Our high temperature resistant silicone foam tube is a high-performance flexible tubular material specially developed for long-term high-temperature operating environments, including new energy vehicle thermal management, energy storage equipment, industrial high-temperature pipelines, electrical wiring harnesses and heating mechanical equipment. It is manufactured from high-purity platinum-vulcanized heat-resistant silicone raw materials via one-step continuous closed-cell extrusion foaming technology. Fully compliant with RoHS, REACH, UL94 V-0 and industrial high-temperature safety standards, this tubing features stable high-temperature resistance, low thermal conductivity thermal insulation, waterproof sealing, shock absorption and electrical insulation integrated functions. It effectively isolates high-temperature heat radiation, reduces pipeline heat loss, avoids equipment overheating failure, and provides long-term reliable protection for all kinds of high-temperature medium pipelines and wiring harnesses.
Core Performance & Structural Advantages
Equipped with dense and uniform closed-cell micropore structure, smooth inner and outer tube walls, consistent wall thickness and ultra-high soft resilience, this foam tube fits tightly on various pipelines and wiring harnesses. It is easy to cut, sleeve and bend without shedding foam scraps or scratching matched metal and plastic components. It solves the core defects of ordinary foam tubes such as high-temperature softening, shrinkage, aging cracking and rapid performance attenuation, with outstanding high-temperature stable comprehensive performance:
- Ultra-Wide Stable High & Low Temperature Resistance
Long-term continuous working temperature range: -60℃ ~ 250℃, instantaneous peak heat resistance up to 280℃. It remains soft and flexible without embrittlement or cracking under low-temperature freezing environments; no softening, collapse, shrinkage or release of toxic volatile substances under long-term high-temperature baking. Thermal insulation and mechanical performance stay unchanged after thousands of cold-hot cycle alternations, far exceeding conventional silicone foam tubes.
- Low Thermal Conductivity Efficient Thermal Insulation & Anti-Scald
The closed-cell air interlayer forms stable heat insulation barrier, thermal conductivity ≤0.035W/(m·K). It locks internal pipeline heat efficiently, blocks outward heat dissipation, greatly reduces heat loss of steam, hot water and heating circulation pipelines, cuts equipment energy consumption by over 30%, and lowers pipeline surface temperature to prevent staff scald accidents.
- UL94 V-0 Halogen-Free Flame Retardant Safety
Optional halogen-free low-smoke flame retardant formula meets strict UL94 V-0 fire grade. It self-extinguishes rapidly after leaving fire source, no molten drips and low toxic smoke during combustion, forms a stable fire barrier to block flame spread along pipelines and wiring harnesses, reducing thermal runaway and circuit ignition risks of high-temperature equipment.
- 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 mold breeding, prevents circuit short circuit and component corrosion caused by moisture invasion, and keeps internal pipelines dry and clean for long-term unattended 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.
- Superior Electrical Insulation & Long-Term Weather Resistance
Volume resistivity ≥10¹⁴Ω·cm, reliable insulation performance to isolate current leakage and electromagnetic interference, fully protecting high-temperature wiring harnesses, connectors and electrical components. Added with anti-UV and anti-ozone anti-aging additives, it resists long-term outdoor sunlight, wind and rain erosion, no hardening, yellowing or cracking after 8–10 years of continuous service life.
- 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 production line assembly efficiency.
- Eco-Friendly & Chemically Inert Compatibility
Halogen-free, non-toxic, odorless and heavy metal-free, fully compliant with global environmental protection regulations. No chemical reaction or corrosion with metal pipelines, plastic wires and mechanical accessories, no harmful precipitation pollution to matched components.

Precision Manufacturing & Strict Quality Control
Targeting long-term high-temperature stable operation requirements of pipeline systems, we implement full-process industrial-grade quality management and multi-dimensional batch testing:
- High-temperature resistant dedicated raw material screening: Platinum-cured silicone compound matched with heat-resistant anti-aging additives; all raw materials pass high-temperature endurance, cold-hot cycle and environmental migration tests before production;
- One-step closed-cell extrusion foaming process: Ensures uniform micropore distribution, consistent tube wall thickness and no attenuation of long-term high-temperature performance;
- Full-item performance batch inspection: Each batch undergoes high-temperature aging test, thermal conductivity test, flame retardant 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 long-term working temperature to ensure close fitting and optimal heat insulation effect;
- Do not violently stretch, twist or pull the tube body during installation, to avoid damaging internal closed-cell structure and attenuating high-temperature resistance and thermal insulation performance;
- Avoid long-term direct contact with strong acid, strong alkali and high-concentration corrosive solvents to prevent material aging and performance 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 long-term temperature range, otherwise heat preservation and protection functions will fail;
- Regularly inspect the tube body during equipment operation; replace timely if aging, cracking or hardening occurs.
