Synthetic
Synthetic consists of synthetically or semi-synthetically produced polymers. The first plastics were produced in the 19th century, consisting of natural substances such as rubber or cellulose. The production process was invented as early as 1531 by Wolfgang Seidel, who lived in Augsburg, Germany. Modern society would be unimaginable without plastics, as they are used in almost all areas of everyday life. They are malleable, hard, elastic and hard-wearing, they withstand a wide range of temperatures, offer thermal shape retention and resistance to chemicals. In terms of their physical properties, they are categorized in three groups: Thermoplastic, duroplast and elastomer.
