High-Temperature Ceramic Fiber Gasket | 1450°C Direct Flame Contact & Corrosion Resistance
Product Overview
Our ceramic fiber gasket is an industrial-grade, high-temperature sealing solution designed for extreme heat environments up to 1450°C. Engineered for direct flame exposure and superior corrosion resistance, this flexible yet durable gasket delivers reliable performance in demanding applications such as industrial kilns, furnaces, and high-temperature equipment. With low thermal conductivity and minimal heat storage, it ensures energy efficiency and long-term stability under intense thermal cycling.
Key Advantages
-
Extreme Temperature Resistance: Withstands continuous temperatures from 1260°C to 1450°C, depending on material grade (Standard, High-Alumina, Zirconium-containing).
-
Excellent Thermal Insulation: Low thermal conductivity (0.055–0.180 W/m·K) reduces heat loss and improves energy efficiency.
-
Direct Flame Contact Suitable: Ideal for sealing in environments with direct flame exposure.
-
High Compressive Strength: Non-brittle structure ensures durability under mechanical stress and vibration.
-
Customizable Shapes & Sizes: Precision-cut to match customer specifications, including complex geometries.
-
Lightweight & Low Heat Storage: Enhances operational efficiency and safety during handling.
