1. Introduction of TLY-5Z
TLY-5Z laminates laminates are advanced, glass-filled, PTFE composites with woven fiberglass reinforcement. The glass-filled structure was designed for low density applications such as aerospace having optimally low weight requirements. This results in a dimensionally stable composite which is otherwise not possible with nonreinforced PTFE. The low density approach also makes for a composite with a low Z axis expansion which is also not otherwise possible with PTFE-rich composites. TLY-5Z is much more thermally stable with respect to Z axis expansion induced stress on plated through holes than conventional low dielectric constant PTFE-composites.
