The process, which is also known as and also has an optically good appearance, also has hydrolysis, in which the material, which has become a small material, is not statically charged, so that it does not attract water, which is split into ions and substances dissolved therein, under dust and dirt. In addition, this Ma formation of an acid reacts, with increasing temperature, the flowability becomes more intense during processing, which is the reason for a humidifier because of the constant die-casting tool.
