Bentonit je ílovitá hornina, ktorá vzniká rozkladom vulkanických hornín. Tvorí ho zmes ílových minerálov skupiny smektitu hlavne montmorillonitu. Jeho typickou vlastnosťou je, že pri styku s vodou intenzívne napučiava. Pričom môže dosiahnúť aj niekoľkonásobný nárast objemu.
Existujú draselné (K), sodné (Na) a horečnato – vápenaté (Ca,Mg) bentonity. V našej ponuke nájdete horečnato – vápenaté bentonity.
Pre svoje zaujímavé technické vlastnosti a belosť má bentonit široké využitie. Používa sa ako bieliaca látka v naftárskom, textilnom a potravinárskom priemysle. Plnidlo a pojivo v chemickom a gumárenskom priemysle. V zlievárentsve na prípravu foriem. V poľnohospodárstve ako prímes do hnojív a krmív. Ďalej sa využíva ako súčasť výplachu pri hlbinnom vŕtaní, ako tesniaca látka pri stavbe skládok komunálneho a nebezpečného odpadu a na mnohé ďalšie účely.
