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.Whether working to develop an innovative new product or to improve an existing product, the NA-LUBE KR Series can help formulators meet today’s ever-increasing demands placed on lubricants. Including those of meeting the requirements for incidental food contact as prescribed by FDA CFR 178.3570 with three new NSF HX-1 registered products, KR-006FG, KR-015 FG and KR-029 FG.
NA-LUBE KR alkylated naphthalenes provide superior thermo-oxidative stability, excellent hydrolytic stability, and greater film thickness compared to alternative base fluids. In addition, the non-polar nature of the NA-LUBE KR products makes them superior to other synthetic fluids in that there is no surface competition with additives.
