Food-grade rubber O-rings In short, food-grade rubber O-rings are O-rings produced from food-grade rubber raw materials, mainly referring to the performance of the environmental protection level. The materials generally use nitrile rubber, silica gel, ternary propylene rubber, natural rubber, neoprene rubber, fluorine rubber, etc. Generally speaking, there are many kinds of silica gel materials. Food grade silica gel is made of silicate inorganic polymer gel material. It shrinks and consists of silica. Its content exceeds 98%, it is non-toxic and tasteless, its chemical properties are stable, and it does not reflect any acid-base salts. Because it is a colloidal structure, it has a large number of micropores and a large specific surface. The porosity of edible silica gel is about 8 to 10 nanometers, the specific surface area is 300-500 square meters/g, and the surface water and water have strong water absorption, which can reach a weight of 8 to 10 under high humidity conditions. Therefore, food-grade silica gel can be used as a moisture-proof agent for food and external use. Food grade silicone is a special non-toxic commodity. It can be directly mixed with food, ensuring the drying of food and eating with food, without side effects on the human body. The key features of food-grade rubber O-rings are: 1. Non-toxic, no odor, high environmental protection level; 2. Soft, good elasticity, kink resistance and no deformation; 3. No cracking, strong and durable, cold and heat resistant; 4. It has high tear strength and superior electrical properties; 5. It will not yellow, frost, white, or fade when placed at room temperature, and it will not be scaled or odorless when placed in water for a long time. Food-grade rubber O-ring is suitable for Scope: 1. Equipment connection pipes, hoses, etc.; 2. Baby bottle straws, hoses, etc.; 3. Bread machine. Disinfection cabinet. Water dispenser. Kettle. Iron. Products, such as gas appliances, machinery, etc. . Electrical and other industries; 4. Connecting pipes for food machinery; 5. Water dispensers, coffee pots, connecting pipes for children's suction cups, hoses, etc.; 6. Construction. Road transportation. Sealed electronic instruments and parts.
