In new energy thermal management, new energy vehicle high-voltage systems, industrial high-temperature equipment and electrical control cabinets, internal pipelines and high-voltage harnesses face dual severe threats of long-term ultra-high temperature radiation and fire risks caused by short circuits. High temperature & flame retardant silicone foam tube is a high-performance tubular protective material specially developed for extreme high-temperature and high fire safety working conditions. It integrates upgraded high-temperature resistant silicone matrix and halogen-free flame retardant formula, matched with closed-cell foaming structure to realize triple functions of high-temperature resistance, efficient heat insulation and flame blocking. Tengye produces premium high temperature flame retardant silicone foam tubes via integrated co-extrusion foaming vulcanization process, providing long-term stable anti-scald, heat preservation and fire isolation protection for all high-temperature flammable pipeline and wiring systems.
High-Temp Flame-Retardant Silicone Raw Material & Special Foaming Extrusion Process
Our high temperature flame retardant silicone foam tube adopts imported high-purity ultra heat-resistant silicone base material, compounded with halogen-free low-smoke environmental flame retardant additives, non-toxic, no harmful volatile precipitation, specially optimized for long-term continuous high-temperature and fire-prone complex environments. We adopt one-piece closed-cell extrusion foaming integrated molding technology to form uniform and delicate honeycomb pore structure inside tube wall, smooth and compact inner and outer skin without powder shedding, layer separation and pore breakage after long-term bending and extrusion. Foaming density and hardness can be adjusted according to customer heat insulation and fire safety demands to balance soft wrapping performance, high-temperature stability and flame retardant efficiency.
This professional dual-performance silicone foam tube owns an ultra-wide operating temperature range of -60℃ to 280℃, capable of stable long-term service under continuous high-temperature baking, cold-hot alternating cycles and steam immersion, no hardening, cracking, shrinkage, softening or failure of flame retardant performance after repeated thermal impact. It features excellent chemical inertness, resisting corrosion from engine oil, battery electrolyte, weak acid and alkaline industrial cleaning agents, as well as outstanding UV and ozone aging resistance, adapting to indoor and outdoor long-term harsh operation. All products fully comply with RoHS 2.0, REACH, UL 94 V-0 top flame retardant standard, complete SGS and Intertek third-party high-temperature fire safety test reports can be provided for customer verification, meeting global industrial high-standard safety specifications.
Core Dual-Core Performance Advantages: High Temp Resistance + Flame Retardancy
Aiming at the dual pain points of ordinary foam tubes failing at high temperature and poor fire blocking effect, our high temperature flame retardant silicone foam tube realizes comprehensive performance upgrade, perfectly matching extreme high-temperature safety protection scenarios:
-
Ultra-Wide High & Low Temperature Resistance: Stable long-term use at -60℃~280℃, short-term instantaneous temperature resistance up to 300℃, far exceeding the heat resistance limit of ordinary silicone foam tubes. It maintains stable elasticity and structural integrity under long-term heat radiation, no performance attenuation, suitable for oven, engine compartment and other continuous high-temperature working areas.
-
UL 94 V-0 Top-Grade Flame Retardancy: Self-extinguishes within 10 seconds after leaving open flame, no molten dripping, no dense toxic smoke release, effectively cuts off flame spread along pipelines and wires, avoids fire chain reaction caused by equipment overheating and short circuit, greatly reducing industrial fire hazards.
-
Efficient Thermal Insulation & Anti-Scald Protection: Dense closed-cell air insulation layer with low thermal conductivity ≤0.06W/m·K, effectively locks internal heat and isolates external high-temperature heat invasion, reduces pipeline surface temperature to prevent maintenance scald accidents, and avoids surrounding plastic and electronic components from thermal aging failure.
-
Waterproof & Dustproof Insulation Barrier: Compact foam skin structure blocks moisture, water vapor and fine dust penetration, prevents internal wire short circuit and pipeline metal corrosion in humid environment, maintains stable insulation, high-temperature and flame retardant performance all year round.
-
Flexible Shock Absorption & Wear Resistance: Soft high-elastic texture, arbitrarily bendable to adapt to complex equipment pipeline layout; porous buffer layer absorbs vibration and friction impact during equipment operation, protects internal wires and fluid pipelines from scratch, collision and abrasion damage.
-
Low Compression Set & Long-Lasting Stability: Compression set ≤5%, no permanent deformation after long-term wrapping and clamping, always keeps tight fitting with pipelines, high-temperature resistance and flame retardant functions will not fail due to long-term extrusion deformation.
-
Non-Corrosive & Ultra-Long Service Life: Neutral chemically inert material, no chemical reaction with metal, plastic, wire insulation and other contact materials; strong anti-oxidation and weather resistance, stable comprehensive performance for 8-12 years under indoor and outdoor alternating temperature environments.

Precautions for Use
To fully retain the dual core performance of high temperature resistance and flame retardancy, as well as thermal insulation and shock absorption effects, and extend service life, please follow standardized operation specifications during installation, use and storage:
-
Before installation, thoroughly wipe wrapped pipeline and wire surfaces to keep dry, smooth and free of oil, dust and burr impurities, ensure tight fit and stable high-temperature fire protection effect.
-
Avoid excessive stretching and sharp metal scratching during installation to prevent damage to tube wall internal closed-cell pore structure, resulting in attenuation of heat insulation, high temperature and flame retardant performance.
-
Reasonably control bending radius during wiring, avoid long-term over-compression to prevent permanent deformation and loss of tight wrapping and core safety functions.
-
Store products in cool, dry and ventilated warehouse before installation, keep away from high-temperature heat sources, open flames and corrosive industrial chemicals to avoid premature aging and performance decline.
-
Select corresponding wall thickness, density and flame retardant grade according to actual pipeline long-term operating temperature and fire risk level to match required high-temperature fire safety protection standard.
