4.3.2 EPDM (ethylene propylene diene monomer rubber) is a type of synthetic rubber, is
elastomer. The main properties of EPDM are excellent heat, ozone and weather resistance. It is
widely used as a thermal and water insulator.

Anodizing is an electrochemical process of obtaining a protective or decorative coating on the
surface of various alloys. Aluminium alloys are anodized to increase corrosion resistance, to
increase surface hardness, and to allow dyeing (coloring), improved lubrication, or improved
adhesion. The anodic layer is non-conductive.

Painting (polyamide powder painting) is powdered composition based on polymer, curing agent,
pigment, llers and some other special components. It is applied for a painting of aluminum
proles. The thickness of the layer is several microns.

Wood Effect is the process of applying a wood grain effect onto aluminium. Currently, it is
considered the best product on the market for wood decoration.
