What is the maximum temperature for fiberglass cloth?

Regarding the maximum operating temperature of fiberglass cloth, it mainly depends on its specific type, manufacturing process and whether it has been specially treated. The following is a summary based on information provided by different sources:

High-strength fiberglass cloth:
Maximum operating temperature: up to 550°C.

Features: It has good electrical insulation, thermal insulation and mechanical properties, and its strength is much higher than other fiberglass cloths of the same thickness.

Application range: It is suitable for equipment that requires high strength, such as fan blades.

Teflon (PTFE) fiberglass cloth:
Refractory temperature: The standard grade is -70~260°C, but it should be noted that the refractory temperature of Teflon fiberglass bulked yarn can reach 1580~1770°C, but this may refer to the performance of the yarn rather than the whole cloth.

Features: It has antibacterial, high temperature resistance, smooth surface, non-sticky and other characteristics.

Application range: It can be used in general industrial fields as a separator and gasket for plastic modules, and separation modules for certain products, etc.

High Silica Fabric Cloth:
Maximum temperature: It is mentioned that it can reach 1700°C, but the specific product description is relatively brief, which may refer to the excellent performance of this type of glass fiber cloth in high temperature environment.
Features: Remarkable high temperature resistance.

Silicone impregnated glass fiber thermal cloth:
Maximum working temperature: Although the maximum operating temperature is not directly given, it is mentioned that it can work continuously at -70°C to 280°C.
Features: It has good electrical insulation, ozone resistance, oxygen resistance, sunlight resistance and aging resistance.
Application range: Used in electrical insulation, non-metallic compensators, corrosion protection and other fields.

The maximum operating temperature of glass fiber cloth varies significantly due to its type and manufacturing process. For ordinary high-strength glass fiber cloth, its maximum operating temperature can reach 550°C; while for specially treated glass fiber cloth, such as Teflon glass fiber bulked yarn, its fire resistance temperature can reach extremely high levels (although this refers more to yarn performance). Therefore, when choosing glass fiber cloth, it is necessary to determine the appropriate type and specification according to the specific use environment and requirements.
