Polyurethane elastomers are a synthesis of polyoles & isocyanides chain extended or cross linked into gaint molecular complexes. The material has combined properties of rubber as well as plastic.

Polyurethane wear plates are normally steel backed plates where steel is bonded with polyurethane available in customized sizes. The backing steel prevents fines to penetrate beneath & hence bulging of the liner which may cause its dislodging. They are harder materials compared to Rubber but softer than plastics and provided on excellent degree of abrasion resistance.

Apart from Steel Backing Polyurethane Liner, PU-PM wear plates comprises of Special Steel Inserted ribs bonded within Polyurethane , which enhances the impact resistance of Polyurethane.
