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.

Table 4.3.2 EPDM typical properties

Hardness 80±5 oSh
Tensile strength 10 N/mm2
Breaking strain 150% (minimum)
Compression (22h/70 oC) 25% (maximum)

4.3.3 Polystyrene is a polymer which has good thermal insulation and frost-resistance
properties. It is often used as building insulation materials.

Table 4.3.3 Typical properties:

Density 105 kg/m3
Thermal conductivity 0.08 W/(m·K)
Tensile strength 46–60 MPa
Coefficient of thermal expansion 8×10−5 / oC

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.
