LEADING ABSORPTION TECHNOLOGY

SPECIFICALLY SUITED FOR NHV

Structural advantage of natural cellulose for efficient absorption

    • made of regenerated cellulose from wood pulp + cotton
    • Self-supported by cellulose structure
    • no melt layer
    • no chemical binder
    • no added source of VOC or aldehydes

    No chemical binder

    • Bicomponent PET has a low-melt copolyester layer
    • PU is isocyanate-based > higher baseline emissions
    • Kalle leads across VOC tests

    Vs synthetic materials

    • Natural origin
    • No harmful emissions
    • Matching NEV cabin-air-quality
    • meets ESG procurement requirements

    Healthy-cabin compliant

At the same installed thickness, Kalle gives better mid-high reduction; conversely, less material is needed for the same absorption.

­ Measured lead

Across 800–3150 Hz, measured peak absorption is ~15–20% above glass wool/PU (equal 5 mm).

­ Same effect, thinner

For the same mid-high absorption, Kalle needs less thickness — good for packaging and light-weighting.

­ Far lighter than glass wool

At 5 mm, density is only 53% of glass wool (668 vs 1254 g/m²) — lighter and stronger mid-high freq.
