Taconic TLX-9 DK2.50 Df0.0019 (0.13-3.18mm+) PTFE/Woven Glass Laminate
Brief Introduction
Taconic TLX laminates are PTFE/woven glass copper-clad laminates manufactured with over 35 years of coating experience. TLX-9 features a dielectric constant of 2.50 ±0.04 and dissipation factor of 0.0019 at 10 GHz. These materials offer exceptionally well-controlled electrical and mechanical properties, with excellent dimensional stability and virtually no moisture absorption during fabrication.
