Taconic has over 35 years of experience coating fiberglass fabric with PTFE (polytetrafluoroethylene). This enables Taconic to manufacture copper clad PTFE/woven glass laminates with exceptionally well controlled electrical and mechanical properties.
These attributes effectively extend the usefulness of these laminates to X-Band and above.
The dielectric constant (Dk) range is 2.45 to 2.65. The Dk can be specified anywhere within this range with a tolerance of ± .05. The dissipation factor is approximately .0006 when measured @ 1 MHz.

TLT laminates can be sheared, drilled, milled, and plated using standard methods for PTFE/woven fiberglass materials. The laminates are dimensionally stable, and exhibit virtually no moisture absorption during fabrication processes.
TLT laminates are generally ordered clad on one or both sides with 1/2, 1, or 2 oz. electrodeposited copper foil. Contact our Customer Service Department for alternate claddings.
Typical applications for TLT laminates include radar systems, phased array antennas, mobile communication systems, microwave test equipment, microwave transmission devices and RF components.
The copper-clad laminates meet the latest revision of IPC-L-125.
TLT laminates are tested in accordance with IPC-TM-650. A Certificate of Compliance containing actual test data accompanies each shipment.
