❓ Frequently Asked Questions
Is this food-grade silicone tubing safe for direct food contact?
Yes. The 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 from -60℃ to 220℃, with short-term tolerance up to 250℃. This wide temperature range makes it suitable for both freezing and high-temperature sterilization applications in food processing and pharmaceutical industries.
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. All dimensions can be customized according to customer drawings or specific requirements. Please refer to the product specification sheet for standard tolerance values.
Is the silicone tubing compatible with CIP and SIP cleaning processes?
Yes. The tubing fully supports CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes. It can be cleaned using hot water, steam, or food-safe detergents, making it ideal for hygienic applications in food, beverage, and pharmaceutical production environments.
What hardness options 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 greater flexibility, while harder grades (60A–70A) provide higher tear strength (≧25–40 KN/m) and better structural rigidity. All grades maintain stable electrical insulation and temperature resistance.
What are the main application fields for this silicone tubing?
This tubing is widely used in food and beverage processing (milk, juice, beer, edible oil), pharmaceutical and biotechnology liquid transfer, laboratory reagent delivery, kitchen appliances (coffee machines, water dispensers, juicers), and food molding and decoration applications such as chocolate and candy molding.
