To assess R&D capabilities, focus on laboratory equipment, experienced engineers, and R&D centers, and review test reports and patent certificates. Reputable manufacturers invest in advanced equipment and aging testers to ensure product weather resistance; small workshops, however, have rudimentary equipment, and their products are prone to deformation and fading. The core of resin roofing tiles lies in the ASA resin co-extruded layer and the PVC substrate; formulations vary significantly, and high-quality raw materials combined with formulation technology...
When selecting a manufacturer of resin roofing tiles, focus on their in-house R&D capabilities and formulation optimization, and avoid prioritizing price alone. High-quality manufacturers pay close attention to raw material ratios; for example, they use ASA resin to ensure weather resistance, whereas substandard manufacturers may use recycled materials or ordinary PVC, which can lead to premature aging. In addition, advanced production equipment, such as extrusion lines, ensures that the panels are uniform and flat. Reviewing laboratory reports and aging test data is more...
