Extended data:
The difference between food grade silica gel and medical silica gel;
1, performance
Food-grade silica gel: the nozzle is round, not flat, with small stress, less materials used in two counties and uniform wall thickness. The product has stable chemical properties and good reagent resistance. Some imported materials have passed the biocompatibility cytotoxicity test, and meet the sixth class standard of ISO 10993 USP.
Medical silica gel: highly transparent, environmentally friendly and tasteless, after high temperature disinfection and high pressure sterilization. High and low temperature resistance, high temperature deformation, no harmful substances, aging resistance. Passed the biocompatibility test.
2. Application area
Food-grade silica gel: Food-grade silica gel tubes are mainly used as medical device accessories and medical catheters, designed with inhibition function to ensure safety. Food-grade silicone hose is usually used as the diversion pipe of drinking machine and coffee machine, as well as the ventilation pipe maintenance of household appliances and the connecting pipe and conduit of medical equipment. Bottle mouth, conduit, etc. Baby bottle; Electrical and instrument housings.
Medical silica gel: Medical silica gel tubes are widely used in oxygen respirators, medical catheters, pharmaceutical equipment, infusion catheters, cosmetics, biological research, chemical experiments, food and beverage delivery, and veterinarians.
