Covestro Makrofol® BL 6-2 820803 Polycarbonate
Categories:	Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Molded
Material Notes:	Characterization: Makrofol BL 6-2 820803 is a virtually glare free, scratch resistant, black translucent extrusion film based on Makrolon® polycarbonate. Properties / Applications: Makrofol BL 6-2 820803 typical applications are automotive instrument panels, illuminated gauges, dials and graphics, front panels and scales on radios and control consoles, and diffusors on projection screens. Makrofol BL 6-2 820803 is available in a standard thickness of 0.016 ” (400 microns). Other thicknesses are available on request. The surface combination of Makrofol BL 6-2 820803 is one side fine velvet and one side very fine matte. As with any product, use of Makrofol BL 6-2 820803 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. As of 1 September 2015, Bayer MaterialScience was separated from Bayer AG and officially adopted its new name – Covestro.
