High Temperature Resistance Of Rock Wool Rolls
Dec 09, 2025| High-Temperature Resistance Core Parameters: Rock wool rolls are made primarily of basalt, melted at high temperatures, with a melting point exceeding 1000℃.<sup>1</sup> In actual use, the high-temperature resistance indicators vary slightly between different products:
Long-term operating temperature: Generally 600℃<sup>4</sup>, suitable for continuous high-temperature environments such as industrial equipment and pipelines.
Thermal stability: Will not shrink, become brittle, or melt under short-term exposure to 300℃<sup>6</sup>, only begins to soften above 500℃.
High Temperature Resistance Guaranteed
Features and Description
Raw Material Characteristics: Basalt has a melting temperature exceeding 1400℃, ensuring the resulting fibers possess a natural high-temperature resistance foundation.
Fiber Structure: Slender fibers form a porous structure with low thermal conductivity, effectively blocking high-temperature transfer.
Chemical Stability: Contains no organic additives, releases no toxic gases at high temperatures, has a neutral pH, and is non-corrosive to metals. High Temperature Resistance Applications
Industrial Applications: Thermal insulation for boilers, flues, heat exchangers, etc. Building Applications: Inner linings for high-temperature workshops and control rooms; aluminum foil-faced versions especially enhance resistance to heat radiation.
Special Environments: Ships, large storage tanks, and other environments with stringent fire resistance and high-temperature resistance requirements.
