Matrix Dispersions

Solid lubricants are used in many applications and processes. The Matrix D-Max range contains dispersions based on Graphite, MoS2 (Molybdenum Disulfide), PTFE, hBN (hexanol Boron Nitride). Please contact us to learn more about the use and possibilities of these solid lubricants

The coupled effects of environmental composition,

Liquid lubricants are precluded in an exceedingly large number of consumer as well as extreme applications as a means to reduce friction and wear at the sliding interface of two bodies. The extraterrestrial environment is one such example of an extreme environment which has motivated the development of advanced solid lubricant materials. Mechanical systems for space require fabrication

Greatly improved mechanical and thermal properties of

In this work, molybdenum disulfide (MoS2) nanosheets were employed to enhance the mechanical and thermal properties of chitosan (CS), which was one of the most promising biomaterials. In order to promote a homogeneous dispersion of MoS2 and improved interface interactions between CS and fillers, carboxyl functionalization was subjected to the exfoliated MoS2 nanosheets by chemical conjugation

Tribological performances of graphite–MoS2 coating at

The graphite–MoS 2 coating with 20 wt% graphite addition exhibits the relatively small coefficient of friction and wear scar width at 200 . At or beyond 400, the coating's lubricating effect is severely deteriorated with the testing time.

Solid lubricants: Ceramic oil additive

Solid lubricants: Ceramic additive (hBN) February 8, 2018 8:00 am In our last article we compared MoS2, Teflon and graphite as solid lubricants. Now it's time to talk about the cream of the crop: ceramic (boron nitride). Also called "white graphite", the ceramic

Frontiers

Subsequently, the all-solid-state section will discuss the use of MoS 2 as an effective interface for solid-based electrolytes (e.g., sulfide or garnet-type). Lastly, we provide guidelines on the design and propose testing methodologies to assess the performance of the MoS 2 for high-energy-density Li metal batteries.

Dry lubricant

Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium.[1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil

Applications of carbon quantum dots in lubricant additives:

Advances in lubricants are vital to the pursuit of energy efficiency and sustainable development. It is well known that the essence of lubricating oil is lubricant additives, especially the friction-reducing and anti-wear additives. Carbon quantum dots (CQDs), a novel zero-dimensional carbon-based nanomaterial, have attained growing expectations in material and chemical sciences because of

Tribological properties of solid lubricants (graphite, Sb2S3,

The effect of three different solid lubricants (graphite, Sb 2 S 3, and MoS 2) in the brake friction material on various aspects of friction characteristics was investigated.Three friction material specimens were produced based on an experimental formulation, and they

Innovation in Nanoparticle Additives for Water

Solid based lubricants include, but are not limited to, graphite, WS2 and MoS2 powders/coatings. Oil-based greases are a good example of a semi-solid lubricant. A liquid lubricant with typically 90 percent oil and up to 10 percent additives serves for reduced friction and wear, and resistance to corrosion whereas nitrogen and helium are the typical gaseous lubricants.

Molybdenum Disulfide (MoS2) Powder

Crystal structure is Hexagonal Lamellar and is similar to graphite, Boron Nitride and Tungsten Disulfide. It also has excellent film forming properties and is an excellent lubricant in moisture free environments below 400 C. MoS 2 offers excellent lubricity properties in inert atmospheres and under high vacuum where other conventional lubricants fail.

Additives for Lubricants and Mold Release – BYK

BYK offers different additives for industrial lubricants. Our defoamers can be used to prevent foam generation, and to release air from the lubricant. BYK wetting and dispersing additives can be used to suspend solid additives (e.g. graphite, MoS2). Higher solid

Synthetic Fabrication of Nanoscale MoS2

Hinnemann et al. found that MoS2 nanoparticles supported on graphite were a new class of electrode materials and promising catalyst for electrochemical hydrogen evolution at a moderate overpotential [100], using the criterion where the binding free energy of

Application of solid lubricating molybdenum disulfide

The solid lubricant can be firmly bonded to the surface of the substrate by using the bonded solid lubricating film, thereby effectively preventing the adhesion of the metal parts. It can achieve effective lubrication in special environments where conventional grease is not suitable for use, so it is widely used in environments such as vacuum, high and low temperature, inflammable and
