NVH Solutions, Gaskets & Seals
Polyurethane (PU) foam plays a vital role in Noise, Vibration, and Harshness (NVH) control in vehicles, as well as in the production of gaskets and seals. Its unique combination of flexibility, durability, and sealing properties helps manufacturers enhance cabin comfort, reduce noise levels, and ensure tight seals in various automotive systems.
Sound Absorption: Open-cell PU foam effectively absorbs and dampens airborne noise from engines, road, and wind, improving cabin quietness.
Vibration Damping: PU foam cushions and isolates vibrations from the drivetrain, suspension, and chassis components to reduce harshness.
Lightweight: Contributes to overall vehicle weight reduction while providing effective NVH performance.
Applications: Used in door panels, dashboards, wheel arches, engine compartments, and firewall insulation.
Sealing Performance: PU foam provides excellent compression and recovery, ensuring airtight and watertight seals in doors, windows, trunks, and HVAC systems.
Flexibility & Durability: Maintains sealing integrity under varying temperatures, pressures, and repeated use.
Custom Profiles: Can be molded or extruded into custom gasket shapes for precise fit and function.
Chemical Resistance: Resistant to oils, fuels, and other automotive fluids, enhancing lifespan.
Benefits of Polyurethane Foam for NVH, Gaskets & Seals
- Excellent resilience and compression set resistance.
- Versatile in density and firmness to suit specific applications.
- Easy to mold and fabricate for complex geometries.
