供应Sodium naphthalene formaldehyde is also called naphthalene based superplasticizer, poly naphthalene sulfonate formaldehyde, SNF powder, PNS powder, FDN powder, NSF, naphthalene highl range water reducer, SNF superplasticizer, NSF powder, naphthalene formaldehyde, sodium naphthalene sulfonate, naphthalene sulfonate salt, superplasticiserProduct name:
CAS Code: 36290-04-7
HS Code (CN): 38244010
SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, , etc…)
SNF is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM Designation 94 as a Type F admixture, GB8076-2008 and G119-2003.
