In new energy thermal management systems, new energy vehicle pipelines, industrial heating machinery and catering processing equipment, exposed high-temperature fluid pipelines and high-voltage wiring harnesses suffer severe heat loss, surface overheating, operator scalding and component thermal aging. Thermal preservation foamed silicone tube is a flexible tubular thermal insulation material specially developed for constant temperature maintenance and thermal barrier scenes. Its uniform closed-cell foamed structure locks static air inside tube wall to form an efficient thermal isolation layer, realizing dual functions of heat retention and heat insulation, and greatly cutting equipment energy consumption. Tengye supplies high-performance thermal preservation foamed silicone tubes produced by high-purity silicone raw materials and one-step integrated extrusion foaming technology, providing long-term anti-scald, heat-locking and flame-retardant protection for all fluid pipelines and wiring harness systems.
Premium Silicone Raw Material & Thermal Insulation Optimized Foaming Process
Our thermal preservation foamed silicone tube adopts imported high-purity industrial silicone raw materials, with optional halogen-free low-smoke flame retardant formula, non-toxic and eco-friendly, specially optimized for long-term constant temperature pipeline working conditions. We adopt integrated closed-cell extrusion vulcanization foaming craft to form uniform honeycomb fine pores inside tube wall, smooth and compact inner & outer surfaces without powder shedding or pore leakage, stable thermal conductivity for continuous long-term service. Foaming density can be adjusted according to customer insulation demands to balance softness and heat preservation efficiency.
This professional thermal preservation foamed silicone tube owns ultra-wide operating temperature range of -60℃ to 280℃, keeping stable softness, elasticity and thermal insulation performance under long-term high-temperature baking, cold-hot alternating cycles and steam environments, no hardening, cracking, shrinkage or deformation. It features excellent weather resistance, ozone aging resistance and chemical inertness, resisting erosion of oil, weak acid and alkaline cleaning agents, no swelling or degradation after long-term contact with thermal medium. All products fully comply with RoHS 2.0, REACH, UL 94 V-0 flame retardant standards, complete SGS & Intertek third-party test reports are available to meet global industrial equipment safety standards.
Core Performance Advantages for Thermal Preservation & Heat Insulation
Aiming at industry pain points of serious heat loss, easy scalding and rapid aging of bare pipelines, our thermal preservation foamed silicone tube overcomes performance defects of solid silicone tubes and ordinary plastic foam sleeves, with comprehensive optimized functional advantages:
-
Efficient Thermal Preservation with Low Thermal Conductivity: Dense closed-cell structure locks static air, thermal conductivity ≤0.06W/m·K, effectively blocks internal heat outward loss and external high-temperature heat invasion, realizes heat retention in winter and heat insulation in summer, reduces equipment energy consumption by over 30%.
-
Anti-Scald Surface Protection: Foamed buffer layer sharply lowers surface temperature of high-temperature pipelines, avoids scald accidents during equipment operation and maintenance, and isolates high-temperature heat radiation to prevent peripheral plastic and electronic parts from overheating aging.
-
Wide High & Low Temperature Tolerance: Stable long-term service at -60℃~280℃, adapts to freezing storage, normal temperature circulation and continuous high-temperature heating working conditions, thermal insulation performance will not decay after repeated temperature cycles.
-
UL 94 V-0 Top-Tier Flame Retardancy: Reaches UL 94 V-0 highest flame retardant grade, self-extinguishes rapidly after leaving open flame, no molten dripping and no toxic smoke release, effectively inhibits flame spread and eliminates fire risks triggered by pipeline high temperature.
-
Flexible Shock Absorption & Wear Resistance: Soft and high elastic, arbitrarily bendable to fit complex pipeline layout; porous structure absorbs vibration and friction impact during equipment operation, protecting internal pipelines and wiring harnesses from abrasion and collision damage.
-
Low Compression Set & Long-Lasting Resilience: Compression set ≤5%, no permanent deformation after long-term clamping and wrapping, always maintains tight fit with pipelines and will not lose thermal preservation effect from long-term extrusion.
-
Chemically Inert & Long Service Life: Neutral material, no chemical corrosion to metal, plastic, wire insulation and other contact materials; strong UV and anti-aging performance, stable performance for 8-12 years under indoor and outdoor environments.

Precautions for Use
To fully retain thermal preservation, thermal insulation and flame retardant performance of thermal preservation foamed silicone tube and extend its service life, please follow below operation specifications during installation, use and storage:
-
Before installation, thoroughly wipe wrapped pipeline surfaces to keep dry, smooth and free of oil, dust and burr impurities, to ensure tight fit and stable heat locking effect.
-
Avoid excessive stretching and sharp metal scratching during installation to prevent damage to tube wall internal closed-cell pore structure and reduce thermal insulation efficiency.
-
Reasonably control bending radius during wiring, avoid long-term over-compression to prevent permanent deformation and loss of tight wrapping and heat preservation performance.
-
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 attenuation.
-
Select corresponding wall thickness, density and flame retardant grade according to actual pipeline operating temperature and service environment to match required thermal preservation effect.
