Surface

The surface of a plastic part forms the outer interface of this body, which is crucial for its functionality and aesthetics. It can be specifically modified to meet the particular requirements of various applications. A wide range of properties shapes the nature of the surface, including roughness, surface resistance to various influences, polarity, which affects the adhesion of coatings, hardness, scratch resistance and sliding properties.

In surface technology, the term "surface" refers to a thinly applied layer that is applied to the substrate. This layer can fulfil a wide variety of functions, from improving the mechanical properties to modifying the visual appearance.
