Notes:
1. Yield strength (Re): The stress at which a material begins to deform plastically.
2. Tensile strength (Rm): The maximum stress a material can withstand while being stretched or pulled.
3. Elongation (A): A measure of flexibility expressed as a percentage of the original length.
4. Impact energy (KV): A material absorbs energy during fracture at a specific temperature, indicating its toughness.

Remarks:
The values provided are typical for thicknesses up to 16 mm. For thicker materials, the properties might differ slightly.
As applicable, the impact energy values are specified for 0°C and -20°C.
