High-Temp Flexible Inorganic Fiber Paper

Product Description:

SUNTHERM High-Temp Flexible Inorganic Fiber Paper is made from high-quality alumina-silica fibers via the advanced sol-gel method. Combining material science with precision papermaking, it delivers excellent overall performance. As a purely inorganic material, it offers good flexibility, easy processability, and outstanding heat resistance for long-term use in extreme high temperatures.

Its microfiber structure forms an interconnected network that effectively reduces heat conduction and convection, providing a strong thermal barrier and minimizing heat loss. Being inherently non-combustible, it also offers top-tier flame retardancy, isolating flames and enhancing safety for equipment and operating environments.

Moreover, SUNTHERM High-Temp Flexible Inorganic Fiber Paper maintains exceptional structural stability at high temperatures-no pulverization, shrinkage, cracking, or disintegration. This ensures long-term reliable operation and durable protection in harsh applications such as aerospace, industrial furnaces, and new energy vehicles.

 

Product Features:

Excellent thermal stability: Can be used continuously at temperatures up to 1300°C without structural disintegration or pulverization after high-temperature exposure.

Completely smokeless, non-toxic, and flame-retardant.

Acid and alkali resistance: Exhibits exceptional resistance to all chemicals except hydrofluoric acid, phosphoric acid, and strong alkalis.

FAQ:

Q1: What are the main components of SUNTHERM IOWOOL flexible inorganic paper?

A1: It is made of polycrystalline alumina-silica (Al₂O₃-SiO₂) fibers produced via the sol-gel method, classifying it as an alumina-silica inorganic material.

 

Q2: Does the product degrade or lose strength at high temperatures?

A2: No, it maintains structural integrity even under high-temperature conditions, with no loss of strength, structural disintegration, or pulverization.

 

Q3: In which high-temperature or extreme environments is it suitable?

A3: It is suitable for applications requiring long-term high-temperature resistance, thermal insulation, and structural stability, such as industrial furnace linings, high-temperature pipe insulation, thermal protection for batteries, and aerospace insulation components.

 

Q4: How does the sol-gel manufacturing process benefit the fiber quality?

A4:The sol-gel process produces fibers with high purity and uniform microstructure. This results in a more consistent crystalline phase (typically mullite), which enhances the material's refractoriness, creep resistance, and dimensional stability at elevated temperatures.

 

Q5: Can this paper be used in contact with metals or other materials without causing corrosion?

A5: Yes, due to its high chemical stability and low content of impurities (such as fluxes), SUNTHERM IOWOOL paper is non-corrosive and safe for use in contact with most metals and dissimilar materials, provided the temperature limits are respected.

 

Q6: Is the material resistant to thermal shock?

A6: Absolutely. The fibrous structure and high porosity of the paper provide excellent thermal shock resistance, allowing it to withstand rapid heating and cooling cycles without cracking or spalling.
