Frequently Asked Questions
-
Is this food-grade silicone tubing safe for direct food contact?
Yes. Our platinum-cured silicone tubing fully 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, making it completely safe for direct food and beverage contact. -
What is the operating temperature range of this silicone tubing?
The tubing operates stably across a wide temperature range from -60℃ to 220℃, with short-term peak tolerance up to 250℃. This makes it suitable for both freezing and high-temperature sterilization applications in food processing and pharmaceutical industries. -
Can the silicone tubing be customized in size and color?
Yes. We offer a wide range of inner diameters from small to large bore, all customizable according to your drawings or specifications. The standard color is high transparency, and custom colors are available upon request. Please contact us with your requirements for a tailored solution. -
How should I clean and sterilize the silicone tubing?
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. Avoid using strong oxidizing agents or solvents unless compatibility testing has been performed beforehand. -
What industries and applications is this silicone tubing suitable for?
Our food-grade silicone tubing is widely used in food and beverage processing (milk, juice, beer, edible oil), pharmaceutical and biotechnology (liquid transfer, bioreactors), kitchen appliances (coffee machines, juicers, water dispensers), and food molding and decoration (chocolate and candy molding, cake decorating). -
What hardness options are available and how do they affect performance?
We offer four Shore A hardness options: 40A, 50A, 60A, and 70A. Softer grades (40A–50A) provide greater flexibility and higher elongation (up to 500%), while harder grades (60A–70A) offer increased tear strength (up to ≧40 KN/m) and better dimensional stability. The choice depends on your specific application requirements such as pressure, flexibility, and connection type.
