Product Advantage
An engineered coarse-denier bi-component nonwoven base cloth for automotive interiors. Designed as a soft-pack substrate and backing for door panels, headliners, seat backs, trunk liners and pillar trims, it combines low weight with high dimensional stability and clean VOC profile. Suitable for thermoforming, lamination and cut-and-sew processes.
Stiff-yet-light: coarse denier filaments create a stable 3D web that resists sagging in vertical trims.
Clean cabin air: low-VOC resins and controlled processing for modern OEM odor/VOC targets.
EV-ready acoustics: functions as a decoupler layer to reduce structure-borne noise when paired with foams or felts.
Sustainable options: mono-polymer and recyclable blends available to facilitate end-of-life recovery.
Coarse-denier filaments (≥ 15 D) for stiffness and handling.
Tensile (ISO 9073-3): ≥ 150 N/50 mm (MD), ≥ 120 N/50 mm (CD) typical.
Heat shrinkage at 120 °C, 30 min (ISO 5077): ≤ 2–3%.
Basis weight: 80–150 g/m² (custom).
Thickness: 0.6–2.5 mm (tooling-dependent).
Works as a low-mass thermal spacer behind surface skins.
Designed to meet FMVSS 302 / GB 8410 burning rate for interior trims.
VOC/fogging: engineered for VDA 278 / VDA 270 targets（low odor options）.
UV conditioning: retains strength after accelerated exposure (per ISO methods).
Thermoformable, punchable, and compatible with hot-melt lamination & adhesive bonding.
Surface options: smooth / embossed / printable.
Roll format for automated lay-up.

FAQ
Q1: How is this different from needle-punched felt?
This base uses coarse-denier bi-component fibers to raise stiffness at lower basis weight, improving formability and anti-sag for vertical trims.
Q2: Can it meet FMVSS 302 / GB 8410?
Yes—formulations are engineered to pass interior-trim burning-rate requirements when processed to spec.
Q3: Is it recyclable?
Mono-polymer grades (e.g., all-PP) support single-stream recycling; blended bi-component versions are designed for reduced VOCs and long service life.
