Amid growing demands for industrial high-temperature insulation and energy efficiency, aluminum foil fiber blankets are gaining increased attention for their versatile performance. What makes them excel in areas such as thermal insulation, sound absorption, and corrosion resistance?
Aluminum foil fiber blankets typically consist of a base layer made from ceramic or glass fiber blanket, coated with a highly reflective aluminum foil surface. This design not only provides excellent high-temperature insulation but also reflects infrared radiation, effectively "bouncing" heat back to its source (blog.okorder.com), significantly reducing heat transfer.
In addition to offering thermal and fire resistance, the aluminum foil layer also delivers moisture and corrosion protection, preventing the underlying fibers from absorbing humidity. The fiber material itself offers high heat resistance, chemical stability, and thermal shock resistance, ensuring long-term reliability.
Mechanically, the aluminum foil composite structure enhances tear resistance and overall strength. For example, products designed for pipeline insulation and duct wrapping have a density of approximately 96 kg/m³, can withstand temperatures up to 1260°C, and offer a tensile strength of 5.36 kg/cm² and tear strength of about 0.3 kg-fully meeting industrial requirements (njmkt.net).
