In high-temperature cooking scenarios such as rice cookers, the temperature resistance of gas-phase silicone is particularly critical. It can maintain stable physical properties over a wide temperature range (usually up to -40 ° C to 200 ° C or above), and will not cause the sealing ring to harden, crack or soften deformation, whether it is continuous high-temperature steam during cooking or storage in low-temperature environments in winter.

At the same time, gas-phase silicone has an extremely low compression permanent deformation rate, which means that even under the pressure of the rice cooker lid being closed for a long time, the sealing ring can quickly restore its original shape after opening, providing reliable sealing pressure and ensuring stable pressure during cooking, locking in the aroma and moisture of rice.

In addition to excellent mechanical and thermal properties, the safety and environmental protection characteristics of gas-phase silicone also fully meet the high standard requirements of food contact materials. It is non-toxic and odorless, with extremely stable chemical properties. It does not react with water, weak acids or bases under normal conditions, and does not release harmful substances during high-temperature heating. Its surface is smooth and dense, not prone to bacterial growth, easy to clean, and provides a solid guarantee for healthy eating.

In addition, gas-phase silicone also has excellent aging resistance, ozone resistance, and electrical insulation properties, further extending the overall service life of electrical products.
