Low-Noise Polyester Wire Harness Tape | Automotive Fleece Tape for BSR Reduction | Liantu®
High-performance polyester harness tape designed for cabin silence. Class C noise damping, easy hand-tearable, and heat resistant up to 125°C. The professional choice for dashboard and door panel wiring.
Product Introduction
Liantu Low-Noise Polyester Harness Tape is engineered for the modern automotive interior, where cabin silence is a mark of luxury. Unlike stiff PVC tapes that cause "clicking" sounds against plastic panels, our soft-fleece polyester base absorbs vibrations and eliminates mechanical noise. Combined with a "hand-tear" optimized weave, it allows technicians to wrap complex harnesses 30% faster without needing cutting tools.
Why Liantu Polyester Tape is Different:
Acoustic Damping (Class C): Specifically formulated to dampen frequencies that cause cabin buzz and rattle.
Gentle Flexibility: Maintains the "soft-touch" of the harness, allowing it to bend around tight corners in dashboards and door modules without stress points.
Anti-Aging Stability: Our specialized acrylic adhesive won't become brittle or "gooey" even after years of exposure to interior heat cycles.







Technical Specifications
| Property | Value / Class | Industry Standard | Why it matters |
|---|---|---|---|
| Backing Material | Polyester Fleece / Cloth | -- | Soft, vibration-absorbent base |
| Total Thickness | 0.25mm - 0.30mm | -- | Optimal bulk for sound insulation |
| Noise Damping | Class C ( ≥5 to 1010 dB) | LV 312 | Significant reduction in cabin noise |
| Temperature Range | −40∘C−40∘C to +125∘C | -- | T3 Grade; safe for interior heat |
| Adhesion to Steel | ≥2.5N/cm≥2.5N/cm | -- | Permanent bond; no flagging |
| Tearability | Excellent (By Hand) | -- | No scissors needed; prevents injury |
High-Value Application Scenarios
Automotive Dashboard Wiring: Wrapping instrument cluster and infotainment harnesses to prevent rattles against the plastic housing.
Door Module Harnessing: Protecting window and lock wires from friction and noise within the door cavity.
Roof Liner & Pillar Wiring: Securing airbag and lighting wires where a "soft finish" is required to prevent roof sagging or noise.
Home Appliance Electronics: Used in premium washing machines and refrigerators to dampen wire-on-metal vibration sounds.
The "Expert Corner"
How to Optimize Noise Damping: The "Spiral Wrap" Technique For maximum BSR (Buzz, Squeak, Rattle) protection, we recommend a 50% overlap spiral wrap.
Avoid "Spot Taping": While spot taping saves material, it leaves exposed wire sections that can still strike plastic panels.
Tension Control: Do not over-stretch the polyester tape. Unlike PVC, polyester fleece works best when the fibers are relaxed, as the "loft" of the fabric is what absorbs the sound energy.
The Soft-Touch Finish: Our tape is designed to be "hand-tearable" across the width but extremely strong along the length-ensuring it never snaps during the wrapping process.
FAQ
Q: Is this tape resistant to abrasion?
A: Yes, it meets the Class B Abrasion Resistance standard, making it suitable for areas where the harness might rub against the vehicle frame.
Q: Does the adhesive "bleed" over time?
A: No. We use a high-stability, solvent-free acrylic adhesive that remains stable and non-migratory even at constant temperatures of 105∘C.
Q: Can this be used in the engine compartment?
A: This tape is optimized for Interiors (T2/T3). For high-heat engine areas (150∘C+), we recommend our specialized Heat-Shield Aluminum or High-Temp Cloth ranges.
