Molykote EM-50L is a high-viscosity synthetic silicone grease formulated for smooth sliding of plastic and metal components in cleanroom-level environments. It provides a soft, consistent operating feel, reduces mechanical noise in motion systems, and maintains long-term lubrication stability in devices requiring low contamination and quiet performance.

• Temp Range - Molykote® EM-50L delivers stable lubrication from −40°C to 150°C, supported by its base oil viscosity of 1,050 mm²/s at 40°C. This broad span allows the grease to maintain film integrity in both cold-start conditions and moderate operating heat, preventing torque fluctuation in sliding components.

  
  

• Oxidation Resist - Heat-aging tests show limited viscosity growth and low formation of oxidative byproducts, indicating strong resistance to degradation. This stability reduces the frequency of relubrication and keeps sliding resistance consistent during extended operational cycles.

  
  

• Water Resist - Moisture-exposure evaluations confirm that the grease retains lubricity in humid and splash-prone environments. Its formulation prevents rapid wash-off and maintains separation between moving surfaces, helping reduce wear in assemblies exposed to condensation.

  
  

• Plastic Compat - Compatibility testing with thermoplastics such as POM, PA, PC and ABS demonstrates low swelling and chemical stability. This makes EM-50L suitable for sensitive interfaces where plastic dimensional accuracy and long-term smooth sliding are required.

  
  

• Low Volatile - Weight-loss measurements under elevated temperatures show low evaporation rates. This helps maintain grease volume in confined housings, minimizes deposit formation and supports long service life in enclosed motion systems.

  
  

• Noise Reduction - Mechanical noise tests show reduced stick–slip and smoother sliding due to the grease’s high viscosity and stable film formation. This contributes to quieter operation in devices where acoustic performance is critical, such as cleanroom equipment and consumer precision products.

• Automotive - Molykote® EM-50L is suitable for automotive interior mechanisms requiring stable sliding performance, such as in-console gears, seat track guides, HVAC damper controls and switch modules. Its ability to maintain consistent motion feel under vibration and fluctuating temperatures makes it ideal for components that operate frequently in compact cabin environments.

  
  

• Electrical Appliances - Molykote® EM-50L is widely used in small and mid-size appliances where smooth sliding and controlled operating force are critical. It supports stable motion in levers, rotary selectors, dampers and actuator rails. Its clean operation helps reduce mechanical noise inside appliances exposed to repeated daily use.

  
  

• Precision Instruments - Molykote® EM-50L serves well in devices that require precise, low-friction movement, such as optical alignment mechanisms, micro-adjustment sliders and measurement equipment. The grease’s stable viscosity helps preserve delicate positioning accuracy and ensures repeatable motion in sensitive instrument assemblies.

  
  

• Consumer Electronics - Molykote® EM-50L is suitable for noise-sensitive sliding interfaces commonly found in electronics, including camera modules, guide rails, loading trays, hinge systems and compact motor-driven mechanisms. Its clean lubrication helps maintain a smooth tactile feel and reduces wear in high-frequency actuation components.

  
  

• Office Equipment - Molykote® EM-50L performs reliably in printers, copiers and document-handling systems where controlled sliding, reduced friction and long-term lubrication stability are required. It supports mechanisms such as cams, gears, clutches and guide frames to ensure consistent paper movement and quieter operation.
