ▸ Carrier and de-dusting agent for liquid actives in agrochemical and industrial powder formulations, converting liquids into free-flowing solids.
