For over 50 years, King has been a leader in the alkylation of naphthalenes, and today King is the producer of the world’s broadest line of alkylated naphthalene synthetic fluids. Designated the NA-LUBE KR Series, these products are the ideal choice for use as base stocks to meet the industry’s highest performance standards where high temperatures degrade petroleum based products or as modifiers for non-polar base stocks, such as Group II oils, Group III oils, and PAO’s. NA-LUBE KR Series can help formulators meet today’s ever-increasing demands placed on lubricants. This includes three new NSF HX-1 registered products that meet the requirements for incidental food contact as prescribed by FDA 21 CFR 178.3570. NA-LUBE KR alkylated naphthalenes provide superior thermo-oxidative stability, excellent hydrolytic stability, and greater film thickness compared to alternative base fluids. They are available in a viscosity range of 4 to 20 mm²/s @ 100°C.
