In new energy thermal management, automotive high-voltage pipelines, industrial heating equipment and catering machinery, exposed high-temperature pipelines and wiring harnesses face severe heat loss, surface overheating, personnel scalding and component thermal aging problems. Thermal preservation foamed silicone tube is a professional flexible tubular thermal insulation material developed for constant temperature maintenance and heat isolation scenarios. It adopts uniform closed-cell foaming structure to lock static air inside the tube wall, form an efficient thermal barrier, realize dual functions of heat preservation and heat insulation, and greatly reduce equipment energy consumption. Tengye supplies high-performance thermal preservation foamed silicone tubes, manufactured with high-purity silicone raw materials and integrated extrusion foaming technology, providing long-term stable anti-scald, heat-locking and flame-retardant protection for all kinds of 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, optional halogen-free flame-retardant formula, non-toxic, low-smoke and environmentally friendly, specially optimized for long-term constant temperature pipeline working conditions. We adopt one-step closed-cell extrusion foaming vulcanization process to form uniform and delicate honeycomb pores inside the tube wall, with smooth and compact inner and outer surfaces, no pore leakage, no powder shedding, and stable thermal conductivity for long-term continuous use. The foaming density can be adjusted according to customer insulation requirements to balance softness and heat preservation efficiency.
This professional thermal preservation foamed silicone tube has an ultra-wide operating temperature range of -60℃ to 280℃, maintaining stable softness, elasticity and thermal insulation performance under long-term high-temperature baking, cold-hot alternating cycles and steam environment, without hardening, cracking, shrinkage or deformation. It has excellent weather resistance, ozone aging resistance and chemical resistance, resisting corrosion from oil, weak acid and alkali cleaning agents, and will not swell or degrade after long-term contact with heat medium. All products fully comply with RoHS 2.0, REACH, UL 94 V-0 flame retardant standards, and can provide complete SGS and Intertek third-party test reports to meet global industrial equipment safety standards.
Core Performance Advantages for Thermal Preservation & Heat Insulation
Targeted at the pain points of serious heat loss, easy scalding and rapid aging of uninsulated pipelines, our thermal preservation foamed silicone tube breaks through the performance limitations of ordinary solid silicone tubes and plastic foam sleeves, with all-round optimized functional advantages:
-
Efficient Thermal Preservation & 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 preservation in winter and heat isolation in summer, reduces equipment energy consumption by more than 30%.
-
Anti-Scald Surface Protection: The foam buffer layer greatly reduces the surface temperature of high-temperature pipelines, avoids scald accidents during equipment operation and maintenance, and isolates high-temperature heat radiation to prevent surrounding plastic and electronic parts from overheating aging.
-
Wide High & Low Temperature Resistance: Stable long-term use at -60℃~280℃, adapt to freezing storage, normal temperature circulation and continuous high-temperature heating working conditions, no attenuation of thermal insulation performance after repeated temperature cycles.
-
UL 94 V-0 Top-Tier Flame Retardancy: Flame-retardant grade reaches UL 94 V-0, self-extinguishes quickly after leaving fire, no molten dripping and no release of toxic smoke, effectively inhibits flame spread and eliminates fire risks caused by pipeline high temperature.
-
Flexible Shock Absorption & Wear Resistance: Soft and high elasticity, arbitrary bending to adapt to complex pipeline layout; porous structure absorbs vibration and friction impact during equipment operation, protects 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 maintain tight fitting with the pipeline, and will not lose thermal preservation effect due to long-term extrusion.
-
Chemically Inert & Long Service Life: Neutral material, no chemical corrosion to metal, plastic, wire insulation and other contact materials; strong anti-ultraviolet and anti-aging performance, stable performance for 8-12 years in indoor and outdoor environments.

Precautions for Use
To fully maintain the thermal preservation, heat insulation and flame-retardant performance of thermal preservation foamed silicone 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 the wrapped pipeline to keep it dry, smooth and free of oil, dust and burr impurities, to ensure tight fitting and stable heat locking effect.
-
Avoid excessive stretching and sharp metal scratching during installation to prevent damage to the internal closed-cell pore structure of the tube wall and reduce thermal 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 heat preservation 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 performance attenuation.
-
Select the corresponding wall thickness, density and flame retardant grade according to the actual pipeline operating temperature and use environment to match the required thermal preservation effect.
