Foam Glass Testing

Foam glass is an inorganic non-metallic porous material made from raw materials such as crushed glass, fly ash, and perlite, along with foaming agents and foam stabilizers, through processes like high-temperature melting, foaming, and annealing. With the global rise in demand for low-carbon buildings, foam glass, as a zero-carbon building material, is expected to see its market size reach several billions of US dollars by 2025, with a compound annual growth rate exceeding 10%. Foam glass dominates the field of cold insulation materials due to its low-temperature stability, making it particularly suitable for LNG storage tanks, chemical pipelines, and other cryogenic projects.
