Information
✓ Melt-blown Microfiber Structure:
Dense micro-air pockets between ultra-fine fibers deliver superior sound absorption across mid-to-high frequency ranges.

✓ Eco-Friendly Polypropylene (PP) & Polyester (PET) Fiber:
Composed of non-toxic, odorless fibers to minimize harmful emissions and volatile organic compounds.

✓ Ultra-Lightweight Design:
Significantly lighter than conventional nonwovens or felts, maximizing component weight reduction and fuel/energy efficiency.

✓ Water Repellency, Thermal Insulation & Flame Retardancy:
Water repellency
prevents odors, while delivering outstanding thermal barrier properties and self-extinguishing safety.

✓ High-Efficiency Acoustic Absorption:
Achieves exceptional Noise Reduction Coefficient (NRC) values even at reduced thicknesses compared to standard acoustic materials.

✓ Seamless Lamination with Damping & Barrier Sheets:
Easily thermal-bonded or laminated with damping layers and sound barriers to create customized multi-layer NVH solutions.

✓ Outstanding Formability & Workability:
Fully compatible with thermoforming, precision die-cutting, and ultrasonic welding for seamless application onto complex geometries
