Silicone is divided into food grade silicone and industrial grade silicone, so what is the difference between them? How do we choose when we buy?


First, food grade silicone


Food grade medical silica gel uses imported pure silicone rubber raw materials with stable chemical properties, good reagent resistance, resistance to weak acid and alkali, chemical reagents, liquid medicine, alcohol, etc. Some imported materials have passed biocompatibility cytotoxicity test, in line with ISO10993 USP Class VI standard.


Food-grade silicone is mainly used for medical equipment accessories, medical catheters, using antibacterial design to ensure the use of safety, food-grade silicone tubes are usually used for drinking fountains, coffee machine diversion pipes, and household appliances waterproof line protection, for medical equipment connection pipes, catheters, etc. Baby bottle straws, catheters, etc.; Electrical instruments and other casing, profile; Tube products for food; Connecting pipe for food machinery; Water dispenser, coffee pot, children suction cup connecting pipe, catheter, etc.
