Nychem® XPE 140

Nychem® XPE140 is one of our Medium Nitrile Emulsion offerings.  This line features a combination of excellent 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® XPE140 is a carboxylated butadiene acrylonitrile polymer latex that is stabilized with low/no surfactant so it has high surface tension which gives good resistance to rewetting, good water resistance and low foaming.  It also has good heat and light aging.   Common applications include paper saturation and metal release coatings.
