S2 is a wood material, in which polypropylene acts as the bonding agent and which thus combines the properties of thermoplastic materials with those of classical wood materials. Many shapes are possible. Werzalit S2 is highly resistant to bending or flexible, watertight, pliable in a hot state and at the same time can be processed like wood. S2 can be moulded when heated and functional parts can thus be integrated and even embossings applied. S2 is weather and UV resistant, watertight, and halogen-, chlorine- and formaldehyde-free.
