The PU foam insulation for industrial applications is tailored to the specific conditions of the industry in terms of thermal and environmental considerations. Rigid PU foam insulation has high-performance thermal resistance and effectively mitigates heat transfer in industrial facilities, pipelines, and storage vessels such as tanks. Its closed-cell structure also effectively resists moisture, which helps to limit condensation and mold proliferation. This type of industrial insulation foam is rugged and resistant to the harsh conditions of industry, including chemical exposure and mechanical loads. PU rigid foam for industrial purposes has multiple application techniques, including spray, board, and in-situ molding, which provide optimal flexibility and effectiveness with respect to the diversity of industrial needs, thereby improving the energy efficiency and operational performance of the complete system.
