Covestro Makrolon® SK1 sheet Polycarbonate
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	Skylight prismatic Makrolon® SK1 sheet‘s prismatic pattern is optimized to diffuse and distribute light while maintaining high light transmission, making it the material of choice for daylighting applications. The product is available with a UV enhanced cap layer in both clear and white. Makrolon SK1 can be drape or thermoformed for use in contoured applications such as domed skylights. In either flat or contoured geometries, it has a higher impact resistance compared to acrylic or glass. Makrolon SK1 has a Limited Product Warranty against breakage, yellowing, and loss of light transmission. Applications: Awnings, entryway canopies, skylights, barrel vaults, glazed archways, covered pedestrian walkways, and sloped, vertical, and curved glazing Information provided by Covestro
