Tungsten Disulfide - Inorganic Fullerene | NanoSlick Lubricants

NanoSlick Tungsten WS2 particlesThe ultimate lube is the Inorganic Fullerene (IF), like Tungsten Disulfide. “W” is the correct abbreviation for Tungsten (Wolfram originally). WS2 is the most lubricious material available. This material alone would provide better lubrication than MoDS2.

Generally moly is not really nano sized. Nano particles need to be less than 100 nanometers. The (normally) larger moly particles can be filtered out of the oil by the oil filters. WS2 can come in most any particle size. At least as large as 1000 nm. They can also be nano sized. But the IF makes a huge difference.

The “F” says that the the WS2 is in a Fullerene like structure. The “I” says it is not organic (e.g., not carbon). The process and inherent structure puts these particles at less than 100 nm. Truly nano particles. There are several major effects associated with the materials of this size. The simplest and the one that is the basis of the utility of this material; it is so far the most slippery material on earth. Next is the size. The small size enables attraction and bonding processes that appear only at these particle sizes. You get some of this effect in materials (e.g., non-nano moly) but they are much stronger under 100 nm.

But, there is more. The non-IF particles are a superb lubricant, but the process of allowing atomic forces to bond the material so tightly to the surfaces that they make serious effects of filling in the molecular sized peaks and valleys in the surfaces of the materials being lubricated is a function of particle size. The IF particles are constructed rather like an onion (a really really teeny tiny onion). When they are placed between surfaces under some pressure (e.g., bearings) they adhere to a surface and peel off parts of their structure which greatly enhances the filling of surface voids.

Our nano-sized Tungsten Disulfide is so small in particle size that you could place about one thousand of these nanoparticles across the width of a single human hair.
