1600C Polycrystalline Alumina Fiber Bulk

Product Description:

SUNTHERM ALWOOL 95-N 1600C polycrystalline alumina fiber bulk is a high-performance polycrystalline alumina fiber specifically designed for industrial insulation applications. Composed primarily of alumina and silica, this advanced material is manufactured using the internationally recognized "sol-gel" process, which ensures superior purity and structural uniformity.

As one of the next-generation ultra-lightweight high-temperature insulation materials currently available, SUNTHERM ALWOOL 95-N features a pristine white appearance, a smooth surface, and a soft, elastic texture. Compared to the AL72-M polycrystalline alumina fiber, it offers a significantly higher operating temperature, making it suitable for more demanding thermal environments.

In addition to its excellent thermal stability, the fiber can be readily processed into various forms, including fiber boards and custom-shaped fiber components. These versatile properties make it an ideal choice for a wide range of applications, such as high-temperature insulation systems, aerospace components, and other advanced technical fields requiring reliable performance under extreme heat.

Product Features:

Excellent high and low-temperature resistance, with an operating range of 1400°C to 1800°C;

Superior resistance to acids and alkalis;

Fiber is free of shot balls (≥45μm); lower shot content results in better thermal insulation and refractory performance;

Excellent electrical insulation properties;

High design flexibility; products with varying properties can be obtained by adjusting chemical composition and heat treatment processes.

Product Applications:

Aerospace thermal protection systems

High-temperature furnace linings / insulation panels

Rocket engine insulation layers

Lining for molten metal transfer ladles

Insulation cylinders for photovoltaic crystal growth furnaces
