Is it worth the risk for businesses to adopt new materials over established manufacturing processes?
Blueshift will demonstrate its PhaseBlue 1500 circuit material at European Microwave Week in London, running from October 4 to 9, 2026. The material is an announced product designed to meet high-performance connectivity demands.
Why it matters
Engineers require materials with lower signal loss and reduced mass to improve signal integrity in high-frequency applications. The introduction of this polyimide-based aerogel addresses both weight and electrical performance constraints simultaneously.
PhaseBlue 1500 features a density of 0.27 to 0.45 g/cm³ and a relative permittivity of 1.3 to 1.5 at 1 GHz. It maintains thermal stability with a glass transition temperature of 305°C and a decomposition temperature of 530°C.
The players
Blueshift
A developer of advanced material platforms specializing in low-density, nanoporous polyimide aerogels for industrial and electrical applications.
The details
The material relies on a nanoporous polyimide aerogel—a synthetic porous ultralight material derived from a gel—comprising 85 percent air and 15 percent polyimide. This structure is engineered for compatibility with standard FR-4 printed circuit board (PCB) manufacturing workflows, including direct imaging, drilling, and etchback processes. It is manufactured without intentionally added per- and polyfluoroalkyl substances (PFAS).

The Tech Race
The development challenges the dominance of standard epoxy-based substrates in high-frequency signal transmission. By leveraging an aerogel architecture, the material positions itself against incumbents that struggle to reconcile low signal loss with ultra-low weight requirements.
Engineers and designers will be able to evaluate the material for high-frequency circuit boards using existing manufacturing infrastructure. Availability for large-scale adoption depends on the company's progress following the October 2026 showcase.
The takeaway
This material signifies a push toward lighter electronic packaging through aerogel technology. Watch for updates on the material's cost-efficiency benchmarks compared to standard laminates during the London conference.
