Release Time: 2025-12-17

What is the difference between high-purity ceramic fiber blanket and ordinary ceramic fiber blanket? As the name suggests, high-purity ceramic fiber blankets have higher purity than ordinary ceramic fiber blankets. The main differences between high-purity ceramic fiber blankets and ordinary ceramic fiber blankets are raw material purity, production process, temperature resistance, mechanical strength, and application scenarios; In terms of price, high-purity models have higher costs due to complex processes, while standard models are more economical.

Difference in parameters between high-purity ceramic fiber blanket and ordinary ceramic fiber blanket:

Application fields of high-purity ceramic fiber blanket and ordinary ceramic fiber blanket:

Pure needle punched blankets are mainly used in fields that require high material purity, high temperature resistance, and thermal insulation performance. For example, in the aerospace field, the insulation system used for aircraft, such as the insulation protection around the engine, can withstand the high temperature during engine operation and reduce the weight of the aircraft. In high-end industrial furnaces, such as those producing monocrystalline silicon, it can provide a stable high-temperature environment to ensure production purity.

The standard needle punched blanket has a wider range of applications and is more common. In the construction industry, insulation used for buildings can reduce indoor and outdoor heat exchange and play an energy-saving role. In terms of insulation for ordinary industrial equipment, such as external wrapping of pipelines and small reaction vessels, it helps to maintain equipment temperature and reduce energy consumption.
