WebPolymers Materials are chosen based on factors including working properties, aesthetics, environmental impact, function, manufacturing processes etc. It is important to choose a material fit for purpose. WebSurface finishes. Some polymers that are formed in a mould are self-finishing, meaning that the inside surface of the mould is so smooth that the form that is taken from it is also smooth. A motorbike helmet is a good example - the outside of the helmet is smooth because of the mould it was made in. Once a polymer has been cut or shaped from ... orc 719.01
