Fireproof Ceramic Fiber Paper - High-Temp Heat-Resistant Insulation (0.5mm-5mm Thick) For Industrial & Precision Scenarios

1. Product Overview

This Fireproof Ceramic Fiber Paper is manufactured via advanced wet-laid processes: first, high-purity alumina-silica fibers (3-5μm diameter) are dispersed into a uniform slurry; then, the slurry is laid on a forming mesh to create ultra-thin sheets (controlling thickness via mesh speed); next, vacuum dewatering and low-temperature drying (120℃) remove moisture without damaging fibers; finally, high-temperature calcination (800-1000℃) enhances structural stability and eliminates organic binders. Unlike traditional insulation papers (e.g., glass fiber paper), its inorganic fiber composition ensures non-combustibility (Class A fire rating) and no toxic gas release at high temps. The product is supplied in rolls (width 610/1220mm, length 3600-7200mm) or die-cut gaskets, with moisture-proof packaging (vacuum-sealed plastic + cartons) to avoid fiber absorption of moisture-ensuring consistent insulation performance.

2. Key Features

Ultra-Thin & Flexible: Thickness 0.5mm-5mm (thinnest up to 0.3mm on request), can be bent into curved shapes or cut into complex patterns-perfect for narrow gaps (e.g., between industrial furnace door seals, precision instrument components) where thick insulation materials can't fit.

High-Temp Stability: Working temp up to 1360℃, refractoriness ≥1500℃-withstands long-term use in high-temp equipment (e.g., 1200℃ electric furnace gaskets) without charring, shrinking, or melting.

Efficient Heat Insulation: Thermal conductivity ≤0.08 W/m·K at 350℃-50% lower than glass fiber paper, reducing heat transfer between high-temp parts and ambient environment, protecting sensitive components from thermal damage.

Strong Mechanical Performance: Tensile strength ≥1.5MPa (dry state), tear resistance ≥5N-resists breakage during cutting, installation, and equipment vibration; surface smoothness (Ra ≤2μm) ensures tight fitting with mating parts, no air leakage.

Die-Cut Customization: Supports precision die-cutting into circles, squares, gaskets, or irregular shapes (min. tolerance ±0.1mm) with MOQ 100 pieces-matching specific sizes of equipment components (e.g., sensor gaskets, valve seals).

4. Application Scenarios

Industrial Equipment Seals & Gaskets: Furnace door seals, high-temp valve gaskets, boiler manhole gaskets-1360℃ heat resistance withstands equipment high temps, flexible structure ensures tight sealing, no air leakage.

Precision Instruments & Electronics: Insulation layers for temperature sensors, thermal shields for LED chips, battery pack fireproof separators-ultra-thin design avoids interfering with instrument precision, heat insulation protects sensitive components.

Automotive & Aerospace: Exhaust system gaskets, engine compartment heat shields, aircraft cabin fireproof partitions-lightweight (200-300kg/m³) reduces vehicle/aircraft weight, non-combustibility meets safety standards.

Household Appliances: Electric oven door insulation, microwave oven cavity liners, toaster heat shields-food-grade safety (no toxic release) ensures consumer safety, efficient insulation improves appliance energy efficiency.
