· NaHF2

Sodium bifluoride (NaHF₂) is an inorganic ceramic compound containing sodium, hydrogen, and fluoride ions. It is primarily used in industrial chemical processing, metal surface treatment, and specialized fluorine chemistry applications where controlled fluoride delivery is required. NaHF₂ is valued in pickling operations, glass etching, and uranium enrichment processes because it provides a stable, solid-state source of fluoride ion that can be precisely metered, making it preferable to corrosive liquid hydrofluoric acid in certain handling scenarios.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
