Sound Absortion StP Biplast Wave

🟡 StP Biplast 15 Wave (Gold Line Range)

Need a soft, flexible, and high-performance layer to eliminate interior noise and panel squeaks?

StP Biplast 15 Wave is a sound-absorbing, heat-insulating, and anti-vibration material with a unique wave-pattern foam surface that traps sound waves more effectively than flat foam.

It’s perfect for improving acoustic comfort inside any vehicle — from daily drivers to premium builds.

👉 How much do you need?
One pack (7 sheets, 1.3 m² total coverage) is enough to:

• Treat all four doors and the roof, or

• Cover plastic trims, dashboard, and console areas.

👉 Where to use it:

• Doors (inner panels and trims)

• Roof / headliner

• Plastic interior panels

• Dashboard and central console

👉 How to install:

1. Clean the surface (metal or plastic) — free from dust, oil, and residue.

2. Cut the foam to size, peel off the protective film.

3. Press evenly across the surface using light pressure or a roller.

4. Works best at +15 °C or above — if cooler, gently warm with a heat gun for stronger adhesion.

👉 Why it works:

• Open-cell polyurethane foam absorbs sound and prevents squeaks between panels.

• Wave-pattern surface increases sound absorption efficiency.

• Self-adhesive layer makes installation quick and secure.

• Stays flexible in extreme conditions: –40 °C to +100 °C, short-term up to +150 °C.

• Ideal for vibration damping, heat insulation, and acoustic tuning.
