Frequently Asked Questions
QIs this food-grade silicone tube safe for direct contact with food and beverages?
Yes. Our food-grade silicone tubes fully comply with U.S. FDA 21 CFR 177.2600, EU EC 1935/2004, and China GB 4806.11 standards. They are free from BPA, phthalates, and other harmful substances, making them completely safe for direct food and beverage contact.
QWhat is the operating temperature range of the silicone tube?
The silicone tube operates stably from -60℃ to 220℃, with short-term usage up to 250℃. This wide temperature range makes it suitable for both freezing and high-heat sterilization applications.
QCan the inner diameter and wall thickness be customized?
Yes. We offer a wide range of inner diameters from Φ0.4mm to Φ75mm, with various wall thickness options. Custom sizes can be produced according to customer drawings or specific requirements. Please contact us for custom orders.
QHow should I clean and sterilize the silicone tube?
The silicone tube supports both CIP (Clean-in-Place) and SIP (Sterilize-in-Place) procedures. It can be cleaned using hot water, steam, or food-safe detergents. Avoid using strong oxidizing acids or chlorinated solvents without prior compatibility testing.
QWhat applications are these silicone tubes suitable for?
These tubes are widely used in food & beverage processing (milk, juice, beer, edible oil), pharmaceutical & biotechnology (liquid transfer, bioreactors), kitchen appliances (coffee machines, water dispensers, juicers), and food molding & decoration.
QWhat hardness grades are available, and how do I choose the right one?
We offer four hardness grades: 40A, 50A, 60A, and 70A (Shore A). Softer grades (40A–50A) provide greater flexibility and higher elongation, ideal for applications requiring frequent bending. Harder grades (60A–70A) offer higher tear strength and are suitable for high-pressure or structural applications. Our team can recommend the best grade based on your specific use case.
