Polyurethane screens can be provided with tabs for tensioning, or in a variety of common modular hooking systems. The polymer that constitutes them exhibits good abrasion resistance, and can be provided with a hardness between 65º e 95º Shore “A”. Sloted Polyurethane screens have flat top surface, the assembly is by frames and are recommended for screening of small sized products.

Usage

These screens for sieves are advised for sand washing and to use as drainers
