Self-healing plastic is a plastic in which damages are self-plugged by the release of special adhesive which is located in the plastic. The plastic can not only repair minor damage, but it can also close large holes.
The capillaries of the self-healing plastic are filled with chemicals. These are specially designed to recover. When the material breaks, these substances are released, and a gel is formed that restores the cracks and holes. The gel almost instantly hardens. Difficult replaceable parts could be made of this material, as well as bumpers of cars that recover immediately after an accident. According to the researchers, this is a breakthrough: It is now shown that you can repair lost material in plastic. By the use of Self-Healing Plastic, less material is wasted.
