PDMS-dimethyl silicone fluid is widely recognized for its exceptional lubricating properties across extreme temperature ranges (-40°C to 200°C). Its linear polydimethylsiloxane (PDMS) structure provides low viscosity variation (VI >300) and superior film strength, reducing friction coefficients by 30-50% compared to hydrocarbon oils.
Key applications include:
Plastic/rubber lubrication: Prevents cracking in O-rings and seals under dynamic stress
Food-grade machinery: NSF H1-certified formulations ensure safety in processing equipment
Aerospace components: Maintains performance in high-altitude, low-pressure environments
Recent advances include graphene-PDMS nanocomposites that extend relubrication intervals by 400% in industrial bearings.
