DiClad® 527 Laminates
- Chemical Family
- Fluoropolymers
DiClad 527 (Er=2.40−2.65) use a higher fiberglass/PTFE ratio to provide mechanical properties approaching conventional substrates. Other advantages include better dimensional stability and lower thermal expansion in all directions. The electrical properties of DiClad 527 are tested at 1MHz and 10GHz, respectively.
