STP Silver Bitum Bulk Pack Multilayer bituminous vibration-damping material for automotive soundproofing

STP Silver Bitum is a multilayer vibration-damping material designed to reduce vibrations and resonances of metal surfaces in automotive soundproofing treatments.

The structure is composed of:

  • upper layer in non-woven fabric
  • high-density bituminous layer
  • adhesive layer protected by anti-adhesive film

It is a solution designed for entry-level treatments and basic soundproofing interventions, where it is necessary to improve acoustic comfort with a material that is simple to install and cost-effective.

How it works and what it is for

Metal surfaces on the vehicle tend to vibrate and amplify noise while driving. STP Silver Bitum acts:

  • increasing the mass of the sheet metal
  • damping part of the structural vibrations
  • reducing metal resonances
  • improving the rigidity of treated surfaces

The multilayer structure also contributes to:

  • improving material stability
  • increasing surface resistance
  • facilitating installation on curved surfaces

The result is:

  • reduction of structural noise
  • lower body vibrations
  • better overall acoustic comfort
  • When to use it and where to apply it

Main applications:

  • doors
  • floor pan
  • trunk
  • side panels
  • internal metal surfaces

It is suitable for:

  • basic vehicle soundproofing
  • reduction of sheet metal vibrations
  • economical entry-level treatments

Can be used as a first layer in multilayer systems. The material can also be applied to curved surfaces with a minimum radius of curvature of 100 mm.

How many sheets are needed and how to apply it

The quantity required varies depending on the surface to be treated and the desired coverage level. Installation:

  1. thoroughly clean the surface
  2. make sure it is dry
  3. cut the material to size
  4. remove the protective film
  5. apply to the sheet metal
  6. press with a roller to improve adhesion

For correct application:

  • avoid air bubbles
  • work on clean surfaces
  • apply with uniform pressure

STP Silver Bitum is a bituminous vibration-damping material designed to improve vehicle acoustic comfort by reducing vibrations and resonances of metal surfaces.

Thanks to the multilayer structure and ease of installation, it represents an effective solution for basic automotive soundproofing treatments and entry-level interventions aimed at reducing structural noise.
