Plastics differ from polymers due to the addition of additives. Typical additives include plasticisers, stabilisers, colourants, fillers and reinforcing agents. Plastics can be classified according to various criteria, e.g. molecular synthesis, molecular structure, chemical origin or, based on their mechanical and thermal behaviour, into the three main groups: thermoplastics, thermosets and elastomers.

Chrome plating is carried out in accordance with DIN EN ISO 1456 Metals such as steel, stainless steel, aluminum, bronze, iron, brass, copper and die-cast zinc can be chrome-plated. The chrome surface is applied to a thick nickel undercoat. This is a durable and robust application that is less susceptible to wear and scratches.
