Both food grade silicone hoses and medical silicone hoses require relevant medical food testing certificates. Since both of them can be in direct contact with the human body, they are very strict on production safety. Therefore, it is equally difficult to ask: the same is strict for health and safety. Where are the essential differences between them?
The first is the conceptual difference:
Food grade silicone hose: Imported silicone raw material, using scientific production technology, using batch method to produce glue, high tear resistance and high transparency for gas phase glue, super high and low hardness of compound rubber, functional mixing Silicone hose with characteristics such as glue, this product has a wide range of adaptability. Compared with the traditional double-four-four-vulcanization process, the silicone hose and the silicone profile have the advantages of high transparency, odorlessness, no yellowing, no blooming, and the like, especially solving the problem of black rubber hose blooming and blue product fading.
Medical silicone hose: imported silicone rubber material, the smallest inner diameter can be 0.4 mm, through the biocompatibility test, the reaction to human tissue is very small, the value will not cause foreign body reaction after entering the human tissue, the surrounding tissue No inflammation occurs, and the hose can be placed in the human body for 20 days without abnormal reaction. The life of the silicone hose for the peristaltic pump can be continuously used for more than 175 hours. Therefore, it has become more and more widely used in medical and health care.
Second, compare the differences between their characteristics.
Food grade silicone hose features:
1) Food grade silicone is a kind of environmentally friendly silicone with non-toxic odor and high transparency;
2) Soft, good elasticity, no kink resistance;
3) No cracking, long service life, cold resistance and high temperature resistance;
4) Has higher tear strength and superior electrical performance;
5) Keep the yellow at room temperature, do not spray frost, do not spit white, do not fade, leave no water in the water for a long time, no odor.
Characteristics of medical silicone hose:
1) Medical silicone hose, cold and high temperature resistant, resistant to weak acid and alkali, harmless, non-toxic and tasteless;
2) High transparency, high elasticity, and strong UV resistance;
3) Knuckle resistance, no deformation, softness, arc resistance, corona resistance, chemical stability, physiological inertness, non-toxic, non-irritating, hydrophobic, breathable, excellent resilience, permanent deformation, etc. 50 ° C to 250 ° C use, special requirements for accessibility, excellent insulation, can be sterilized with ethylene oxide under high temperature conditions.
4) In line with the food and drug testing standards, the room temperature is not yellow, no frosting, no whitening, no fading, and no water in the water for a long time.
In summary, most of the characteristics of food grade silicone tubing and medical silicone tubing are the same. The above is the similarities and differences between them, I hope to help everyone.
