In high-temperature industrial equipment, industrial furnaces, and various thermal insulation systems, ceramic fiber blanket is widely used for its lightweight structure, high insulation efficiency, and installation flexibility. During product selection, one of the most common questions users ask is: What temperature can a ceramic fiber blanket withstand?

In fact, a ceramic fiber blanket does not have a single fixed temperature rating. Depending on raw materials, chemical composition, and manufacturing process, ceramic fiber blankets are available in different temperature grades. The following section explains the common temperature classifications based on practical industrial applications.

Common Temperature Grades of Ceramic Fiber Blanket

In industrial use, ceramic fiber blanket is generally available in the following temperature grades:

1100°C grade: Suitable for medium-temperature industrial equipment, pipelines, and backup insulation layers where basic thermal insulation is required.

1260°C grade: One of the most widely used temperature grades in industrial furnaces, offering a balance between performance stability and cost efficiency.

1400°C grade: Designed for higher-temperature applications, where improved thermal stability and structural integrity are required.

1430°C grade: A high-end temperature classification, typically used in systems operating close to or continuously at high-temperature limits.

It is important to note that the classification temperature does not represent the long-term service temperature. Instead, it indicates the maximum temperature the product can withstand under defined conditions and is used as a guideline for material selection and safety margins.

A Premium Choice in Ceramic Fiber — CCEWOOL PUREWOOL Ceramic Fiber Blanket

CCEWOOL PUREWOOL Ceramic Fiber Blanket is available in 1260°C and 1430°C grades and represents a premium level within ceramic fiber insulation. In standard industrial applications, PUREWOOL reflects the mature performance of high-purity ceramic fiber blankets.

The PUREWOOL series is manufactured using a high-purity synthetic raw material system with strictly controlled impurity levels. Extremely low impurity content not only results in a cleaner, whiter fiber appearance but also effectively reduces the risk of grain crystallization, thereby minimizing linear shrinkage and long-term structural degradation.

Combined with proprietary spinning technology and an in-house developed double-sided internal needle-punching process, CCEWOOL PUREWOOL Ceramic Fiber Blanket consistently achieves tensile strength above 85 kPa. This ensures the fiber structure remains intact during installation, thermal cycling, and long-term operation, delivering improved resistance to thermal shock.

In practical applications, PUREWOOL ceramic fiber blanket offers the following advantages:

Classification temperature up to 1430°C

Lower linear shrinkage at high temperatures with excellent structural retention

Enhanced thermal shock resistance for frequent temperature cycling

Superior insulation performance that extends overall furnace lining life

Widely used in reheating furnaces, soaking furnaces, walking beam furnaces, and other typical industrial furnace types

For customers who prioritize stability, service life, and consistent quality, CCEWOOL PUREWOOL Ceramic Fiber Blanket represents a higher-standard ceramic fiber insulation solution.

How to Select the Right Temperature Grade of Ceramic Fiber Blanket

When selecting a ceramic fiber blanket, it is not sufficient to focus only on the maximum temperature rating. A comprehensive evaluation should include:

Actual long-term operating temperature

Frequency and amplitude of thermal cycling

Installation position (hot face or backup insulation)

Requirements for service life and maintenance intervals

For most industrial furnaces and continuous-operation equipment, 1260°C PUREWOOL Ceramic Fiber Blanket is sufficient for stable long-term performance. In higher-temperature or more demanding conditions, 1430°C PUREWOOL Ceramic Fiber Blanket provides additional safety margins and enhanced performance reliability.

CCEWOOL PUREWOOL Ceramic Fiber Blanket, based on a high-purity synthetic raw material system and combined with excellent tensile strength, thermal shock resistance, and insulation performance, covers the two key temperature grades of 1260°C and 1430°C, representing a premium ceramic fiber solution.

Whether applied in standard industrial high-temperature systems or in applications approaching temperature limits, CCEWOOL PUREWOOL ceramic fiber blanket delivers stable long-term performance and reliable service life, providing a predictable and sustainable insulation solution for high-temperature systems.
