What Is Ceramic Fiber with Aluminum Foil Blanket?
Ceramic fiber rope is a high-temperature resistant insulation product braided or twisted from ceramic fiber yarns. To enhance durability and tensile strength, it is reinforced with stainless steel wire, glass fiber filament, or nickel alloy wire.
Compared with traditional sealing materials such as asbestos rope, ceramic fiber rope offers safe, lightweight, and environmentally friendly performance, making it an ideal alternative for industrial sealing and thermal insulation applications.
Key Features of Ceramic Fiber Rope
- 🔥 Excellent Heat Resistance – Continuous working temperature up to 1,260°C (2,300°F) depending on grade.
- 🛡️ Superior Thermal Insulation – Low thermal conductivity ensures reliable sealing and reduces energy loss.
- 💪 Strong & Flexible – Reinforced with stainless steel or glass fiber for enhanced tensile strength.
- 🌱 Asbestos-Free & Eco-Friendly – Safe to use in workplaces, suitable as an asbestos replacement.
- 🛠️ Easy Installation – Can be cut, shaped, or installed without losing strength or flexibility.
Types of Ceramic Fiber Rope
To meet different industrial requirements, ceramic fiber rope is available in several forms:
| Type | Structure | Best For |
| Twisted Rope | Multiple strands twisted together | General sealing & light-duty applications |
| Square Braided Rope | Dense and compact | Heavy-duty gasketing & furnace doors |
| Round Braided Rope | Flexible & resilient | Expansion joints, oven doors, industrial pipe seals |
Applications of Ceramic Fiber Rope
- Ceramic fiber rope is widely used in high-temperature sealing and insulation applications across various industries:
- Furnace door seals & expansion joints
- Boiler gasketing & insulation
- Kiln car sealing systems
- High-temperature pipe & valve insulation
- Industrial ovens, dryers & stoves
- Fireproof sealing in power plants & petrochemical facilities
Ceramic Fiber Rope vs. Traditional Sealing Materials
| Feature | Ceramic Fiber Rope | Asbestos Rope | Glass Fiber Rope |
| Max Service Temp. | Up to 1260°C | 500–600°C | 550–650°C |
| Safety | Non-toxic, asbestos-free | Health risks (asbestos) | Safe but lower temperature limit |
| Durability | Excellent | Moderate | Good |
| Applications | High-temperature sealing & insulation | Outdated | Medium-temp insulation |
- 👉 Conclusion: provides higher safety, better heat resistance, and longer service life than asbestos or glass alternatives.
