UNIGARD™ RE DFDC-1638 Black is a non-halogen, highly flame retardant, thermoplastic, low smoke, low corrosive, and low toxic compound. It is designed for general purpose cable jacket applications. Used as jacket, it easily passes the IEEE-383/UL-1685 (Limited Smoke Test) vertical tray cable burn tests. Cable construction, of course, plays an important role in flame performance. It can be used as a jacket on cables operating at up to 90°C.

This compound can replace PVC, low smoke PVC, and halogenated rubbers as a jacket with excellent fire safety (low smoke, low corrosivity, and low toxicity) and good property balance. This compound meets or exceeds many industry jacket specifications: UL-1277 Tray Cable, UL Subject 444 for general purpose communication cable, mass transit applications, and several international applications.

As a non-halogen, flame retardant jacket, DFDC-1638 Black is also designed to replace the conventional non-halogen jacket products. This compound has much better process-ability than current non-halogen jacket products. It can sustain a higher extrusion temperature (up to 392°F [200°C]), and can be extruded in the typical single-flight metering PE screws.
