Because many chimneys operate at relatively high temperatures—typically between 50 and 180°C—and the flue gas composition is complex, standard resins often fail to meet these demanding conditions. Therefore, the key to selecting both the liner resin and the structural‑layer resin lies in their ability to withstand corrosion under high‑temperature exposure. The choice of structural‑layer resin must also satisfy high‑temperature resistance requirements, while ensuring that its elongation at break is compatible with that of the liner resin. To facilitate installation, we fabricate the chimney in sections according to the customer’s specifications and assemble it on site; alternatively, we can tailor the installation process to the customer’s preferences.
