Frequently Asked Questions
Is this silicone tubing truly food-safe and certified?
Yes. Our food-grade silicone tubing complies with U.S. FDA 21 CFR 177.2600, EU EC 1935/2004, and China GB 4806.11 food safety standards. It is free from BPA, phthalates, and other harmful substances, and has been certified by SGS and other authoritative testing bodies.
What temperature range can this silicone tubing withstand?
The tubing operates stably from -60℃ to 220℃, with short-term resistance up to 250℃. This makes it suitable for both freezing applications and high-temperature sterilization processes such as steam autoclaving.
Can the inner diameter and wall thickness be customized?
Yes. We offer a wide range of inner diameters from Φ0.4mm up to Φ75mm, with various wall thickness options. Custom sizes are available according to customer drawings or specific requirements. Please contact us for a tailored quote.
How should this silicone tubing be cleaned and sterilized?
The tubing supports both CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes. It can be cleaned using hot water, steam, or food-safe detergents. Always ensure cleaning agents are compatible with silicone before use.
What industries and applications is this tubing suitable for?
This tubing is widely used in food & beverage processing (milk, juice, beer, edible oil), pharmaceutical & biotechnology (liquid transfer, bioreactor connections), kitchen appliances (coffee machines, juicers, water dispensers), and food molding & decoration (chocolate, candy, cake).
Are there any precautions when using this tubing with chemicals?
While the tubing is resistant to weak acids, alkalis, and oils, we strongly recommend conducting a compatibility test before use with strong acids, strong alkalis, or organic solvents. This ensures the material maintains its integrity and safety in your specific application environment.
