Product Features:
Resistant to high and low temperatures, the use temperature range is -50℃ to +250℃. It can be used in refrigerators, microwaves, and electric ovens. Due to the excellent elasticity of silicone, it naturally forms an internal negative pressure state when covering the container, completely isolating the circulation of internal and external gases, and the sealing performance is unparalleled. When used to cover bowls, pots, basins, and other items in the refrigerator, there will be no cross-contamination. Due to the complete isolation of air from entering, the best fresh-keeping effect can be achieved.
The thermal conductivity is only 0.27, which is about 1/1000 of that of metal, making it ideal for covering bowls, pots, and basins, resulting in excellent insulation effects.
Silicone, composed of silicon-oxygen bonds, is ultra-durable against aging, with a normal service life of over 30 years.
Based on the sizes of common household containers, a variety of size freshness covers are provided for selection.
