Dry film lubricants: long-lasting clean lubrication solutions under extreme working conditions

Dry film lubricant (dry film oil) is a high-performance lubricant made of fluorine solvent, perfluoropolyether oil and polytetrafluoroethylene (PTFE) particles. Its core technology is to form a lubricating film on the surface of the workpiece through solvent evaporation. It has three core advantages: low friction coefficient, wide temperature tolerance (-40℃ to 260℃), and zero pollution. It breaks through the application limitations of traditional grease in high temperature, vacuum, and precision scenes.

1. Working principle

Permeation film formation: By spraying or applying to the surface of metal, plastic, rubber and other substrates, the fluorine solvent quickly penetrates into the microscopic pores. Solvent evaporation: The solvent completely evaporates within 10-30 seconds, and the PTFE particles combine with the fluorine oil to form a dense lubricating film. Dynamic protection: The film layer self-repairs during the friction process, continuously provides anti-friction and anti-wear protection, and repels dust and impurities.

2. Core advantages

Compared with traditional grease or oil, dry film lubricant has the following advantages: 1. Better resistance to high/low temperature: Traditional grease is easy to oxidize or evaporate (such as lithium-based grease) above 150°C, and easy to solidify at low temperature, while dry film lubricant can be used for a long time in the range of -40~260°C. 2. Strong adaptability to complex surfaces: It can penetrate the surfaces of complex workpieces such as threads and micropores to form a uniform film layer. Traditional grease is difficult to cover precision structures and is prone to lubrication blind spots. 3. Clean, environmentally friendly and pollution-free: For example, in a vacuum environment or clean room, liquid lubricants may evaporate or pollute the environment. After the dry film lubricant evaporates, it forms a non-sticky lubricating dry film, without oil leakage, and does not pollute the product. It can also increase the finish of the parts, prevent static electricity and dust, and protect the parts from being clean. 4. Strong chemical stability: Dry film lubricant has extremely strong chemical inertness, strong acid and alkali resistance, corrosion resistance, and good compatibility with metals, plastics and elastomers. Long lubrication life can well reduce maintenance costs and save costs.

3. Typical application scenarios

Precision electronics: mobile phone shafts, SD card holders, connectors, etc., provide low-torque lubrication while preventing short circuits. Optical instruments: camera telescopic lenses, microscope guide rails, ensure smooth movement in a dust-free environment. Automotive manufacturing: USB interfaces, sunroof tracks, wiper bearings, withstand high and low temperature cycles and humidity changes. Food and medicine: filling machinery, surgical instruments, comply with FDA certification, avoid oil pollution. Aerospace: satellite components, engine bearings, adapt to extreme environments such as vacuum and radiation.

4. Brand recommendations

For precision lubrication under extreme conditions, Jialede high-performance dry film lubricant is recommended, which is equivalent to internationally renowned brands such as DRYSVRE, MOLYKOTE, KantoKasei, FUMIO, SANKPL and other models. High-performance fluorine dry lubricant refined from high-lubricating fluorine oil and solid lubricating materials has excellent lubricity, wear resistance, high and low temperature resistance, corrosion resistance, high cleanliness and long life; and has passed the EU ROHS test and certification report, and is used on workpieces with high-precision clean lubrication requirements.

Dry film lubricants are reshaping the boundaries of industrial lubrication with their "one oil for multiple uses" characteristics. Their reliability under extreme working conditions, adaptability to clean production, and significantly reduced life cycle costs make them a strategic choice in the field of high-end manufacturing. In the future, with breakthroughs in materials science, dry film lubrication technology will continue to evolve towards higher load-bearing capacity, lower friction, and wider environmental adaptability.
