Our flame-retardant silicone foam tube is a high-performance fire-proof tubular material specially developed for new energy vehicles, energy storage cabinets, industrial high-temperature pipelines, electrical wiring harnesses and high-fire-risk equipment. It is manufactured from high-purity platinum-vulcanized silicone compound with halogen-free low-smoke flame retardant additives, adopting continuous precision closed-cell extrusion foaming technology. Fully compliant with UL94 V-0, RoHS, REACH, IEC 60332-1 and industrial safety standards, this tubing integrates top-grade flame retardancy, thermal insulation, waterproof sealing, shock absorption and electrical insulation functions. It blocks flame spread along pipelines and wiring harnesses, isolates high-temperature heat transfer, and provides long-term reliable fire safety protection for all heat-prone pipeline systems.
Core Performance & Structural Advantages
Equipped with dense, uniform closed-cell micropore structure, smooth inner and outer tube walls, consistent wall thickness and ultra-high soft resilience, this flame-retardant foam tube fits tightly with various pipelines and wire harnesses. It is easy to cut, sleeve and bend without shedding foam scraps or scratching matched components. It solves the core safety defects of ordinary foam tubes such as easy combustion, dripping molten material and heavy toxic smoke, with targeted fire-resistant comprehensive performance:
- UL94 V-0 Top-Grade Halogen-Free Flame Retardancy
Adopts eco-friendly halogen-free flame retardant formula, meets strict UL94 V-0 fire standard. It self-extinguishes rapidly within 10 seconds after leaving fire source, no molten drips, low smoke density and zero toxic gas emission during combustion. It forms a stable fire barrier to effectively block flame spread along pipelines and wiring harnesses, greatly reducing thermal runaway and circuit ignition risks in battery and high-temperature equipment.
- Ultra-Wide Temperature Stability & Thermal Insulation
Continuous working temperature range: -60℃ ~ 230℃, instantaneous short-term heat resistance up to 260℃. It remains soft and flexible without embrittlement under low-temperature freezing, and will not soften, collapse or decompose under long-term high-temperature baking. The closed-cell structure owns ultra-low thermal conductivity, effectively locking internal heat and isolating external heat radiation to achieve energy-saving thermal preservation and anti-scald effects.
- Fully Closed-Cell Waterproof, Dustproof & Anti-Condensation
Compact closed-cell structure with ultra-low water absorption rate ≤0.5%, completely isolating rainwater, humid air, oil stains and corrosive gas penetration. It avoids pipeline surface condensation, metal rust and mildew breeding, prevents circuit short circuit and component corrosion caused by moisture invasion, and keeps internal pipelines dry and clean for long-term operation.
- High Resilience Shock Absorption & Noise Reduction
Compression set ≤7%, fast rebound after long-term extrusion without permanent deformation. It absorbs vibration and friction noise generated by pipeline operation and equipment running, buffers collision and extrusion between pipelines and equipment, reduces pipeline wear and eliminates resonance noise in vehicle and industrial equipment.
- Stable High-Voltage Electrical Insulation
Volume resistivity ≥10¹⁴Ω·cm, reliable insulation performance to isolate current leakage and electromagnetic interference. It effectively protects high-voltage wiring harnesses, connectors and electrical components, avoiding short-circuit safety hazards in power distribution and energy storage equipment.
- Excellent Weather Resistance & Long Service Life
Added with anti-UV and anti-ozone anti-aging additives, it resists long-term outdoor sunlight, wind and rain erosion and temperature cycle alternation. No hardening, yellowing or cracking after 8–10 years of continuous use, matching the service life of new energy and industrial equipment.
- Precision Customization & Easy On-Site Installation
Customizable inner diameter, outer diameter, wall thickness, length and color as required; dimensional tolerance controlled within ±0.05mm for perfect sleeving fit. The ultra-flexible tube body supports arbitrary cutting and bending, adapts to complex multi-bend pipeline layout and improves assembly efficiency of production lines.
- Eco-Friendly & Inert Material Compatibility
Halogen-free, non-toxic, odorless and heavy metal-free, fully compliant with global environmental protection regulations. Chemically inert with metal pipelines, plastic wires and mechanical accessories, no chemical corrosion or adverse precipitation pollution to matched components.
Typical Application Scenarios
- New Energy Vehicles: Flame retardant insulation protection for power battery box pipelines, thermal management circulation tubes and engine compartment wiring harness sleeves
- Energy Storage Systems: Fireproof insulation sleeves for energy storage cabinet high-voltage wiring harnesses, battery module connecting pipelines and power distribution pipelines
- Industrial High-Temperature Equipment: Flame retardant thermal insulation for steam pipelines, heating circulation pipes and high-temperature mechanical equipment wiring

Precision Manufacturing & Strict Quality Control
Targeting high fire safety and long-term stable operation requirements of pipeline systems, we implement full-process industrial-grade quality management and multi-dimensional batch testing:
- Flame-retardant dedicated raw material screening: Platinum-cured silicone matched with low-smoke halogen-free flame retardant additives; all raw materials pass flame retardancy, high-low temperature cycle and environmental migration tests before production;
- One-step closed-cell extrusion foaming process: Ensures uniform pore distribution, consistent tube wall thickness and stable long-term flame retardant performance without attenuation;
- Full-item performance batch inspection: Each batch undergoes UL94 flame retardant test, thermal conductivity test, waterproof test, compression resilience test and UV aging test, factory qualification rate up to 99.8%.
Precautions
- Select matching inner diameter and wall thickness specifications according to pipeline outer diameter and working temperature to ensure close fitting and optimal flame retardant & insulation effect;
- Do not violently stretch, twist or pull the tube body during installation, to avoid damaging internal closed-cell structure and attenuating flame retardant performance;
- Avoid long-term direct contact with strong acid, strong alkali and high-concentration corrosive solvents to prevent material aging and fire resistance decline;
- Store in dry, cool and ventilated warehouse, keep away from open flames and high-temperature heat sources, avoid long-term heavy pressure stacking;
- Forbid continuous use beyond the rated temperature range, otherwise flame retardant and thermal insulation functions will fail;
- Regularly inspect the tube body during equipment operation; replace timely if aging, cracking or hardening occurs.
