Product Description
DFDA-1675 NT is a non-halogen, flame retardant, polyolefin based thermoplastic compound for applications in communication cables and jacketing. DFDA-1675 NT offers superior electrical properties, flame retardance, processability, and flexibility. Once commercialized, DFDA-1675 NT will be known as UNIGARD™ RE DFDA-1675 NT.

Features
DFDA-1675 NT has the following features:
  • Highly flame retardant
  • Excellent electrical properties and moisture resistance
  • Environmentally friendly (lead-free, halogen-free, and sulfur/antimony-free)
  • Low smoke, low corrosivity, and low toxicity
  • Good balance of toughness and flexibility
  • Ease of extrusion and no special screw required
  • ROHS compliance

Usage Recommendations and Specifications
DFDA-1675 NT is a cross-web compound for Plenum Category 6 communication cables requiring UL NFPA 262 flame test rating. This flame test rating is cable construction dependent and individual testing and listing are required. Each manufacturer utilizing DFDA-1675 NT must contact the standards agency o determine what evaluations, if any, are required to receive application approvals.

Additional Information
Colorability
  • DFDA-1675 NT EXP1 is a colorable compound. The color masterbatch materials recommended for use with polyethylene or ethylene copolymer wire and cable products are suitable for use in DFDA-1675 NT EXP1. Where optimal electrical performance is required, use a polyethylene homopolymer based color masterbatch to avoid deterioration of dielectric properties. Generally speaking, color masterbatch added at the level from 0.5 to 1.0% by weight gives adequate color and disperses well in the extrusion process. For black jacket applications, UV resistance can be also achieved by adding a carbon black masterbatch. However, the level may be higher, and depends on the type of carbon black masterbatch and the test requirement for the application.
