Safe and Non-toxic: An In-depth Look at Sanitary Silicone Hose and Its Applications

— Why More Customers Are Choosing DIAO Silicone Hose

In industries such as food processing, drinking water systems, and biomedicine, where safety and cleanliness are of utmost importance, even a small fluid transfer tube plays a critical role in quality control. Sanitary-grade silicone tubing has become an essential material in these fields due to its non-toxic, odorless, high-transparency, and temperature-resistant properties.

What Is Sanitary Silicone Hose?

Also known as food-grade or medical-grade silicone tubing, sanitary silicone tubing is made from high-purity silicone that meets FDA and LFGB safety standards. No plasticizers or harmful additives are used in its formulation, ensuring the tubing is non-toxic, tasteless, and completely safe for direct contact with food and liquids.

Key Features of Sanitary Silicone Hose

1. Non-toxic and Odorless for Maximum Safety

The tubing is made from high-transparency precipitated silicone and does not contain any artificial fragrance, softeners, or chemical additives. As a result, it is entirely tasteless, odorless, and chemically stable, making it safe for direct contact with food, beverages, and pharmaceuticals.

2. Outstanding Temperature Resistance

Sanitary silicone hose remains flexible and stable within a wide working temperature range of -60°C to +200°C, making it ideal for environments where hot and cold fluids alternate frequently, such as pasteurization equipment or hot beverage dispensers. It resists deformation and aging even under steam sterilization or boiling water cleaning.

3. Soft and Flexible

The tubing is highly elastic, allowing it to bend and flex in confined spaces without kinking or cracking. It maintains its shape and resilience after repeated compression and bending, ensuring a long service life and reduced downtime.

4. High Transparency for Visual Monitoring

With its high clarity, the tubing allows visual inspection of fluid flow, color, bubbles, and blockages, which is especially useful in food filling lines, laboratory systems, and precision fluid control equipment.

5. Not Resistant to Oil

It is important to note that silicone is not oil-resistant. This hose is not suitable for transferring oily substances such as vegetable oil, mineral oil, or lipid-based liquids. Oils can penetrate the silicone material, causing swelling, softening, or rupture. Sanitary silicone tubing is best suited for water-based fluids like pure water, juice, milk, alcohol, and pharmaceuticals.
