Polycrystalline alumina fiber

Product parameter

Polycrystalline alumina fiber
Product classification:
The total content of polycrystalline alumina fiber cotton AL2O3 is about 97%, among which ALPHA AL2O3:>70%, ultimate temperature resistance: 1800 ℃, fiber diameter: 2-4 μ M
Application scope:
1. High temperature insulation for military research, aerospace, nuclear industry, etc
2. Thermal insulation enhancement additives for the automotive lithium battery industry
3. Other high-temperature insulation fields
5. Raw materials for high-temperature resistant products
6. High temperature ceramic insulation and heat-resistant additive
Product features:
1. Polycrystalline alumina fiberboard is a high-temperature resistant and ultra lightweight insulation material. Maintaining a polycrystalline microcrystalline structure at high temperatures ensures good heat resistance and high strength.
2. Low heat storage capacity and excellent heat shock resistance
3. Low thermal conductivity and high temperature stability
4. Good processability, It can be used as a raw material additive to make ceramic fiber paper, board, blanket, felt, etc., significantly improving the high-temperature resistance of ceramic fibers.
Appearance:
For the convenience of transportation, vacuum adsorption is used to form a cloud like (5Kg/box), which can be gently tapped to form loose sand particles during use.
