Does polyurethane rigid foam insulation composite board contain formaldehyde?

Polyurethane rigid foam insulation composite panels usually do not contain formaldehyde <\/strong>, and their environmental protection is mainly reflected in the following aspects:<\/p>

1. Material characteristics <\/strong>: Polyurethane rigid foam is generated through a chemical reaction between isocyanate and polyol. There is no need to add formaldehyde as a cross-linking agent or preservative during the production process. Its core material has a closed porosity rate of over 90%, forming a dense structure that effectively prevents gas penetration and further reduces the risk of harmful substance release.<\/p><\/li>

2. Environmental certification <\/strong>: Polyurethane rigid foam insulation composite panels produced by regular manufacturers must pass national environmental standards testing. For example, the amount of formaldehyde released must comply with the requirements of GB 18580-2017 'Formaldehyde Release Limits in Artificial Panels for Interior Decoration Materials and Their Products' (≤0.124mg/m³). Some high-end products even reach E0 level (≤0.050mg/m³) or ENF level (≤0.025mg/m³), which is far below the safety threshold.<\/p><\/li>

3. Application scenarios <\/strong>: This material is widely used in closed environments such as building exterior walls and cold storage. If it contains formaldehyde, it will harm human health. Therefore, the industry has extremely strict formaldehyde control, and production companies must pass ISO 14001 environmental management system certification to ensure the environmental protection of the entire process from raw materials to finished products.<\/p><\/li>

4. Test report <\/strong>: The report issued by a third-party testing agency shows that the formaldehyde release amount of polyurethane rigid foam insulation composite panels is usually 'not detected' or lower than the instrument detection limit (such as ≤0.005mg/m³), proving that it has no formaldehyde release risk.<\/p><\/li><\/ol>
