In high-temperature industrial applications, the insulation system of furnaces and heat-treatment equipment requires not only low thermal conductivity but also sufficient mechanical strength and durability. Traditional ceramic fiber blankets tend to loosen or shed fibers after long-term exposure to hot gas flow and equipment vibration, which compromises insulation stability.

CCEWOOL insulation ceramic fiber blanket stands out with excellent tensile strength and structural stability. Even under high temperatures, it maintains fiber integrity and density, resisting powdering and collapse, thus ensuring long-lasting and reliable insulation performance.

High-Purity Spun Fiber + Double-Sided Needling: Ensuring Superior Strength

The strength of CCEWOOL insulation ceramic fiber blanket comes from strict control of raw materials and production processes:

High-Purity Spun Ceramic Fiber

Made from in-house melted, high-purity raw materials, spun in an electric furnace. The fibers are long and low in shot content, providing greater toughness and heat resistance.

Double-Sided Needling Technology

The blanket undergoes uniform needling on both sides, tightly interweaving the fibers. This significantly increases tensile strength and erosion resistance, preventing delamination or fiber loss even during long-term operation under hot gas flow.

Automated Forming and Intelligent Temperature Control

Fully automated layering and intelligent temperature control ensure uniform fiber distribution and density, preventing localized weakness and uneven thickness, resulting in more consistent physical and thermal properties.

Applications in Furnace Linings: Longer Service Life and Lower Costs

With its high strength and flexibility, CCEWOOL insulation ceramic fiber blanket performs exceptionally well in furnace linings and insulation layers. It not only reduces furnace shell temperature and minimizes heat loss but also withstands thermal shock caused by frequent heating and cooling cycles. This significantly extends the life of furnace linings and reduces maintenance frequency and operational costs.
