Naphthalene Sulfonate Formaldehyde (NSF) is a naphthalenebased superplasticizer, also named Sodium Naphthalene Sulfonate Formaldehyde Condensate ( SNF ) and Poly Naphthalene Sulfonate(PNS) etc. UNF5(sodium sulfate content 18%) / FDN (sodium sulfate content 5%) complies with ASTM C 494, Type F standard for high range water reducer.
Super Plasticizer / Concrete Admixture / Water Reducing Agent. Sodium Naphthalene Sulphonate Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
Naphthalene sulfonate formaldehyde is high range concrete water reducer, commonly referred to as a super plasticizer. So it has a wide range of appliions, especially suitable for the preparation of highstrength concrete, steamcured concrete, fluid concrete, impermeable concrete, waterproof concrete, plasticized concrete, steel bars and prestressed reinforced concrete.
Naphthalene sulfonate, a derivative of sulfonic acid containing naphthalene functional unit, is a naphthalene series super plasticizer with strong dispersing effect on cement particles. SNF superplasticizer has a good effect on the preparation of largefluid concrete, and has obvious effects on castinplace concrete and prefabried components with early strength and high strength requirements.
