Products Description
Sodium Naphthalene Sulfonate Formaldehyde (SNSF), also known as Sodium Polynaphthalene Sulfonate (SNF)
SNSF is a highly sulfonated naphthalene-formaldehyde condensate synthesized via sulfonation, hydrolysis, and polycondensation reactions.
Chemical Classification: Synthetic polymer, anionic surfactant.
CAS Number: 9084-06-4.
Synonyms: Naphthalenesulfonic acid-formaldehyde condensate sodium salt, SNF, PNS (Poly-naphthalene sulfonate).
Physical and Chemical Properties
Appearance: Light yellow to brown powder.
Solubility: Highly soluble in water; insoluble in organic solvents.
pH: 7–9 (aqueous solution).
Thermal Stability: Stable up to 200°C; decomposes at higher temperatures.
Surface Activity: Reduces surface tension due to its anionic surfactant properties.
Key Functional Characteristics
- Superplasticizer: Acts as a high-range water reducer in concrete by dispersing cement particles, improving workability without compromising strength.
- Dispersing Agent: Prevents particle aggregation in suspensions (e.g., ceramics, dyes, coal-water slurries).
- Stabilizer: Enhances colloidal stability in industrial formulations.
- Low Foaming: Minimal foam generation compared to other surfactants.
