When fluid transfer in food, beverage, or pharmaceutical industries demands uncompromising safety and pressure resistance, food-grade silicone braided tubing becomes the gold standard. Tengye delivers premium food-grade silicone braided tubing—combining strict food safety compliance with a reinforced braided structure to meet global hygiene and performance requirements.
Premium Materials: Safety & Strength at the Core
Our food-grade silicone braided tubing is crafted from high-purity food-grade silicone raw material (free of phthalates, BPA, and heavy metals) paired with a reinforced braided layer of high-strength polyester or nylon fibers. Every batch undergoes rigorous safety and quality tests: material purity checks to ensure compliance with global food contact standards, braid uniformity assessments for consistent pressure resistance, and sensory evaluations to confirm no odor or taste transfer. This premium combination ensures the tubing is safe for direct food contact while withstanding high pressures and repeated cleaning cycles.
We strictly adhere to international food safety benchmarks, including FDA 21 CFR Part 177.2600 (US), EU No 10/2011, German LFGB, and China’s GB 4806.11-2024 . All products are manufactured in ISO 14644-1 Class 1000 cleanrooms, where airborne particles and microorganisms are strictly controlled to avoid contamination during production . For pharmaceutical applications, we offer formulations that meet USP Class VI biocompatibility standards .
Precision Production: Braided Reinforcement & Hygiene Control
Our specialized production workflow ensures both food safety and structural integrity, with hygiene as a priority at every step:
-
Inner Tube Extrusion: Food-grade silicone is extruded into a smooth inner tube (1-2mm wall thickness for optimal support) . The inner surface is mirror-polished (Ra ≤ 0.08μm) to minimize food residue and enable easy cleaning .
-
Reinforced Braiding: High-strength polyester or nylon fibers are precisely woven around the inner tube using computer-programmed braiding machines. This layer boosts pressure resistance—standard models withstand 12-38 bar, while custom ultra-high-pressure versions reach up to 150 bar (15MPa) with 4x safety redundancy .
-
Outer Tube Coating: A second layer of food-grade silicone is extruded over the braided layer, ensuring a seamless, contamination-resistant exterior. We optimize outer tube thickness to eliminate air bubbles and maintain a smooth surface .
-
Platinum Vulcanization & Curing: The tubing undergoes platinum vulcanization (instead of traditional peroxide vulcanization) for odorless, non-toxic results, then cured in temperature-stabilized ovens to lock in safety and structural properties .
-
Multi-Dimensional Quality Inspection: Each batch undergoes migration testing (per FDA/EU standards), pressure burst tests, dimensional checks, and sensory evaluations. For critical applications, third-party testing (SGS/Intertek) is provided with traceable reports .
Key Traits & Performance Specifications
Our food-grade silicone braided tubing stands out for its safety, durability, and versatility:
-
Food Safety Compliance: 100% non-toxic, odorless, and tasteless—no migration of harmful substances into fluids. Passes rigorous extraction tests (70℃, 24-hour soak in water, 3% acetic acid, 50% ethanol) with volatile substances ≤ 0.5% .
-
Superior Pressure & Temperature Resistance: Burst pressure ≥ 15MPa (standard models), with working temperatures from -60℃ to 200℃ (-76°F to 392°F)—short-term tolerance up to 250℃ for high-temperature sterilization .
-
Hygiene & Cleanability: Smooth inner wall prevents residue buildup; compatible with CIP (Clean-in-Place) and SIP (Sterilize-in-Place) systems, including 121℃ high-temperature steam sterilization .
-
Durable & Flexible: Resists UV, ozone, and mild acids/alkalis (pH 1-14); maintains flexibility after 100+ cleaning cycles without hardening or cracking . Withstands 100,000+ compression cycles for蠕动泵 (peristaltic pump) applications .
Versatile Applications Across Food & Related Industries
Our food-grade silicone braided tubing is tailored for hygiene-critical fluid transfer scenarios:
-
Food & Beverage Processing: Transfer of milk, edible oil, fruit juice, syrup, and beer. Ideal for filling lines, tank trucks, and mixing equipment—compatible with hot-fill (150℃) and cold-chain (-60℃) processes .
-
Dairy & Confectionery: Transport of raw milk, yogurt, and chocolate syrup. Smooth inner wall prevents bacterial growth, while heat resistance handles pasteurization (121℃) .
-
Pharmaceutical & Cosmetics: Transfer of medicinal liquids, herbal extracts, and cosmetic bases. USP Class VI certification ensures biocompatibility for pharmaceutical use .
-
Commercial Kitchens & Catering: Use in dishwashers, steam ovens, and beverage dispensers—resists high temperatures and frequent cleaning .
-
Food Packaging & Filling: Peristaltic pump tubing for precise filling of sauces, condiments, and baby food—maintains flow accuracy with minimal fatigue .
