Description
Boorzuur is een zwak anorganisch zuur dat vaak voorkomt als wit, kristallijn poeder. Het staat bekend om zijn veelzijdigheid in industriële toepassingen dankzij zijn antiseptische, conserverende, vlamvertragende en chemisch stabiliserende eigenschappen. Boorzuur wordt gewonnen uit boraten, voornamelijk afkomstig uit natuurlijke mineralen zoals borax. Het product is wereldwijd inzetbaar in sectoren zoals glasproductie, landbouw, farmacie en chemische industrie.
