1. Basic properties of silicone materials
(I) Temperature resistance
Silicone is a material with excellent temperature resistance that can maintain the stability of its physical and chemical properties over a wide temperature range. Generally speaking, the temperature resistance range of food-grade silicone is between -40℃ and 230℃. This means that silicone can remain flexible at extremely low temperatures without becoming brittle or cracking, and can also be used in high temperature environments without deformation or release of harmful substances.
(II) Chemical stability
Silicone has good chemical stability and is not easy to react chemically with other substances. This prevents silicone products from releasing harmful chemicals when they come into contact with food and beverages, ensuring food safety. Food-grade silicone has undergone rigorous quality testing and complies with relevant food safety standards, such as the US FDA standard or the European LFGB standard, to ensure its safety under normal use conditions.
(III) Flexibility and elasticity
Silicone has excellent flexibility and elasticity, and can deform when subjected to external force, and can return to its original shape after the external force disappears. This property makes the silicone kettle more convenient during use. For example, it can be easily folded, curled or squeezed, which is convenient for carrying and storage. At the same time, the flexibility of silicone also makes it difficult to break when impacted, and has good fall resistance.
2. The feasibility of silicone kettles for hot water
(I) High temperature resistance
Based on the temperature resistance of silicone, silicone kettles can be filled with hot water. Under normal use conditions, silicone kettles can withstand the temperature of hot water without deformation or damage.
