Grade silica gel is a general term for a relatively large category. It is environmentally friendly, non-toxic and tasteless, and will not emit any toxic and harmful substances during the production process.
How long can food-grade silica gel last? According to the type of silica gel material selected, such as LSR injection molding silica gel, it is usually used to make maternal and child products, silica gel products, etc. According to the performance grade material selected, the aging resistance is usually three to five years. It is not a big problem, and products made of materials with better performance will have a longer service life, which can reach 10 years or more.
Another type of food-grade silica gel is liquid and fluid silica gel. Like LSR injection glue, it is AB two-component silica gel, but the difference is that LSR injection glue has a high viscosity and must be heated by machine injection. And this can be operated manually and by machine, and can be cured quickly by room temperature vulcanization or heating. The service life of finished products can also reach three to five years. The performance of silicone increases with time, storage adjustment and frequency of use, and the performance is gradually aging.
