| Borstar FR4804 is a natural, thermoplastic polyolefin compound designed for flame retardant low voltage wire insulation and jacketing. As such, FR4804 offers a unique combination of good extrusion properties with a non-halogen flame retardant. FR4804 is specifically formulated for use in areas sensitive to smoke, corrosive fumes and toxic combustion products. Its flame retardant properties are conferred by a patented combination of inorganic filler and a novel, char-forming additive. FR4804 is readily pigmented to a variety of colors using standard wire & cable color concentrates designed for thermoplastic or crosslinked polyethylene. UV weather resistance is obtainable by the addition of a suitable carbon black or UV additive. BorstarFR4804 is intended to be used as a 90°C rated jacket for data cables. In addition it may also be used as a superior insulation or jacketing compound in PVC replacement applications. For most cable constructions FR4804 has sufficient flame retardant properties to satisfy single wire horizontal and European vertical burning flame tests. It is stabilized for use in contact with copper. Information provided by the Manufacturer. |
