Understanding Flame Resistance (LSZH/Fire Retardant)
Material Composition: These end caps are manufactured from Low Smoke Zero Halogen (LSZH) or fire-retardant polymers (e.g., polycarbonate with UL94 V-0 rating). This ensures minimal smoke, toxic fumes, and halogen emissions during fire events, enhancing safety in enclosed spaces.
Safety Standards:
✅ They comply with stringent international standards:
✅ UL94 V-0: Prevents flame propagation.
✅ EN 13501-1: Achieves fire performance ratings like C-s2, d0.
✅ ETL Verification: Meets UL1685-4 and IEC 60754-1 for low smoke and zero halogen emissions.
✅ Size Range: Available for microduct outer diameters (OD) from 5mm to 27mm.
✅ Temperature Tolerance: Operates in -40°C to +60°C environments.
✅ Mechanical Strength: Pull-out forces range from 400N.
✅ Pressure Ratings: Approved for use at 16–25 bar working pressures.
Tool-Free Installation: Push-fit design allows quick, secure connections without special tools.
Environmental Protection:
✅ IP68 Rating: Fully waterproof and dustproof.
✅ Pressure Resistance: Withstands up to 16–25 bar pressure, ideal for air-blown fiber systems.
✅ Durability: Designed for long-term use (25+ years) with corrosion-resistant materials.
✅ Color Coding: End caps are often color-coded by size for easy identification during installation.
✅ In-Building Installations: Essential for confined spaces like tunnels, mass transit corridors, and high-rise buildings where fire safety is critical.
✅ Confined Spaces: Protects against toxic gas emissions in poorly ventilated areas (e.g., control rooms, behind-the-wall setups).
✅ FTTx Networks: Seals microducts of various diameters (ranging from 5mm to 27mm) in fiber-to-the-home (FTTH) infrastructure.
