Coaxial Cable Environmental Protection Materials Promoted

As the backbone of modern communication infrastructure, coaxial cables are undergoing a significant transformation driven by global environmental regulations and technological innovations. The promotion of eco-friendly materials in coaxial cable manufacturing has become imperative, not only to meet stringent regulatory requirements but also to enhance performance and sustainability across industries.

Regulatory Pressures Drive Material Innovation

The landscape of environmental regulations for electronic materials has tightened considerably. China’s mandatory national standard GB 26572-2025, issued in August 2025 and set to take effect in 2027, expands restricted hazardous substances from 6 to 10 categories, including four additional phthalates, while introducing stricter labeling requirements with digital identifiers like QR codes . Concurrently, the EU’s REACH regulation has added 16 CMR (carcinogenic, mutagenic, reprotoxic) substances to its restriction list since September 2025, setting strict limits for substances in mixtures (0.1% for carcinogens and mutagens, 0.3% for reproductive toxins) . These regulations have accelerated the phase-out of traditional materials like PVC and halogenated flame retardants in coaxial cables.

Traditional coaxial cables face three critical environmental challenges: toxic emissions from halogen-containing materials during combustion, low recyclability of mixed polymer-metal structures, and high carbon footprints from petroleum-based insulators. For instance, conventional PVC-sheathed cables release toxic halogen gases when burned, with smoke density exceeding safety thresholds, while their metal components often end up in landfills despite high recovery potential.

Technological Breakthroughs in Eco-Friendly Materials

The industry has responded with innovative materials that balance environmental performance and technical specifications:

1. Halogen-Free Flame Retardant Sheaths: Low Smoke Zero Halogen (LSZH) polyolefins have emerged as a superior alternative to FRPVC. These materials emit less than 0.5% halogen gas during combustion and achieve smoke density transmittance above 60%, significantly improving fire safety in indoor and 轨道交通 environments . Products like the CA195FR coaxial cable demonstrate compliance with 的 UL/CSA CMR and FT4 ratings, making them suitable for both in-building and outdoor applications .
2. Bio-Based Insulators: Modified polylactic acid (PLA) composites, enhanced with isosorbide diesters and adipate plasticizers, have overcome traditional brittleness issues. These bio-based materials achieve 200-350% elongation at break while maintaining 120°C heat resistance through radiation cross-linking, offering a low-carbon alternative to petroleum-based polyethylene .
3. Recyclable Shielded Structures: Advanced designs combining aluminum-plastic composite tape (providing ≥70dB shielding at 30MHz-1GHz) and tinned copper braids (85%+ density) enable efficient metal recovery. Mechanical processing followed by spouted bed elutriation achieves approximately 90% recovery efficiency for steel-coated copper in coaxial cables .

Performance Advantages in Key Applications

Eco-friendly coaxial cables deliver superior performance across critical sectors:

• 5G Infrastructure: Foamed polyethylene insulators with dielectric constants around 1.5 reduce signal loss, while dual-shield designs lower bit error rates by 43% in dense urban macro 站 deployments, achieving 99.98% link availability .
• Green Buildings: LSZH-sheathed cables meet stringent fire safety standards, supporting sustainable construction certifications.
• Rail Transit: Halogen-free materials minimize toxic emissions in enclosed spaces, enhancing passenger safety during incidents.

These materials also contribute to lifecycle energy savings. According to China’s Academy of Information。Information and Communications Technology, solid insulation cables reduce signal amplification requirements, lowering overall system energy consumption despite slightly higher insertion loss compared to foam alternatives .

Future Trends and FRS Commitment

The promotion of environmental protection materials in coaxial cables will continue to be driven by three factors: evolving regulations requiring full material traceability, advancing material science enabling higher-performance bio-based composites, and circular economy models optimizing recycling processes.
