In high-temperature industrial applications, the service life of insulation materials directly impacts equipment stability, maintenance costs, and overall energy efficiency. As a flexible, high-temperature-resistant insulation filler, ceramic bulk is widely used in furnace gap filling, insulation repair, and the forming of prefabricated components due to its excellent thermal properties and moldability. But how long does ceramic bulk actually last? What factors affect its durability? CCEWOOL® has the answers.
Ceramic bulk refers to loose ceramic fibers made from high-purity alumina and silica through spinning or blowing processes. These fibers are long, fluffy, and soft, offering excellent thermal stability and thermal shock resistance. Ceramic bulk is widely used for furnace sealing, irregular space filling, and as base material for high-temperature molding.
High-quality ceramic bulk generally lasts 5 to 8 years, and in some sealing and filling applications, it can last over 10 years. Its longevity stems from several key properties:
High-Temperature Resistance: With a temperature rating of 1260°C to 1430°C, it maintains its integrity and doesn’t powder or collapse under prolonged heat.
Excellent Thermal Shock Resistance: Remains intact during frequent heating and cooling cycles.
Superior Chemical Stability: Resistant to acids, alkalis, and oxidation, suitable for harsh atmospheres.
Maintainability: Easy to install and replace, allowing partial repairs to extend system life.

In high-temperature industrial operations, thermal stability is the most critical indicator to evaluate whether an insulation material can operate safely over the long term. When furnace temperatures fluctuate from several hundred degrees to over 1200°C, any material that shrinks, powderizes, or collapses will cause heat leakage, lining damage, and unplanned shutdown risks. Therefore, only a […]
