The conveyor in question was running well over 5m\/s.<br><br>When standard polyurethane (PU) impact rollers were trialled on this particular impact table (where temperatures at the bearing were reaching over 600C [1400F]*), the PU shells were melting onto the centre idler frames within 24 hours.<br><br>This is because the force from the impact on the outer surface of the roller will cause the shell material to heat. This heat generation increases with load and speed, and is seen to some degree across all shell materials.<br><br>As the impact forces on this impact table and other similar applications are constant and repeated that warming quickly escalates, and in this case was enough to melt traditional PU. CPS experts developed a new PU formulation (PU Plus) to solve this issue.<\/p>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<p>After visiting site in 2022 to inspect and audit the impact table our mechanical and chemical engineering team spent many months of exhaustive testing to create a new polyurethane formulation to suit such an application.
