Material Notes:
Borstar FR4802 is a natural, thermoplastic polyolefin compound designed for flame retardant low voltage wire insulation and jacketing. As such, FR4802 offers a unique combination of good extrusion properties with a non-halogen flame retardant. FR4802 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. FR4802 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.Borstar FR4802 is intended to be used as a 90°C rated jacket for power cables, flexible cords and building wires. In addition it may also be used as a superior insulation or jacketing compound in PVC replacement applications. For most cable constructions FR4802 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.
