In new energy systems, automotive equipment, household appliances and industrial machinery, internal pipelines and wiring harnesses face long-term high-temperature heat radiation, heat accumulation and thermal aging risks, which easily cause component performance degradation, shell overheating and even safety accidents. Heat insulation silicone foam tube is a professional flexible thermal insulation protective material specially developed for thermal barrier and constant-temperature protection scenarios. Adopting high-performance silicone foaming structure, it forms a stable air insulation layer to effectively block heat conduction, reduce surface temperature and isolate high-temperature interference. Tengye supplies high-quality heat insulation silicone foam tubes, manufactured with high-purity silicone raw materials and precision integrated foaming extrusion technology, providing long-term stable heat preservation, thermal insulation, flame-retardant and anti-aging protection for various industrial pipelines and wiring systems.
Premium Silicone Material & Thermal Insulation Optimized Process
Our heat insulation silicone foam tube adopts imported high-purity silicone raw materials, with halogen-free, low-smoke, non-toxic and environmentally friendly formula, specially optimized for long-term heat insulation and constant-temperature working conditions. We adopt one-piece extrusion closed-cell foaming technology to form uniform and dense internal pore structure, which perfectly balances soft flexibility, high resilience and excellent thermal insulation performance. The tube wall is smooth and compact without pores, cracks or uneven thickness, ensuring stable and consistent thermal barrier effect in long-term service.
This professional heat insulation silicone foam tube features an ultra-wide operating temperature range from -60℃ to 280℃, maintaining stable softness, toughness and physical properties under long-term high-temperature heat radiation and cold-hot alternating cycles, no hardening, cracking, shrinkage or deformation. It has outstanding thermal insulation, heat preservation, weather resistance and anti-aging performance, effectively slowing down heat loss and isolating external high-temperature heat transfer. All products fully comply with RoHS 2.0, REACH, UL 94 V-0 and other international industry certifications, with authoritative SGS and Intertek test reports available, meeting global industrial safety and environmental protection standards.
Core Performance Advantages for Thermal Insulation & Protection
Targeted at the heat dissipation, heat loss and high-temperature aging pain points of industrial pipelines and harnesses, our heat insulation silicone foam tube breaks through the limitations of ordinary protective sleeves, with fully optimized comprehensive performance:
-
Excellent Thermal Insulation & Heat Preservation: The dense closed-cell structure forms an efficient air thermal insulation layer, which greatly reduces heat conduction and heat radiation. It can effectively isolate high-temperature heat of internal pipelines and prevent external heat invasion, realizing dual effects of heat insulation in summer and heat preservation in winter, reducing equipment energy consumption.
-
Ultra-High Temperature Resistance: Stably resistant to long-term 280℃ high temperature, adapting to continuous heat baking and thermal cycle environment of mechanical equipment, without performance attenuation or structural damage, far exceeding the heat resistance of ordinary rubber and plastic sleeves.
-
Top-Tier Flame Retardancy: Meets UL 94 V-0 highest flame retardant standard, self-extinguishes rapidly after leaving fire, with no molten dripping and no toxic gas release. It effectively inhibits flame spread and avoids ignition risks of wires and pipelines caused by high temperature.
-
Flexible Buffering & Wear Resistance: Soft and highly flexible with good bending performance, suitable for complex wiring and pipeline bending layout. It buffers external friction, vibration and extrusion impact, protecting internal wires and pipelines from wear and structural damage.
-
Low Compression Set & Stable Resilience: Possesses excellent compression recovery capability, no permanent deformation after long-term extrusion and wrapping, maintaining tight fitting and stable thermal insulation effect for a long time, suitable for dynamic and static working environments.
-
Reliable Electrical Insulation: Excellent insulation performance, effectively isolating current and static interference, preventing short circuit, electric leakage and breakdown risks, improving the overall operational safety of electrical and pipeline systems.
-
Non-Corrosive & Long Service Life: The material is chemically inert and non-corrosive to metal, plastic, wire rubber skin and other contact materials, with strong oxidation resistance and aging resistance, supporting long-term indoor and outdoor industrial use.

Precautions for Use
To fully maintain the thermal insulation, heat preservation and flame-retardant performance of heat insulation silicone foam tube and extend its service life, please follow the standard guidelines during installation, use and storage:
-
Before installation, clean the surface of the protected pipeline and harness to keep it dry, smooth and free of oil, dust and impurities, ensuring tight fitting and stable thermal insulation effect.
-
Avoid excessive stretching, sharp scratching and violent tearing during installation to prevent damage to the foam tube wall and internal pore structure, which may reduce thermal insulation performance.
-
Control the bending radius reasonably and avoid long-term over-compression, so as not to cause permanent deformation and affect the wrapping and heat preservation effect.
-
Store the product in a cool, dry and ventilated environment before use, keep away from high-temperature heat sources, open flames and corrosive chemicals to prevent premature aging and performance degradation.
-
Select the corresponding tube specification and performance grade according to the actual working temperature and application scenario to ensure matching thermal insulation and safety protection effect.
