New no-lead vinyl insulation compounds
Two new vinyl insulation compounds that provide a high-level of electrical performance needed in wet-location industrial and appliance wiring have been recently intoduced by Teknor Apex Vinyl Division, USA. These compounds contain none of the lead-based heat stabiliser formulations conventionally used in wire for such applications. The new compounds, Apex® 80853C and 80853F, have achieved Underwriters Laboratories listing for continuous service at 75 and 105°C in wet and dry locations, respectively, in wire designated in the National Electrical Code (NEC) as THWN. This is nylon-jacketed, vinyl-insulated building wire used in wet locations, typically for industrial equipment applications, such as control wires for motors. Other wet-location uses anticipated for the compounds include machine-tool wiring, appliance wire, and outdoor flexible cord.
Lead-based heat stabilizers have been widely used in conventional vinyl insulation and jacketing compounds because they provide PVC polymer with high-resistance to thermal degradation, which can compromise electrical performance. “The development of Apex 80853C and 80853F compounds is the latest achievement in a long-time programme at Teknor Apex to eliminate lead-containing additives from its compounds. A wide range of our wire and cable products are now free of lead stabiliser yet provide electrical properties as good as or better than the compounds that they have replaced”, commented Mr Donald G. Ouellette, industry manager
