Polystyrene is a polymer from the styrenics family that offers excellent transparency coupled with a very competitive cost. It has medium mechanical properties making PS rigid and brittle.

Polyvinyl chloride or PVC is a plastic material obtained by polymerization of vinyl chloride monomer. It is an amorphous polymer with very low crystallinity.

The moulding of this polyurethane provides excellent damping at room temperature.

The moulding of this polyurethane offers a very good transparency (quasi-optical quality), an excellent resistance to Uvs, and the absence of yellowing.

The moulding of this polyurethane offers very good static and dynamic properties.
