Frequently asked

What temperature can ceramic fiber insulation withstand? +

Ceramic fiber insulation withstands temperatures from 1100°C to 1430°C, depending on the grade. Standard (ST) and High-Purity (HP) grades are rated for 1260°C, while High-Alumina (HA) handles 1360°C and Zirconia (HZ) reaches 1430°C. Always match the grade to your specific operating temperature.

What are the differences between COM, ST, HP, HA, and HZ grades? +

The grades differ mainly in alumina (Al₂O₃) content and temperature rating. COM (1100°C) is the economy grade. ST (1260°C) is the standard industrial grade. HP (1260°C) offers higher purity with lower shot content. HA (1360°C) has higher alumina for superior thermal stability. HZ (1430°C) contains zirconia for the highest temperature resistance.

Is ceramic fiber insulation safe? +

Yes. Our ceramic fiber products are 100% asbestos-free and manufactured to international safety standards. They are classified as non-carcinogenic under EU Directive 97/69/EC. We recommend standard PPE (gloves, dust mask) during handling, as with any fibrous insulation material.

How is ceramic fiber blanket installed? +

Ceramic fiber blanket can be cut to size with a utility knife and secured using high-temperature anchors, pins, or stud welding. For furnace linings, a layered installation is recommended. For pipe insulation, wrap and secure with stainless steel bands. Full installation guidance and technical support are provided with every order.

What are the typical applications for ceramic fiber products? +

Ceramic fiber is widely used in industrial furnaces, kilns, boilers, petrochemical heaters, power generation equipment, incinerators, and building fire protection systems. It is ideal for backup insulation, expansion joints, door seals, and high-temperature gaskets.
