Halogen Free Fire Retardant Nylon PA66 Compounds For Safe Optical Cable Connector Housings

Flame Retardant Nylon PA66 Compounds For Safe Optical Cable Connector Housings

Product Description

Flame Retardant Nylon PA66 compounds are specially designed for the production of optical cable connector housingsused in telecommunication, power transmission, and data infrastructure projects. By integrating halogen-free or halogen-based flame-retardant additives, these materials achieve UL94 V-0 or V-2 fire safety ratings, significantly reducing the risk of fire propagation in electrical installations.

In addition to flame resistance, this PA66 grade provides high tensile strength, impact resistance, dimensional stability, and excellent electrical insulation, ensuring reliable performance in demanding environments. Optical cable connector housings produced with this material offer secure cable clamping, environmental sealing, and long-term durability, making them ideal for both indoor and outdoor network installations.

Properties Data Sheet

Notes: The general guidelines are only for reference. Exact settings have to follow the product and machine conditions.

Avoid contact with other materials, dust and debris in the injection processing.

Avoid long time stay in the barrel in the injection processing.

Precautions

• Ensure pre-drying at 80–90°C for 4–6 hours to prevent moisture-related molding defects and surface blistering.

• Avoid exposure to excessive molding temperatures above 300°C to maintain flame-retardant effectiveness.

• Store compounds in moisture-proof packaging, especially before injection molding, to preserve processing stability.

• Confirm compliance with RoHS & REACH regulations for use in telecommunication and electrical systems.

• For outdoor applications, pairing with UV stabilized or heat stabilized grades is recommended to enhance durability.

Features, Advantages & Properties

• Superior Flame Retardancy: Achieves UL94 V-0 / V-2 rating, reducing fire risks in telecommunication networks.

• Electrical Insulation: Maintains excellent dielectric properties, preventing short circuits in optical/electrical systems.

• High Mechanical Strength: Withstands cable insertion forces and environmental stresses without cracking.

• Dimensional Stability: Low shrinkage and warpage ensure precise housing fitment.

• Weather Durability: Optionally available with UV stabilizers for long-term outdoor use.

• Eco-Friendly Options: Halogen-free versions meet stricter international environmental standards.

Working Principle & Applications

The addition of flame-retardant additives in PA66 modifies the polymer’s thermal decomposition pathway, enabling self-extinguishing properties when exposed to open flame. The material also provides consistent mechanical strength and insulation, making it a safe and reliable choice for optical communication equipment.

Applications include:

• Fiber optic cable connectors for broadband and telecommunication systems

• Power distribution housings requiring fire-safe cable entry points

• Data center cable management systems with high flame resistance standards

• Outdoor telecom junction boxes exposed to electrical and weather stress
