Yes, fiberglass is known for its excellent heat resistance. It is designed to maintain its structural integrity and mechanical properties even at elevated temperatures. The heat resistance of fiberglass is one of its key advantages, making it a preferred material in industries that require thermal insulation and fire protection.
When fiberglass is heated beyond its melting point, it begins to lose its structural integrity. Initially, fiberglass may soften and become more pliable; however, as the temperature continues to rise, it will eventually melt and lose its shape. If exposed to extreme heat, the resin used in fiberglass can also begin to decompose, which may lead to the release of hazardous fumes.
