Expanding the Rold of Alumina Fiber in High-Temperature Applications

As manufacturing processes evolve, so too do the demands for materials that can withstand ever-higher temperatures without compromising efficiency or safety. Alumina Fiber has emerged as a standout solution for applications where conventional materials, like silica insulation, fall short. While silica can offer effective insulation at moderate temperatures, it degrades under extreme heat, requiring frequent maintenance and replacements. Alumina Fiber, on the other hand, remains stable and reliable in the most intense thermal environments, significantly reducing maintenance costs and enhancing the longevity of critical components.

This durability makes our Alumina Fiber products ideal for insulating components that operate under high thermal stress.

Leading Applications of Alumina Fiber in High-Temperature Environments

Meeting with industry leaders and experts, we’ve had many meaningful discussions and uncovered their pain points, identifying key areas where our Alumina Fiber products can make a transformative impact. Below are some of the applications of Alumina Fibers that industry leaders are excited about.

Waste Incinerator Erosion Prevention
Our Alumina Fiber woven fabric provides effective insulation in waste incinerators, where it protects refractory ceramic fiber (RCF) modules from erosion. This application extends the lifespan of incinerator components and maintains operational efficiency under harsh conditions.

Insulation for Glass Rollers in Furnaces
The intense heat of glass furnaces requires durable, heat-resistant insulation. Vulcan Shield Global’s Alumina Fiber braided sleeves effectively insulate rollers in these furnaces, protecting the rollers from the heat of the glass, extending the rollers’ service life.

High-Temperature Fabric for Glass Bending
Glass bending applications demand a heat-resistant material on the moulds that won’t degrade or mark glass surfaces. Our F-72 woven Alumina Fiber woven fabric and braided sleeves provide the ideal solution, maintaining high-temperature resistance without leaving any markings on the finished glass products.

Battery Powder Saggars for Lithium-Ion Production
Alumina long fibers are instrumental in the production of saggars for lithium-ion battery powder, enabling saggars to withstand high temperatures without warping or wearing down. This application is critical in battery production, where consistent heat resistance is essential for quality control.

Hybrid Vehicle Insulation
As hybrid vehicles rise in popularity, the need for reliable, lightweight, high-temperature insulation has become essential. Vulcan Shield Global’s Alumina Fiber needled blankets and braided sleeves are used to insulate key components in hybrid vehicles, improving efficiency and safety without adding unnecessary weight.

Insulation in Laser and Plasma Cutting Equipment
Our Alumina Fiber braided sleeves and woven fabric insulate pipes and other components in laser and plasma cutting equipment, protecting them from the high heat generated during cutting. This prevents overheating, extends equipment lifespan, and ensures optimal performance.

Thermocouple Sleeving and Insulation
Thermocouples, used extensively in high-temperature monitoring, require insulation that won’t degrade in extreme heat. Our Alumina Fiber braided sleeves provide essential insulation, ensuring accurate temperature readings and extending thermocouple lifespan.

Furnace Repairs
Furnace components often need resilient insulation to withstand intense heat. Alumina Fiber needled blankets and woven fabric are ideal solutions, offering the durability and temperature resistance required for long-lasting repairs.

Thin Blankets for Catalyst Insulation
Our thin Alumina Fiber needled blankets (3mm) provide lightweight yet effective insulation for catalysts used in processes reaching 900°C. This application is ideal for protecting catalysts without sacrificing thermal efficiency.
