Safety and precautions for use of thermochromic pigments

Safety and precautions for use of thermochromic pigments:

All the color-changing pigments sold by the company do not contain toxic heavy metals such as mercury, lead, chromium, and are non-toxic and non-irritating to human skin. But because its particles are very small, after forming dust in the air, it is easy to enter the human lungs from the respiratory tract to deposit or enter the blood circulatory system, causing adverse consequences. Therefore, dust masks, rubber gloves and goggles should be worn during operation. If the color-changing pigment accidentally enters the eyes or mouth, rinse with plenty of water immediately to prevent it from entering the human body.

According to relevant national regulations, color-changing pigments are the same as ordinary pigments, and the part of their products containing pigments should avoid direct contact with food and drinking water. If it is used to produce temperature-changing plastic catering utensils, the double-layer injection molding process can be used, and the color-changing layer should be located in the part that does not contact with food.

The thermochromic pigment is non-flammable and will not ignite spontaneously when heated to 170°C in the air. However, due to its extremely fine particles and huge specific surface area, once dust is formed in the air and reaches a certain concentration, it may cause deflagration when exposed to an open flame. Please exercise caution.
