Clay is something that people use to make things out of. It's kind of like play dough, but it's a little bit different. Some types of clay are very soft and gooey, while others are harder and more solid.
Industrial plasticine, which is also called modeling clay or plastic clay, is a type of clay that is used by scientists and engineers to make models of things they want to build. It's really important to make sure that the model they make is really precise, because it helps them figure out how to make the real thing.
The reason why industrial plasticine is so great for this kind of work is because it is very easy to shape and mold. If you want to make a model of a car, for example, you can use the clay to make a little version of the car that looks exactly like the real thing.
Industrial plasticine is also really helpful because it doesn't dry out like some other types of clay. That means that the scientists and engineers can work on their models for as long as they need to without worrying about the clay getting hard and ruining everything.
So, to sum it up, clay is something that people use to make things out of. Industrial plasticine is a special type of clay that scientists and engineers use to make precise models of things they want to build. It's easy to shape and mold, and it doesn't dry out like other types of clay.
