Plastic hoses are used as flexible connections in various industrial machines. They are primarily used to transport fluids, granulates and powders, but also to protect the conveyed medium from environmental influences. In contrast to rubber hoses, plastic hoses can be manufactured in any color or even transparent. This guarantees a clear view of the conveyed medium. In addition to the material-specific properties of plastic, (textile) inserts as well as plastic spirals or metal spirals can be incorporated into the hoses. Plastic hoses are used, for example, in mechanical engineering, the construction industry or in wind energy, but are also found in the chemical industry and in agricultural engineering.
