When fluid transfer applications require enhanced abrasion resistance, structural stability, and protection against external damage, outer braided silicone tubing is the ideal choice. Tengye delivers premium outer braided silicone tubing—combining a high-performance silicone inner tube with a dense outer braided layer—to meet the rigorous demands of global industries, from automotive and industrial machinery to food processing and medical sectors.
Premium Structure: Silicone Core + Outer Braided Reinforcement
Our outer braided silicone tubing features a two-layer design optimized for functionality and durability. The inner layer is crafted from high-purity silicone (food-grade, industrial-grade, or medical-grade options available) with a smooth surface (Ra ≤ 0.08μm) to ensure unobstructed fluid flow, minimize residue buildup, and enable easy cleaning. The outer layer is made of high-strength fibers—polyester, nylon, aramid, or stainless steel wire—woven tightly around the silicone core to form a protective mesh.
This outer braided layer serves multiple critical purposes: it shields the silicone core from abrasion, cuts, and friction caused by contact with machinery, pipes, or harsh environments; prevents the silicone tube from expanding or kinking under pressure; and enhances overall tensile strength by up to 4x compared to non-braided silicone tubing. 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 for traceability.
Precision Production: Ensuring Uniformity & Performance
Our specialized production workflow guarantees consistent quality across every meter of outer braided silicone tubing, with strict control over both the silicone core and outer braid:
-
Silicone Core Extrusion: High-purity silicone is mixed with application-specific additives (flame retardants, UV stabilizers, or biocompatible agents) and extruded into a uniform inner tube. We use platinum vulcanization for odorless, non-toxic results—critical for food, beverage, and medical applications—to avoid harmful byproducts.
-
Precision Outer Braiding: Computer-programmed braiding machines wrap the silicone core with high-strength fibers at a controlled density (80-95% coverage) and tension. This ensures the braid adheres tightly to the silicone surface, forming a seamless protective layer without loose threads or uneven gaps. For ultra-abrasive or high-pressure scenarios, stainless steel wire braiding is available to further boost durability.
-
Post-Braiding Curing & Finishing: The braided tubing undergoes a secondary curing process to enhance the bond between the silicone core and outer braid, preventing delamination. We then trim excess threads, check for dimensional accuracy, and conduct performance tests to ensure the tubing meets specified standards.
-
Multi-Dimensional Quality Inspection: Each batch is tested for pressure resistance (working pressure 1.5-8MPa, burst pressure 3x working pressure), abrasion resistance (≥50,000 cycles without core damage), thermal stability (-60℃ to 230℃), and dimensional accuracy (±0.1mm for critical sizes). Food and medical grades undergo additional migration and sensory tests to ensure safety.
Key Traits & Performance Advantages
Our outer braided silicone tubing stands out for its balanced combination of protection, flexibility, and durability:
-
Superior Abrasion Resistance: The outer braided layer acts as a barrier against scratches, cuts, and wear, extending the tubing’s service life by 3-5x compared to non-braided silicone tubes—ideal for high-friction environments like industrial machinery or automotive engine compartments.
-
Enhanced Pressure & Structural Stability: Resists tube expansion and kinking under pressure, maintaining flow integrity. Working temperature range of -60℃ to 230℃ (-76°F to 446°F) with short-term tolerance up to 260℃ for high-temperature sterilization (compatible with SIP/CIP systems).
-
Flexibility with Protection: Retains silicone’s inherent flexibility for easy installation in tight spaces, while the outer braid provides rigid structural support—eliminating the trade-off between flexibility and durability.
-
Versatile Compatibility: Resists UV radiation, ozone, mild acids, alkalis, and industrial oils. Food-grade and medical-grade options ensure safety for direct contact with edibles, pharmaceuticals, and bodily fluids.
Industry-Specific Applications
Our outer braided silicone tubing is tailored to solve unique challenges across diverse sectors:
-
Automotive & EVs: Engine coolant hoses, turbocharger lines, and fuel system tubes. The outer braid resists under-hood abrasion and heat, while the silicone core handles extreme temperature fluctuations.
-
Industrial Machinery: Hydraulic lines, coolant transfer tubes, and chemical hoses. Abrasion resistance protects against contact with metal parts, while pressure stability ensures reliable operation in heavy-duty equipment.
-
Food & Beverage Processing: Transfer lines for edible oil, milk, juice, and syrup. FDA/LFGB compliance ensures safety, and the smooth silicone core prevents residue buildup for easy cleaning.
-
Medical & Pharmaceutical: Infusion system tubes, bioreactor lines, and sterilization equipment hoses. USP Class VI certification ensures biocompatibility, and the outer braid protects against damage during handling and sterilization.
-
Marine & Offshore: Seawater transfer hoses and offshore equipment lines. The outer braid resists saltwater corrosion and abrasion from marine debris, while the silicone core maintains flexibility in harsh coastal environments.
