Absorbing Foams
TUFCOTE®, acoustical absorbing foams are widely used to reduce noise levels within a given space -from equipment cabinetry to vehicle cabs. These tough urethane foams are easily cut and installed, and are available with a variety of protective facings, in thicknesses ranging from 0.25_inch to 2_inches, to match the environmental needs of most any application.
Features
- Economical, functional sound absorption.
- Available in sheets, rolls or easily installed custom die-cut forms.
- Available in composite form with TUFCOTE® barriers and with pressure-sensitive adhesive(PSA) backing.
- The date listed in this materials summary are typical or average values or engineering estimates based on tests conducted by independent laboratories or by the manufacturer.
