<p>A striped and celled Venetian blind slat is made of a poly carbonate material mixed with the additives such as water, PE-wax, barium sulfate (BaSO4), Calcium carbonate (CaCO3), talc, antimony (III) Oxide (Sb203), and acrylic compounds. The mixture is extruded by an extruder at a temperature ranging between 200 and 300 degrees in Celsius. The extruded mixture is foamed and is then formed in a vacuum mold into the slat of uneven thickness and having irregular stripes (24) and cells (25). <IMAGE></p> |
