We specialize in manufacturing High Temperature Resistance Mineral Wool for extreme heat environments, using premium basalt fibers with enhanced thermal stability. Processed at high temperatures and reinforced with special additives, this mineral wool withstands continuous operating temperatures up to 800℃, making it ideal for industrial high-heat applications. As a manufacturer focused on high-temperature materials, we ensure dimensional stability and insulation performance even under thermal stress. It is non-combustible, non-toxic, and resistant to thermal shock, providing reliable protection for equipment and personnel.

FAQ
Q: Can the High Temperature Resistance Mineral Wool be used in contact with open flames?
A: It can withstand short-term open flame exposure (≤10 minutes) at 1000℃, but continuous direct flame contact is not recommended. For such applications, we suggest adding a refractory coating.
Q: What is the service life at 800℃ continuous operation?
A: It maintains stable performance for 8-10 years at 800℃. For higher temperatures (800-900℃), the service life is 5-7 years with regular inspections.
Q: How to install this mineral wool on high-temperature pipelines?
A: Use high-temperature resistant stainless steel straps (temperature rating ≥1000℃) for fixation, spaced 300-400mm apart. Avoid using plastic or low-temperature fasteners that may melt.
