Definition of food silicone tube
Food grade silicone tubing is a type of conveyance hose specifically designed for applications in food processing, beverage production, pharmaceuticals, and medical fields.
Food grade silicone tubing is made from high-purity silicone rubber and is primarily used for transporting liquid, gaseous, or semi-solid food substances. Emphasizing safety, hygiene, and durability, it ensures no release of harmful substances or off-odors when in contact with food. Compared to standard industrial silicone tubing, its materials undergo rigorous purification and testing, making it suitable for high-temperature sterilization, cleaning, and long-term use scenarios.
