1.8 Surface finish and cleanability
In moulding technopolymers, it is technically easier to make products with a rough matte surface finish, which hides any aesthetic defect such as shrinkage cavities, flow marks, or joining marks caused by non-optimum moulding processes. However, a rough matte finish makes it more difficult to clean the component, especially if made out in light colours, and its handling for a long use.
ELESA technopolymer Standards have a very fine matte finish so that the product remains easy to clean in time, and it is easier for the user to handle it. Some groups of technopolymer products have recently been developed with a completely glossy finish, so that they remain clean for a long time.
