Polyurethane Liner

Polyurethane liners are a synthesis of polyols & isocyanides chain extended or cross linked into giant molecular complexes. This 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 behind the liner plate hence preventing bulging of the liner which otherwise causes liner dislodging. They are harder material compared to rubber but softer than plastic and provide an excellent degree of abrasion resistance together with flow ability.
