Krytox™ High-Performance Lubricants For Noise And Vibration Control

Advanced Solutions for Eliminating Automotive Noise and Vibration

Modern vehicles are engineered to provide a smoother, quieter driving experience than ever before. As a result, even minor noises and subtle vibrations—once barely noticeable—are now more apparent and can impact overall driving comfort.

Noise, vibration, and harshness (NVH), along with buzz, squeak, and rattle (BSR), can originate a wide range of internal and external sources. These include interactions such as rubber against painted surfaces, metal against plastic, leather against leather, as well as components within the engine system.

Krytox™ high-performance lubricants are specifically designed to address NVH and BSR challenges. Key advantages include:

• Easy application through spraying or brushing
• Exceptional resistance to harsh environmental conditions such as rain, snow, ice, salt, dust, and dirt
• Strong chemical resistance to fuels, coolants, brake fluids, and washer solvents
• Long-lasting performance without evaporation or degradation over the vehicle’s lifespan
• Excellent compatibility with a wide variety of materials and surfaces

Enhancing Comfort to Meet Modern Driver Expectations

As consumer expectations continue to rise, automotive manufacturers have invested heavily in both passive design improvements and advanced active technologies to minimize NVH and BSR.

Today, noise and vibration performance play a critical role in purchasing decisions—especially with the rapid adoption of electric vehicles (EVs), where the absence of engine noise makes other sounds more noticeable. A quiet and smooth ride is not only a mark of quality but also essential for passenger well-being.

Key impacts of noise and vibration include:

• Low- to mid-frequency noise can significantly increase driver fatigue
• High-frequency noise can interfere with in-vehicle communication
• Persistent noise may lead to stress, headaches, and irritation
• Vibrations can cause discomfort and reduce overall ride quality

Applications of Krytox™ Automotive Lubricants

Krytox™ PFPE lubricants are widely used across automotive systems and can generally be categorized two main application areas:

Under-the-Hood Applications

With increasing demands for compact engine designs and improved fuel efficiency, under-the-hood temperatures are rising—often exceeding 120°C (248°F). This creates a need for high-performance lubricants capable of withstanding extreme conditions.

Typical applications include:

• Alternator decoupler pulleys
• FEAD (Front End Accessory Drive) tensioners and idlers
• Throttle body bearings
• Exhaust gas recirculation (EGR) valves
• Intake manifold seals and actuators
• Fan clutch bearings
• Fuel system emission control valves
• Electric cooling pumps and valves
• Ignition system boots

Interior and Exterior NVH Control

Krytox™ lubricants provide a reliable, long-term solution for eliminating BSR issues both inside and outside the vehicle cabin. These PFPE oils and greases effectively reduce friction-induced noise and mechanical vibrations without causing material compatibility issues or releasing harmful VOCs.

Common applications include:

• Weather stripping and elastomer seals
• Interior surfaces (plastic, metal, leather)
• Console hinges and latching mechanisms
• Door and trunk latch systems
• Brake pedal assemblies
• Seat mechanisms (rails, headrests, latches)
• Electrical switches
• Airbag spring components
• Exterior mirrors
• Suspension bushings
