Overview of Halogen-Free Wire Ducts
Halogen-free wire ducts are engineered for enhanced safety, as they do not emit toxic or corrosive gases and resist flame propagation due to surface carbonization. They function effectively across a broad temperature range (-10° to -50°C and +90° to +120°C) and exhibit strong resistance to chemical and marine environments, along with high insulating capabilities. The open type design includes rounded corners to prevent abrasions and damage to cable insulation during installation.

Material Specifications
The ducts are constructed from Noryl XTRA Class 1 (UL94-V0) and PC-Polycarbonate Class 2 (UL94-V0), ensuring flame resistance and safety. These materials possess excellent mechanical, thermal, and electrical properties, with specific resistance to various chemicals and environmental conditions.

Installation and Practicality
The ducts are designed for easy assembly, with a module length of 0.5 meters, which reduces installation time and storage requirements. This design also minimizes waste, particularly given the high cost of raw materials.

Recommended Applications
These ducts are ideal for use in public buildings with high occupancy, underground transport systems, hostile environments such as nuclear reactors and petrochemical plants, and military applications. They can accommodate cables up to 3x10 of types NO7G9-K and FG100M1, in compliance with CEI standards.

Technical Properties
Mechanical properties include tensile strength, elongation, and impact resistance, with polycarbonate offering superior impact resistance. Thermal properties cover softening temperature and thermal conductivity, while electrical properties include volume resistivity and dielectric strength. The materials also demonstrate flame resistance, with an oxygen index of 35% and self-extinguishing capabilities.

Performance Standards
The ducts comply with various standards, including ASTM E 662 for optical density, CEI 20-37 for toxicity index, and VDE standards for corrosivity index, ensuring their safety and reliability in diverse applications.
