Our low-chloride heat resistant wool board is specially engineered for stainless steel equipment, sensitive metal pipelines, nuclear power, and electronics industries where chloride-induced corrosion is a concern. Using specialized formulation and manufacturing processes, the chloride ion content ≤10ppm—far below standard rock wool products—effectively preventing chloride stress corrosion cracking. Maintaining up to 650°C continuous service temperature and Class A non-combustible fire performance, it is the preferred insulation material for stainless steel tanks, austenitic steel pipelines, nuclear facilities, and cleanroom ducts.

• Insulation for stainless steel tanks, reactors, austenitic stainless steel pipelines
• Flanges, valves, nuclear facilities
• Electronics industry cleanroom ducts, semiconductor equipment
• Other industrial equipment sensitive to chloride corrosion

• Chloride Content ≤10ppm - Extremely Low Corrosion Risk: Special formulation achieves chloride content ≤10ppm, far below conventional products, effectively preventing chloride stress corrosion cracking.
