Frequently Asked Questions (FAQ)
Is this food-grade silicone tubing safe for direct food contact?
Yes. The 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 and phthalates, and certified by SGS, making it fully safe for direct food and beverage contact.
What is the operating temperature range of this silicone tubing?
The tubing operates stably from -60℃ to 220℃, with short-term tolerance up to 250℃. It also withstands a use temperature range of -50℃ to +200℃ under standard operating conditions, making it suitable for both hot and cold process applications.
Can the inner diameter and wall thickness be customized?
Yes. The tubing is available in 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 and specific requirements.
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-grade detergents. Avoid using strong oxidizing agents or harsh solvents without prior compatibility testing.
What industries is this silicone tubing most 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, water dispensers), and food molding & decoration applications.
What hardness grades are available, and how do they affect performance?
The tubing is available in Shore A hardness grades of 40A, 50A, 60A, and 70A. Softer grades (40A–50A) offer higher elongation (≧500%) and flexibility, while harder grades (60A–70A) provide increased tear strength (up to ≧40 KN/m) for more demanding applications.
