When fluid transfer applications involve extreme heat, high pressure, and harsh environmental conditions, high-temperature braided silicone tubing stands as the industry’s reliable solution. Tengye delivers premium high-temperature braided silicone tubing—engineered with a heat-resistant silicone core and reinforced braided layer—to meet the rigorous demands of global industries, from industrial ovens and automotive engine compartments to aerospace and pharmaceutical sterilization systems.
Premium Structure: High-Temp Silicone Core + Reinforced Braided Layer
Our high-temperature braided silicone tubing features a two-layer design optimized for extreme thermal performance and structural durability. The inner core is crafted from high-grade heat-resistant silicone, formulated with special thermal stabilizers and reinforcing additives to withstand prolonged exposure to high temperatures. This silicone core maintains elasticity and integrity at temperatures up to 260℃ (500°F) for continuous use, with short-term tolerance up to 300℃ (572°F) for intermittent high-heat scenarios, outperforming standard silicone tubing by 40℃ in maximum continuous service temperature.
The outer reinforced braided layer is made of high-strength fibers—aramid, polyester, or stainless steel wire—woven tightly around the silicone core. This layer not only enhances abrasion resistance and tensile strength (up to 4x vs. non-braided high-temp silicone tubing) but also prevents tube expansion and kinking under high heat and pressure. Every batch adheres to global standards, including FDA 21 CFR 177.2600 (food contact), USP Class VI (medical use), RoHS 2.0, and UL 94 V-0 (flame retardancy), with third-party SGS/Intertek test reports available to verify thermal stability and safety.
Precision Production: Thermal Stability & Performance Assurance
Our specialized production workflow ensures consistent high-temperature performance, braid uniformity, and structural integrity across every meter of tubing, with strict control over both the heat-resistant core and reinforced layer:
-
High-Temp Silicone Formulation & Core Extrusion: We blend high-purity silicone with thermal stabilizers, anti-aging agents, and application-specific additives (flame retardants, biocompatible components) to create a heat-resistant compound. The mixture is extruded into a uniform inner tube using precision equipment, with a smooth surface (Ra ≤ 0.08μm) to minimize fluid residue and enable easy cleaning. Platinum vulcanization is used for odorless, non-toxic results—critical for food, medical, and pharmaceutical applications.
-
Precision Braiding for Heat Environments: Computer-programmed braiding machines wrap the silicone core with heat-resistant fibers at a controlled density (80-95% coverage) and tension. Aramid fibers are preferred for high-heat industrial applications due to their exceptional thermal stability, while stainless steel wire braiding is available for ultra-high pressure and extreme heat scenarios. The braid is engineered to bond tightly with the silicone core, preventing delamination even under repeated thermal cycles.
-
Thermal Curing & Finishing: The braided tubing undergoes a specialized high-temperature curing process to lock in thermal stability and enhance the bond between the silicone core and braided layer. This step ensures the tubing retains its properties after prolonged exposure to high heat, with no cracking, hardening, or performance degradation. Excess threads are trimmed, and dimensional accuracy is verified before performance testing.
-
Multi-Dimensional Quality Inspection: Each batch is subjected to rigorous thermal tests, including continuous exposure at 260℃ for 1000 hours and thermal cycle testing (-60℃ to 260℃) to ensure stability. Additional tests include pressure resistance (working pressure 1.5-8MPa, burst pressure 3x working pressure), abrasion resistance (≥50,000 cycles without core damage), and dimensional accuracy (±0.1mm for critical sizes). Food and medical grades undergo extra migration and sensory tests to ensure safety.
Key Traits & Performance Advantages
Our high-temperature braided silicone tubing stands out for its exceptional thermal resistance, durability, and versatility in harsh environments:
-
Extreme Heat Tolerance: Continuous service temperature range of -60℃ to 260℃ (-76°F to 500°F), with short-term tolerance up to 300℃. Maintains elasticity and sealing performance after prolonged high-heat exposure, avoiding hardening, cracking, or brittleness.
-
Reinforced Durability & Pressure Resistance: The braided layer enhances abrasion, cut, and pressure resistance, extending service life by 3-5x vs. non-braided high-temp silicone tubing. Resists tube expansion and kinking under high heat and pressure, ensuring consistent fluid flow.
-
Thermal Stability & Anti-Aging: Formulated with thermal stabilizers and anti-aging additives to resist UV radiation, ozone, and high-heat oxidation. Maintains performance integrity for 5-8 years in continuous high-temperature service.
-
Multi-Industry Compatibility: Resists mild acids, alkalis, industrial oils, and solvents. Compatible with SIP/CIP sterilization systems (121℃-134℃ steam) for medical and food applications, with no toxic emissions under high heat.
