This high-temperature fiberglass sealing sleeve is woven from industrial-grade fiberglass yarn. It is an asbestos-free, safe and environmentally friendly high-performance alternative designed for sealing and insulation needs in extreme temperature environments. Suitable for thermal systems such as boilers, chimneys, heat exchangers, etc., with long-term operating temperatures up to 550°C, and has excellent sealing, insulation and mechanical strength.

High temperature protection, strong performance
Continuous temperature resistance up to 550°C: suitable for long-term heat exposure conditions such as boiler walls, hot pipes, etc.
High tensile strength (1.5 MPa): has good pressure bearing and deformation resistance.
Tear strength of 50 N/mm: cope with frequent vibration, stretching and installation adjustments, long service life.

Asbestos-free design, green and environmentally friendly
Non-toxic and asbestos-free: a safer industrial sealing solution.
Class A non-combustible material: self-extinguishing flame retardant, improve on-site safety factor.
Excellent insulation: effectively prevent leakage, suitable for electrical environments.

Durable and stable, suitable for harsh environments
Chemical corrosion resistance: resistant to acids, alkalis, oils, water vapor and other chemicals.
UV and ozone aging resistance: suitable for outdoor or strong light exposure conditions.
Low shrinkage and no deformation: the structure remains intact after long-term use to avoid sagging and loosening.

Wide range of applications: ideal choice for boiler sealing, exhaust system, cable protection, thermal energy system coating and other scenarios.
