Nychem® 1570X79 Carboxylated Nitrile-Butadiene Latex

Nychem 1570X79 is one of our Medium Nitrile Emulsion offerings. This line features a combination of very good oil, grease and hydrocarbon resistance, toughness/resilience, and tear and abrasion resistance. Toughness, abrasion resistance and chemical resistance can be further enhanced though either vulcanization or by adding external crosslinking agents such as melamines, epoxies, phenolics or metal complexes. Nychem 1570X79 is a highly carboxylated butadiene acrylonitrile polymer latex that is stabilized with synthetic surfactants so it exhibits superior mechanical stability. It is approved for use under FDA regulations 177.2600 (rubber articles). Common applications are nonwoven binders and textile coatings.
