In new energy power systems, new energy vehicles, high-temperature industrial equipment and electrical control cabinets, high-voltage wires, thermal management pipelines and heating pipelines face hidden fire risks caused by overheating, short circuits and high-temperature radiation. Flame retardant silicone foam tube is a professional tubular protective material developed for high fire safety demand scenarios, integrating UL 94 V-0 top flame retardant performance, efficient heat insulation and flexible buffer protection. Different from ordinary foam tubes, it adopts halogen-free low-smoke flame retardant silicone formula, which can effectively block flame spread and eliminate pipeline ignition hazards. Tengye produces high-performance flame retardant silicone foam tubes through integrated closed-cell extrusion foaming technology, providing long-term fire prevention, heat insulation and anti-scald protection for all high-risk wiring and pipeline systems.
Flame-Retardant Silicone Raw Material & Special Foaming Extrusion Process
Our flame retardant silicone foam tube uses imported high-purity flame retardant silicone base material, added with halogen-free environmental flame retardant additives, non-toxic, low smoke and no harmful precipitation, specially optimized for long-term high-temperature and fire-prone working environments. We adopt one-piece co-extrusion vulcanization foaming process to form uniform and fine closed-cell honeycomb pores inside the tube wall, with smooth inner and outer surfaces, no powder falling off and no delamination after long-term bending and extrusion. The foaming density can be adjusted according to customer safety and heat insulation requirements to balance softness, resilience and fire resistance.
This professional flame retardant silicone foam tube has an ultra-wide operating temperature range of -60℃ to 280℃, maintaining stable softness, elasticity and flame retardant performance under long-term high-temperature baking, cold-hot alternating cycles and steam environment, without hardening, cracking, shrinkage or failure of fire resistance. It has excellent chemical inertness, resisting corrosion from engine oil, battery electrolyte, weak acid and alkaline cleaning agents, and outstanding UV and ozone aging resistance. All products fully comply with RoHS 2.0, REACH, UL 94 V-0 flame retardant standard, and can provide complete SGS and Intertek third-party fire safety test reports to meet global industrial high-safety production standards.
Core Performance Advantages Focused on Fire Safety Protection
Targeted at the fire hazard pain points of high-temperature pipelines and high-voltage harnesses, our flame retardant silicone foam tube upgrades flame retardant performance on the basis of complete thermal insulation and buffer functions, breaking through the safety defects of ordinary plastic and rubber foam sleeves:
-
UL 94 V-0 Highest Grade Flame Retardancy: Self-extinguishes within 10 seconds after leaving open flame, no molten dripping, no toxic dense smoke release, effectively isolate flame propagation, prevent fire spread along wires and pipelines, greatly reduce equipment fire accident risks.
-
Efficient Heat Insulation & Anti-Scald: Dense closed-cell structure forms stable air insulation layer, low thermal conductivity effectively lock internal heat, reduce pipeline surface temperature, avoid operation scald accidents, and prevent surrounding plastic and electronic components from overheating aging.
-
Wide High & Low Temperature Resistance: Stable long-term use at -60℃~280℃, adapt to outdoor low-temperature storage, continuous high-temperature heat radiation and frequent cold-hot cycle working conditions, flame retardant performance will not attenuate after repeated temperature impact.
-
Waterproof & Dustproof Sealing Barrier: Compact closed-cell pore structure blocks moisture, water vapor and fine dust penetration, avoid internal wire short circuit and pipeline corrosion caused by damp environment, maintain stable insulation and fire resistance in humid scenes.
-
Flexible Shock Absorption & Wear Resistance: Soft and high elastic texture, can be bent arbitrarily to adapt to complex equipment wiring layout; porous foam layer buffers vibration and friction impact during operation, protect internal wires and pipelines from scratch and collision damage.

Precautions for Use
To fully maintain the flame retardant, heat insulation and shock absorption performance of flame retardant silicone foam tube and extend its service life, please abide by the following operation specifications during installation, use and storage:
-
Before installation, thoroughly wipe the surface of wrapped pipelines and wires to keep dry, smooth and free of oil, dust and burr impurities, ensure tight fitting and stable fire protection and heat insulation effect.
-
Avoid excessive stretching and sharp metal scratching during installation, prevent damage to the internal closed-cell pore structure of tube wall and reduce flame retardant and heat insulation efficiency.
-
Control the bending radius reasonably during wiring, avoid long-term over-compression, so as not to cause permanent deformation and lose tight wrapping and fire resistant performance.
-
Store the product in a cool, dry and ventilated warehouse before installation, keep away from high-temperature heat sources, open flames and corrosive industrial chemicals to prevent premature aging and attenuation of flame retardant performance.
-
Select the corresponding wall thickness, density and UL flame retardant grade according to the actual pipeline operating temperature and fire risk level to match the required fire safety protection standard.
