We don't sell experiments,
we sell verified results.

Lab-validated

The GeoPolyRage matrix (density 2600–2900 kg/m³, specific heat capacity 1.6–1.8 kJ/(kg·K)) has been physically tested. Operating temperature is 550°C; test specimens withstand up to 1100°C without deformation.

A-Nodes Thermal Simulation

Before casting, we simulate the customer's integration dynamic response and discharge rate. No surprises — only verified results.

Lifecycle · Sustainability

Circular Economy 2.0 & End of Life

Manufacturing

Zero-Emission Origin

100% from industrial side streams (fly ash, slag). No sintering in furnaces. Lower carbon footprint and support for VnA 604/2020 criteria.

Decommissioning

Avoiding the Lithium Trap

No expensive dismantling or hazardous waste. After decades, the fully inert and non-flammable matrix is crushed for reuse in civil engineering.
