一.What is a transparent silicone tube
A transparent silicone tube is a flexible tube made of silicone that is clear and lets you see the liquid flowing through it. Some of its primary features are:
High and low temperature resistance: It can usually handle temperatures between -40 and 200 degrees Celsius for a long time, and it can handle temperatures between 230 and 250 degrees Celsius for a short time
It's important to remember that transparency is just a visual trait and can't tell you if the silicone tube is safe for food. Both the food and industrial industries use clear silicone tubing. Industrial tubing may have additives that move around, but food contact silicone tubing must meet strict material and testing criteria.
二. Transparency does not equal food grade: common misconception
Transparency is safe: Transparency is only a colour and doesn't show that the pipe is safe to eat or doesn't contain harmful substances. Many clear silicone hoses used in factories are utilised in machines or chemicals and may have additives that are not safe for food.
High temperature resistance is food grade: Temperature resistance just means that the pipe can handle a specific temperature; it does not mean that it meets FDA, LFGB, or EU food contact rules.
Food grade clear silicone tubes normally contain high-purity raw materials and go through thorough testing, which makes them more expensive than regular industrial pipes. Cheap pipes might only be good for things that don't involve food.
三. Determine the standard for transparent food grade silicone tubing
Certification from an authorityClear food-grade silicone tubing must have official certification, which includes:FDA stands for Food and Drug Administration.LFGB (German Standard for Food Contact Materials)EU 1935/2004 (EU Food Contact Regulation)Suppliers should have to give PDF format testing reports and check that testing companies like SGS, T Ü V, Intertek, BV, and others are legitimate when they buy something.
Materials used Platinum Cured Silicone is what most food contact silicone tubing is made of.Doesn't smell or hurt youStable performance at high and low temperaturesCan be used in coffee machines, drinks, dairy products, and other places.You can vulcanise regular clear silicone tubing using peroxide, however it is not safe to touch food with it.No smellFood-grade silicone tubing that is clear must not have any smell and must not smell even after being rinsed with hot water. Any smell of rubber could make food taste bad or make it taste bad.
四. Testing for migration
Silicone tubes that touch food must be tested for migration to make sure that dangerous contaminants don't get into the food.Test for total migration volumeTest for migration of a certain materialTest for oil at high temperaturesThe LFGB testing standards are very high, which makes them perfect for shipping to Europe.
五. Smoothness of the inner wall
The inside wall of high-quality, clear, food-grade silicone tubing should be smooth, easy to clean, not prone to scaling, and not prone to mould formation. The smoothness of the inner wall has a direct effect on the effectiveness of high sanitary standards for things like beer, dairy goods, and drinks.
六. Clearly state the purpose
Regular providers will explicitly label what clear silicone tubing is for, like:Silicone Hose for FoodApproved for Food ContactCompliewiFDAandLFGBDescriptions that are not clear, such "universal silicone tubing," frequently do not meet food contact safety standards.
