The GJN nano-microporous composite thermal insulation material adopts a proprietary innovative nano-composite process. Through precise regulation of the interfacial bonding between silica aerogel and high-performance fibers, it constructs a gradient microporous insulation structure that perfectly integrates ultra-low thermal conductivity (with room-temperature thermal conductivity comparable to traditional materials) and high mechanical strength (tensile strength ≥70 MPa).Specifically designed for harsh industrial environments involving high temperatures, vibration, and corrosion, it delivers 30%~50% higher comprehensive energy efficiency compared to traditional aluminum silicate materials, providing long-lasting and stable thermal insulation protection.
Hybrid silica‑aerogel / high‑performance‑fibre blanket engineered for full‑temperature industrial insulation where high mechanical strength and chemical resistance are critical.
