PDMS-Dimethyl Silicone Fluid in High-Performance Lubrication

19 - Aug - 2025 HENGDA Group

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.


PDMS-Dimethyl Silicone Fluid in High-Performance Lubrication


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.
