Core Performance & Structural Advantages
Adopting dense and uniform closed-cell foam structure, smooth inner and outer tube walls, consistent dimensional tolerance and ultra-high flexibility, this silicone foam tube features soft touch, strong resilience and no permanent deformation. It is easy to sleeve and fit various pipelines, wires and equipment profiles without scratching or extruding protected parts. Optimized for long-term high-temperature working conditions, it solves the defects of ordinary rubber tubes and common foam tubes such as high-temperature softening, aging cracking, poor heat insulation and easy combustion, with outstanding comprehensive performance:
-
Superior Ultra-Wide Temperature Resistance: Supports long-term stable operation at -60℃ to 250℃, and withstands instantaneous extreme high temperature up to 300℃. It remains soft and flexible at low temperatures without embrittlement or cracking, and does not soften, deform, melt or release volatile harmful substances under continuous high temperature. It effectively blocks heat conduction, reduces surface temperature of equipment and avoids high-temperature aging damage of peripheral components.
-
UL94 V-0 Grade Flame Retardant Safety: Formulated with halogen-free environmental flame retardant additives, it meets strict UL94 V-0 flame retardant standard. It achieves rapid self-extinguishing without molten dripping and low toxic smoke emission during combustion, forming an effective fire barrier. It can prevent flame spreading along pipelines and wiring harnesses, greatly reducing fire risks in high-temperature equipment rooms and vehicle cabin environments.
-
Closed-Cell Waterproof & Dustproof Sealing: The compact closed-cell structure delivers excellent waterproof, dustproof and moisture-proof performance. It can effectively isolate external rainwater, humid air, dust and corrosive gas penetration, prevent pipeline surface corrosion, circuit short circuit and poor contact failure caused by moisture invasion, and maintain clean and dry internal protection environment.
-
High Resilience & Shock Absorption Buffering: With soft elastic structure and compression set ≤7%, it can absorb most external vibration and impact energy. It effectively buffers friction, collision and extrusion between pipelines and equipment during equipment operation and vehicle driving, protecting wiring harnesses and tubular parts from mechanical damage and wear.
-
Excellent Electrical Insulation Performance: With volume resistivity ≥10¹⁴Ω·cm, it has stable and reliable electrical insulation capacity. It can isolate current leakage, prevent short circuit and electromagnetic interference, effectively protect high-temperature wiring harnesses, connectors and electrical components, and improve the overall electrical safety of equipment.
-
Anti-Aging & Long Service Life: Added with anti-UV, anti-ozone and high-temperature anti-aging ingredients, it has strong weather resistance. It can resist long-term high-temperature baking, outdoor sunlight and harsh environmental erosion, avoiding hardening, yellowing and cracking. It maintains stable physical and chemical properties for 8–10 years, matching the service life of industrial and vehicle equipment.
-
Precision Customization & Easy Installation: Supports customized inner diameter, outer diameter, tube wall thickness, length and color according to customer requirements. Dimensional tolerance is controlled within ±0.05mm to ensure precise sleeving fit. The soft and bendable tube body is easy to cut, sleeve and fix, greatly improving on-site construction and assembly efficiency.
-
Eco-Friendly Material Compatibility: Halogen-free, non-toxic, odorless and heavy metal-free, fully compliant with RoHS and REACH environmental protection regulations. It has good compatibility with metal pipelines, plastic wires, rubber accessories and electronic components, no chemical corrosion and no adverse reaction.

Special High-Temperature Formula Screening: Adopt platinum-cured silicone raw materials and high-temperature resistant flame-retardant formula, all raw materials pass high-temperature aging test, flame retardant test and environmental protection detection to adapt to long-term high-heat working conditions.
-
Extrusion Foaming Precision Process: Adopt closed-cell continuous extrusion foaming technology to ensure uniform pore distribution, smooth tube wall and consistent thickness, avoiding local performance difference.
-
Multi-Dimensional Performance Testing: Each batch undergoes strict tests including high-temperature endurance test, flame retardant test, insulation test, compression resilience test, aging resistance test and dimensional calibration, with factory qualification rate up to 99.8%.
Precautions
1. Select matching inner diameter and wall thickness specifications according to the outer diameter of the protected pipeline and wiring harness to ensure tight sleeving and avoid loose falling off or excessive extrusion deformation.
2. Do not stretch, twist or pull the tube body violently during installation, so as not to damage the internal closed-cell structure and reduce heat insulation and flame retardant performance.
3. Avoid long-term direct contact with strong acid, strong alkali and corrosive solvents to prevent material deterioration and performance attenuation.
4. Store in dry, cool and ventilated environment, keep away from open fire and high-temperature heat sources, and avoid long-term heavy pressure stacking.
5. This product is suitable for conventional high-temperature insulation protection; do not use it beyond the rated temperature range for a long time.
6. Check the tube body regularly during equipment operation, and replace it in time if obvious aging, cracking and hardening occur.
