When fluid transfer in food, beverage, and pharmaceutical industries demands uncompromising hygiene, safety compliance, and structural durability, food-grade braided silicone tubing becomes the gold standard. Tengye delivers premium food-grade braided silicone tubing—combining a food-safe silicone core with a reinforced braided layer—to meet global food contact regulations and the rigorous demands of hygiene-critical applications.
Premium Structure: Food-Safe Silicone Core + Reinforced Braided Layer
Our food-grade braided silicone tubing features a two-layer design optimized for safety, hygiene, and performance. The inner core is crafted from high-purity food-grade silicone, free of BPA, phthalates, heavy metals, and harmful additives. It boasts a mirror-smooth surface (Ra ≤ 0.08μm) to minimize food residue buildup, prevent bacterial growth, and enable easy cleaning—critical for maintaining hygiene in food processing workflows. This silicone core is formulated to be odorless, tasteless, and non-toxic, ensuring no migration of harmful substances into fluids even under high temperatures or prolonged contact.
The outer reinforced braided layer is made of high-strength, food-safe polyester or nylon fibers, woven tightly around the silicone core. This layer enhances tensile strength by up to 4x compared to non-braided food-grade silicone tubing, resists tube expansion and kinking under pressure, and protects the silicone core from abrasion during handling and installation. Every batch strictly adheres to global food safety standards, including FDA 21 CFR 177.2600 (US), EU No 10/2011, German LFGB, and China’s GB 4806.11-2024, with third-party SGS/Intertek test reports available to verify compliance. Production takes place in ISO 14644-1 Class 1000 cleanrooms to avoid contamination, ensuring the highest hygiene standards.
Precision Production: Hygiene Control & Performance Assurance
Our specialized production workflow prioritizes food safety and hygiene at every step, while ensuring consistent braid uniformity and structural integrity across every meter of tubing:
-
Food-Grade Silicone Formulation & Core Extrusion: High-purity food-grade silicone is mixed with food-safe additives (thermal stabilizers, UV protectants) and extruded into a uniform inner core using precision equipment. We use platinum vulcanization instead of peroxide vulcanization to eliminate harmful byproducts, ensuring the tubing is safe for direct food contact and free of unpleasant odors or tastes.
-
Food-Safe Braiding Application: Computer-programmed braiding machines wrap the silicone core with food-grade polyester or nylon fibers at a controlled density (80-95% coverage) and tension. The braiding process is conducted in a dust-free environment to prevent contamination, with strict quality checks to ensure no loose threads or uneven gaps that could harbor bacteria.
-
Integrated Curing & Bonding: The braided tubing undergoes a controlled curing process to enhance the bond between the silicone core and braided layer, preventing delamination. The curing temperature and time are optimized to retain the silicone’s food-safe properties and ensure the surface remains smooth and easy to clean. Slow cooling avoids cracking or hardening, preserving flexibility.
-
Multi-Dimensional Quality & Hygiene Inspection: Each batch is subjected to rigorous tests, including migration testing (per FDA/EU standards), sensory evaluations (no odor/taste transfer), and dimensional accuracy checks (±0.1mm for critical sizes). Additional tests include pressure resistance (working pressure 1.5-6MPa, burst pressure 3x working pressure), thermal stability (-60℃ to 200℃), and abrasion resistance (≥50,000 cycles without core damage). All tests are documented for traceability.
Key Traits & Performance Advantages
Our food-grade braided silicone tubing stands out for its unbeatable combination of food safety, hygiene, durability, and versatility:
-
Global Food Safety Compliance: 100% food-safe, odorless, and tasteless—passes rigorous extraction tests (70℃, 24-hour soak in water, 3% acetic acid, 50% ethanol) with volatile substances ≤ 0.5%. Fully compliant with major international food contact standards for peace of mind.
-
Hygienic & Easy to Clean: Smooth inner surface prevents residue buildup and bacterial growth, compatible with CIP (Clean-in-Place) and SIP (Sterilize-in-Place) systems, including 121℃ high-temperature steam sterilization.
-
Reinforced Durability & Pressure Resistance: Braided layer protects against abrasion, kinking, and expansion under pressure, extending service life by 3-5x vs. non-braided food-grade silicone tubing. Ideal for high-pressure filling lines and peristaltic pump applications.
-
Broad Temperature Adaptability: Operates reliably from -60℃ to 200℃ (-76°F to 392°F), suitable for both cold-chain (refrigerated fluids) and hot-fill (pasteurization) processes in food production.
Industry-Specific Applications
Our food-grade braided silicone tubing is tailored for hygiene-critical fluid transfer in food, beverage, and pharmaceutical sectors:
-
Food & Beverage Processing: Transfer of milk, edible oil, fruit juice, syrup, beer, and wine. Ideal for filling lines, mixing equipment, and tank trucks—compatible with hot-fill (150℃) and cold-chain (-60℃) operations.
-
Dairy & Confectionery: Transport of raw milk, yogurt, cheese curd, and chocolate syrup. Smooth inner surface prevents bacterial growth, while heat resistance handles pasteurization (121℃) and sterilization.
-
Pharmaceutical & Nutraceutical: Transfer of medicinal liquids, herbal extracts, and dietary supplement bases. Complies with USP Class VI biocompatibility standards, ensuring safety for pharmaceutical use.
-
Commercial Kitchens & Catering: Use in dishwashers, steam ovens, and beverage dispensers—resists high temperatures and frequent cleaning, maintaining hygiene in busy kitchen environments.
-
Baby Food & Cosmetics: Precise filling lines for baby food, purees, and cosmetic bases (where food-grade safety is required). Odorless and tasteless properties prevent contamination of sensitive products.
