Silicone ice cube trays are popular kitchen tools made from food - grade silicone, used for making ice cubes in various shapes and sizes. Here is an introduction:

Features

• Safety: Made of food - grade silicone, they are usually non - toxic, BPA - free, and meet international safety standards such as FDA, RoHS, or LFGB, ensuring they are safe for making ice cubes or freezing food liquids.

• Temperature Resistance: They can withstand a wide temperature range, typically from - 40°C to 230°C or even higher. This allows them to be used in the freezer to make ice and can also be used in the microwave or oven for other food - making purposes.

• Flexibility and Non - stickiness: Silicone is flexible, which makes it easy to release the ice cubes. You can simply bend or twist the tray to pop out the ice cubes without much effort. The non - stick surface also prevents ice cubes from sticking to the tray, ensuring easy demolding.

• Easy to Clean: The smooth surface of silicone ice cube trays does not easily accumulate dirt or odors. They can be easily washed by hand with warm soapy water or put in the dishwasher for cleaning.

• Reusability: They are durable and can be used repeatedly, which is environmentally friendly and cost - effective.
