Exceptional Lubricant for Demanding Applications

Tungsten Disulfide (WS2) effectively reduces friction and wear, making it an ideal solid lubricant for critical equipment and high-temperature operations. Its high mechanical strength and thermal resistance ensure reliability in aerospace, automotive, and industrial scenarios, where conventional lubricants may fail.

Thermal and Chemical Stability

WS2 boasts excellent thermal stability with a melting point around 1250C, and remains chemically inert under normal conditions. This allows for use in challenging environments, while retaining particle integrity and efficacy, especially in high-temperature or corrosive settings.

Fine Particle Size, Maximum Coverage

With particles typically under 1.5 microns, Tungsten Disulfide coats surfaces evenly and penetrates minute spaces in machinery, delivering superior lubrication with a fine, soft-touch surface finish. This enhances both performance and longevity of moving components.

FAQs of Tungsten Disulfide:

Q: How should Tungsten Disulfide powder be stored to maintain its quality?

A: Tungsten Disulfide should be stored in a cool, dry place with the container tightly closed to prevent moisture contamination. When properly stored, the product has an indefinite shelf life.

Q: What are the main benefits of using Tungsten Disulfide as a lubricant?

A: Tungsten Disulfide offers outstanding lubrication, high mechanical strength, excellent dimensional stability, and thermal resistance up to approximately 1250C. It reduces friction and wear, leading to longer equipment life and improved operational efficiency.

Q: Where is Tungsten Disulfide typically applied?

A: Tungsten Disulfide is commonly used as a solid lubricant in bearings, pressing dies, gears, aerospace components, automotive parts, and as an additive in greases and oils for industrial machinery.

Q: What makes Tungsten Disulfide preferable over conventional lubricants?

A: WS2 operates effectively under extreme conditionshigh temperatures, heavy loads, and vacuumwhere conventional lubricants might degrade, providing lasting protection without decomposing or evaporating.

Q: Can Tungsten Disulfide be used in combination with other lubricants?

A: Yes, it is often blended as an additive with oils and greases to enhance lubricity, thermal stability, and wear resistance in both standard and high-performance mechanical systems.

Q: Is Tungsten Disulfide safe and non-toxic for industrial handling?

A: Under normal conditions, Tungsten Disulfide is considered non-toxic and safe for use, provided standard industrial hygiene practices are followed during handling.
