STANDARTPLAST STP BiplastWave / Biplast 10-25 mm / Biplast Profi Car Sound-Absorbing Sheets - 1 Sheet

STP BIPLAST is used as sound-insulating, vibration-damping, heat-insulating, damping, and anti-squeak material in various vehicles.

To protect the mounting layer, anti-adhesive paper or film is used. The surface, opposite to the mounting layer, is taken as a facing surface.

The material remains elastic at the temperature range from -40°C to 100°C, resistant to temperature up to 150°C.

The material is elastic polyurethane foam, mainly, open-cell, with extended recovery time upon the compression cycle cessation.
