Описание материалов:

Halogen-free flame retardant material, used for communication cables and sheathing materials

DFDA-1675 NT is a halogen-free flame retardant polyolefin thermoplastic material, used as a material for communication cables and sheathing. DFDA-1675 NT has excellent electrical properties, flame retardant grade, processability and flexibility. After the official launch, DFDA-1675 NT will be called UNIGARD™RE DFDA-1675 NT.

Features
DFDA-1675 NT has the following characteristics:

high flame retardant performance

Excellent electrical properties and moisture resistance

Environmental protection (lead-free, halogen-free, sulfur-free/antimony-free)

low smoke, low corrosion and low toxicity

Has a good balance between toughness and flexibility

The extrusion process is easy, no special screw is required

compliance with ROHS regulations

Recommendations and specifications for use
DFDA-1675 NT is a transverse substrate material for Plenum Category 6 communication cables that require UL NFPA 262 combustion test grades. This combustion grade depends on the cable structure and requires separate testing and certification. Each manufacturer using DFDA-1675 NT must consult a standard testing organization to determine which tests and evaluations (if any) are required to obtain application certification.

Дополнительная информация
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.
