        \n
      • PU insulation is resistant to mechanical stress, moisture, and chemical degradation, ensuring long-term performance in harsh industrial environments.<\/li>\n
      • Its closed-cell structure provides excellent resistance to water ingress, preventing issues such as corrosion under insulation (CUI).<\/li>\n<\/ul>\n<\/li>\n
      • \n

        Versatility<\/strong><\/p>\n

          \n
        • Polyurethane can be applied in various forms, including rigid foam boards, spray-applied coatings, or pre-insulated pipe systems, allowing for flexibility in design and installation.<\/li>\n
        • It can be used for both above-ground and underground pipelines.<\/li>\n<\/ul>\n<\/li>\n
        • \n

          Lightweight<\/strong><\/p>\n

            \n
