Barrier Composites
TUFCOTE®, barrier and barrier composites incorporate the sound absorption properties of TUFCOTE® acoustical foams with the sound barrier properties of TUFCOTE® barrier materials to provide highly effective noise control and installation efficiency in a wide range of applications.
Easy and economical to install, barrier absorber composites are ideal for lining vehicle and boat engine compartments, generator covers, engine firewalls, and machinery and equipment enclosures, where the durable facings provide protection from dirt, oil and grease.
Available with pressure-sensitive adhesive(PSA), they also can be edge-sealed to resist moisture, oil and other contaminants, and easily die-cut.
Features
- Combine tough, flexible E-A-R barriers with acoustical foams for high transmission loss performance.
- E Series composites include WB Series vinyl barriers
- R Series composites include R Series urethane barriers
- Ideal for application to engine firewalls, vehicle floormats, exsiting cabinets and machinery housings.
- Data presented for four products of the many standard and custom composites available.
