Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) for Concrete Admixture
1. Sodium naphthalene sulfonate formaldehyde FDN is also called naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Its appearance is the light brown powder. SNF superplasticizer 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.
2. Naphthalene sulfonate formaldehyde is commonly referred to as a superplasticizer for concrete, so it is especially suitable for the prepatation of high- strength concrete, steam-cured concrete, fluid concrete, impermeable concrete, waterproof concrete, plasticized concrete, steel bars and prestressed reinforced concrete. In addition, sodium naphthalene sulfonate formaldehyde can also be used as a dispersant in the leather, textile and dye industries, etc. As a professional manufacturer of naphthalene superplasticizer in China, Longou always provides high quality SNF powder and factory prices for all the clients.

Polycarboxylate Superplasticizer High Range Water Reducers for Cementitious Mortar
1. Super plasticizers are hydrodynamic surfactants (surface reactive agents) for achieving high workability at a reduced w/c ratio by reducing the friction between the grains.
2. Superplasticizers, also known as high range water reducers, are additives used for making high-strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content.
3. PC seris is an advanced Poly carboxylate polymer which has more powerful dispersing effect and shows high water reduction segregation and bleeding, it’s added to the manufacturing of high performance concrete and combined with cement, aggregate, and admixture.

Sulphonated Melamine Formaldehyde(SMF) Superplasticizer for Concrete Admixtures
1. Sulphonated Melamine Formaldehyde (SMF) is also called Sulfonated Melamine Formaldehyde,Sulfonated Melamine Formaldehyde Condensate,Sodium Melamine Formaldehyde. It is another type of superplasticizer besides Sulphonated Naphthalene Formaldehyde and Polycarboxylate superplasticizer.
2. Super plasticizers are hydrodynamic surfactants (surface reactive agents) for achieving high workability at a reduced w/c ratio by reducing the friction between the grains.
3. As water reducing admixtures, Sulfonated melamine formaldehyde (SMF) is a polymer used in cements and plaster- based formulations to reduce water content, while increasing the fluidity and the workability of the mix. In concretes, addition of SMF in an appropriate mix design results in lower porosity, higher mechanical strength, and an improved resistance to aggressive environments.
