Sodium Naphthalene Sulfonate (SNF) in Kingsun

Sodium naphthalene sulfonate formaldehyde (SNF/PNS/FND/NSF) is also called naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Its appearance is the light brown powder.  SNF is made of naphthalene, sulfuric acid, formaldehyde and liquid base, and undergoes a series of reactions such as sulfonation, hydrolysis, condensation and neutralization, and then dried into powder.

As a type of high range concrete water reducer, naphthalene sulfonate formaldehyde is commonly referred to as a superplasticizer. So sulphonated naphthalene formaldehyde has a wide range of applications, especially suitable for the preparation of high-strength concrete, steam-cured concrete, fluid concrete, impermeable concrete, waterproof concrete, plasticized concrete, steel bars and prestressed reinforced concrete. Besides,  sodium naphthalene can also be used as a dispersant in the leather, textile and dye industries, etc. As a professional manufacturer of naphthalene superplasticizer in China, Kingsun always provides high quality SNF products and factory prices for all the clients. Please check the technical parameters of the following different models: SNF-A, SNF-B, SNF-C.

Advantages of Poly Naphthalene Sulfonate (PNS)

  • High water reduction rate. When the water-cement ratio is constant, the initial slump of concrete can be increased by more than 10cm, and the water reduction rate of
    poly naphthalene sulfonate can reach up to 15-25%. More importantly, when the strength and slump are basically the same, The polynaphthalene sulfonate can also reduce the amount of cement used by 10-25%.
  • Good enhancement. PNS superplasticizer has obvious early strength and enhancement effect on concrete, and the strength increase range is 20-60%.
  • Adaptability. Sodium polynaphthalene sulfonate (PNS) is suitable for various specifications and models of cement. And it has good compatibility with other concrete admixtures, for example, it can be combined with an admixture such as a swelling agent, an air entraining agent, and an active admixture such as fly ash.
  • Good durability. It can effectively improve the pore structure of the concrete, thereby greatly improving the durability indexes of concrete such as impermeability, carbonation resistance and freeze-thaw resistance.
  • Safety performance. PNS is a non-hazardous chemical with many characteristics such as non-toxic, non-irritating and non-radioactive. No corrosion effect on steel reinforcement.
