| High Light | Corrosion Resistant Rock Wool Boards ，Customizable Rock Wool Boards ，Yellowish Brown Stone Wool Board | ||
Made from raw materials like basalt and diabase through high-temperature melting and fibrosis, rock wool boards boast core properties such as fire resistance, thermal insulation, sound absorption, corrosion resistance, and strong chemical stability. Beyond industrial insulation and building energy efficiency, they find vital applications in the transportation sector.
Rock wool boards stand out as an ideal material for the automotive sector due to three core advantages. First, they boast excellent fire resistance, withstanding temperatures over 800°C to act as a reliable barrier against heat spread—this is particularly critical for preventing safety hazards like battery thermal runaway. Second, they offer dual thermal and acoustic performance: not only do they reduce heat transfer to preserve energy efficiency, but they also absorb noise effectively, greatly enhancing in-cabin comfort for passengers. Third, they are lightweight yet stable, with a density ranging from 40 to 120kg/m³ that adds minimal weight to vehicles (avoiding extra energy consumption) while maintaining strong chemical stability, which allows them to resist corrosion from engine fluids or external moisture.
Good Performance
For new energy vehicles (NEVs), where battery safety and performance are top priorities, rock wool boards play a key role by being integrated into battery pack insulation and fire-resistant layers. They insulate the battery from extreme temperatures: in cold weather, they slow down the battery’s capacity decay to extend the vehicle’s driving range, and in the event of thermal runaway, they block the spread of high temperatures to other parts of the vehicle, significantly reducing fire risks that could threaten both the vehicle and its occupants.
Extra Usages
In traditional fuel vehicles, rock wool boards target the common issues of heat and noise. Within the engine compartment, they are installed as sound absorption layers to muffle mechanical noise from the engine, lowering in-cabin noise levels and creating a quieter driving environment. On the undercarriage, they serve as thermal insulation layers to isolate high temperatures from the exhaust pipe—this not only prevents damage to undercarriage components like wiring or plastic parts but also reduces heat transfer into the cabin, improving the efficiency of the air conditioning system during summer. Additionally, in some vehicle models, thin rock wool panels are used in door panels or floor mats (combined with other materials) to further enhance sound insulation, reducing road noise and wind noise during driving and elevating the overall ride comfort.
