With the continuous improvement of people's living standards, the use of products and supporting product safety standards is also slowly improving, and silicone tube has become one of the essential supporting products in industry, food, medical, biopharmaceutical and so on. Children's milk bottle silicone tube, food and medical field connection tube, as well as industrial machinery and equipment transmission connection tube and industrial product protection sleeve; But how many people understand the testing standards and application standards of silicone tubes?
First of all: silicone tube commonly used environmental standards are divided into four grades: 1, RoHS; 2. FDA; 3. LFDB; 4. Biocompatibility report; The environmental standards of silicone products tested in these four detection reports are not the same, and the environmental protection levels are naturally different.
RoHS test (industrial grade silicone tube) : 6 items, namely lead (Pb), cadmium (Cd), mercury (Hg), hexvalent chromium (Cr6+), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs). From now on, it will be updated as 2011/65/EC, and the limit substances will be increased to 10, that is, di-n-butyl phthalate (DBP) will be added.
N-butyl benzyl phthalate (BBP), 2-hexyl phthalate (DEHP), hexabromocyclododecane (HBCDD). Industrial grade silicone tube is widely used in industrial machinery, equipment, electronics, toys, electrical appliances and other essential supporting products.
FDA testing (Silicone Tube for Food) US Food and Drug Standards Normal testing: Standard testing in accordance with Section 21CFR177.2600 of the US Food and Drug Administration Regulations. Food silicone tube is widely used in food, beverage, drinking water and other production process to play the role of conveying connection.
LFGB test (food grade silicone tube) German food and daily necessities standard normal test: Sensory test, total migration, volatile organic compounds, peroxide residues, organic tin, food-grade silicone tube is the most widely used in China than the milk bottle silicone tube, because newborns and too young infants resistance is relatively low, with LFGB standard food-grade silicone tube products is one of the most suitable products. LFGB food grade silicone tube standard is also one of the most requested standards for export customers in Europe and the United States.
Biocompatibility report (medical silicone tube) standard routine test five items: 1 cell, 2 sensitization, 3 skin irritation, 4 toxicity, 5 hemolysis. Medical silicone tube is widely used in medical machinery, medical instruments, medical instruments, biopharmaceutical and other essential supporting products for conveying connection.
