Blueshift's PhaseBlue 1500 is the first product in its new Series Circuit Materials line. Engineered with a proprietary nanoporous polyimide aerogel core made of 85% air and 15% polyimide, the laminates combine lightweight flexibility with high-frequency performance for next-generation PCB applications. Designed as a US-made, environmentally compliant alternative to PTFE-based substrates, formulated without intentionally added PFAS. It delivers a dielectric constant of 1.3–1.5 at 1 GHz and an ultra-low dissipation factor below 0.001 at 1 GHz, while maintaining stable performance across 1–10 GHz without the dielectric knee common to conventional perfluorinated systems.

The material offers thermal stability with a Tg of 305 °C and decomposition temperature of 530 °C. Weighing up to 80% less than traditional laminates, PhaseBlue® has a density of 0.27–0.45 g/cm³ and is available in dielectric thicknesses from 0.0065–0.030 inches. Its thin, formable profile makes it well suited for 3D structures, phased arrays, radomes, CubeSats, UAVs and aerospace communications. PhaseBlue integrates with standard FR-4 PCB processes, reducing barriers to adoption. Blueshift reports successful applications across multilayer antenna boards and advanced defense platforms, highlighting long-term reliability under extreme conditions.
