termorettejä

Termorettejä, also known as thermorettes, are small, disposable heating pads designed for personal use. They contain a mixture of iron powder, activated carbon, salt, and water. When exposed to air, the iron powder undergoes an exothermic oxidation reaction, generating heat. This process is initiated by the opening of the packaging, which allows oxygen to enter and react with the iron. The salt acts as a catalyst, speeding up the oxidation, while the water is necessary for the reaction to occur. Activated carbon helps to distribute the heat evenly and maintain the temperature.

Termorettejä are commonly used to provide warmth in cold weather, offering a convenient way to warm hands, feet, or other body parts. They are typically small and flexible, allowing them to be placed inside gloves, shoes, or pockets. The heating process is gradual and can last for several hours, providing sustained warmth. Once the reaction is complete and the pad has cooled, it is disposed of as regular waste. They are a popular item for outdoor activities, sporting events, or simply for staying comfortable during cold seasons. The specific composition and duration of heat can vary slightly between different brands and types of termorettejä.
