STP Bitoplast Tape Self-adhesive sound-absorbing tape for sealing and noise reduction

STP Bitoplast Tape is a self-adhesive sound-absorbing tape designed to reduce noise, light vibrations and acoustic leakage at critical points in the cabin. Made of open-cell polyurethane foam, it combines acoustic absorption capacity and sealing function, making it ideal for finishing installations and improving acoustic comfort. Unlike anti-friction tapes, this material also works on sound wave management and acoustic losses.

How a sound-absorbing tape works

In vehicles, many losses in acoustic quality come from:

  • gaps between panels
  • air passages
  • unsealed couplings
  • light vibrations

STP Bitoplast Tape works on multiple levels:

  • absorbs noise thanks to the open-cell structure
  • seals spaces and air gaps
  • reduces light vibrations
  • limits air passage (and therefore sound)

The result is:

  • reduced perceived noise
  • reduction of local resonances
  • improvement of sound quality

Works both as a sound-absorbing material and as a sealing material.

When to use it and where to apply it

It is ideal at points where you need to absorb and seal.
Main applications:

  • joints between panels
  • couplings between plastics
  • edges of linings
  • areas around speakers
  • cable passages

Typical uses:

  • elimination of small internal noises
  • improvement of acoustic seal on doors
  • reduction of sound dispersion
  • finishing car audio installations

Perfect for completing multilayer treatments.

How to apply it

Recommended procedure:

  1. clean the surface
  2. identify the area to be sealed
  3. cut the tape
  4. apply along edges or critical points
  5. press to ensure adhesion

Can be used:

  • as a gasket
  • as a filler
  • as an absorbent layer

Thanks to the compressible structure:

  • it adapts to surfaces
  • fills spaces
  • maintains elasticity over time

STP Bitoplast Tape is a technical tape designed to improve acoustic comfort by working on gaps, couplings and critical points. Thanks to its open-cell structure and ability to adapt to surfaces, it represents an effective solution for completing soundproofing treatments and achieving a cleaner and more controlled result, especially in car audio installations and finishing work.
