High flame retardant cable composites are crucial in areas with strict fire safety requirements. Their core applications include data centers, smart buildings, rail transit, energy and power, and industrial automation. Different scenarios have differentiated requirements for cable flame retardancy, low smoke zero halogen (LSZH), high temperature resistance and other properties.
Core requirements:
High flame retardancy (IEC 60332-3A / UL 94 V-0): prevent fire from spreading in dense cables.
Low smoke zero halogen (LSZH): reduce toxic smoke, ensure personnel escape and equipment safety.
High temperature resistance (90°C~125°C): adapt to high-load heat dissipation environment of servers.
Typical materials:
Halogen-free flame retardant polyolefins (FR-PE/FR-PP), such as Dow Chemical's ECCOH™.
Ceramic silicone rubber (forms a fire barrier at extreme high temperatures).
Industry standards:
TIA-942 (data center cabling standard) requires cables to pass IEC 60332-3A and UL 910 (Plenum level).
Core requirements:
Low smoke and non-toxic (EN 45545-2): EU standards strictly control the release of combustion toxic gases (such as CO, HCL).
Oil resistant and vibration resistant: adapt to the locomotive operating environment.
Bundled flame retardant (IEC 60332-3C and above): prevent the spread of fire in the tunnel.
Typical materials:
Halogen-free cross-linked polyethylene (XLPE): has both flame retardancy and mechanical strength.
Flame retardant PVC (containing phosphorus flame retardant): low cost, but must comply with RoHS.
Industry standards:
EN 45545-2 (EU railway fire protection), GB/T 19666 (China flame retardant cable standard).
Core Requirements:
CMR (UL 1666): Vertical shaft cables must prevent fire from spreading across floors.
Low Smoke (IEC 61034): Reduce the risk of people inhaling toxic smoke.
Flexible Design: Facilitates complex wiring.
Typical Materials:
Flame-retardant PVC (containing Sb₂O₃ synergist): Widely used in ordinary building cables.
LSZH Thermoplastic Elastomer (TPE): Replaces PVC for high-end projects.
Industry Cases:
NFPA 70 (NEC) in the United States requires CMR/MPR-grade cables for high-rise buildings.
Core Requirements:
High Temperature Resistance (150°C+): For example, photovoltaic cables must withstand UV and high temperatures.
Oil/Chemical Resistance: Petrochemical Plants, Offshore Wind Power Scenarios.
High Flame Retardant (IEC 60332-3B): Prevent fires in substations.
Typical materials:
Cross-linked halogen-free polyolefin (XLPO): used for photovoltaic cables (such as TUV certification).
Fluoroplastic (such as PTFE): high-cost solution in extreme environments.
Industry standards:
IEC 62930 (photovoltaic cables), IEEE 383 (nuclear power plant cables).
Core needs:
Anti-mechanical damage: friction and extrusion protection in factory environments.
Flame retardant + oil resistant (UL 1277): such as robot cables.
EMI shielding: prevent signal interference (coaxial cable applications).
Typical materials:
Flame retardant polyurethane (PUR): excellent wear resistance, suitable for drag chain cables.
Shielding materials containing aluminum and magnesium layers: improve anti-interference capabilities.
