Naphthalene Sulfonate Formaldehyde Condensate (SNF), also known as Poly Naphthalene Sulfonate (PNS) and Formaldehyde Sulfonate Condensate (FDN), is a highly effective water reducer and superplasticizer commonly used in the construction industry to improve the workability and strength of concrete.
It is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate SNF, PNS and FDN etc. Na2SO4 has 3 grades:5% 10% 18% for exporting markets,in domestic we also have 3% 23% Na2SO4 content FDN.It contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable.
PCE superplasticizer is the newest generation superplasticizer used for concrete in domestic and abroad.It is based on molecular designs and adsorption capacity of polycarboxylate,we do R&D and successfully produce water reducing and retention type polycarboxylate superplasticizer for concrete.With initiating systerm and reaction conditions,we achieve high adaptability.Comparing with PNS and other superplasticizer, PCE superplasticizer has many characteristic advantages in technology and performance as following: (1) low dosage, high rate of water reducing; (2) keep concrete good slumption retention; (3) good compatibility with cement; (4) small shrinkage of concrete to keep the stability of volume and durability; (5) environmental in production and usage. Base on above advantages.
