Stone Wool Insulation with a Built In Corrosion Inhibitor

ROCKWOOL is meeting the challenge of CUI. Introducing ProRox with CR-Tech (Corrosion Resistant Technology), the industry’s first stone wool insulation with an embedded corrosion inhibitor for industrial piping systems. Upon contact with water, the CR-Tech inhibitor is “activated” to form a protective, corrosion-mitigating film on the outer pipe surface. This innovative solution, combined with WR-Tech (Water Repellency Technology), ensures that plant owners get unmatched water repellency AND corrosion resistivity in one product (adding longevity to their important assets). ProRox with CR-Tech outperforms alternative hydrophobic insulation materials, delivering at least 5X better corrosion mitigation. Additionally, CR-Tech recently received the MP Corrosion Innovation of the Year Award, at the 2025 AMPP conference. Selected by a panel of corrosion experts, winning technologies have to demonstrate “significant positive impact in controlling corrosion”.
