Abrasion of components which are subject to flow of materials across their surfaces is a perplexing matter for plant operators, as selection of the incorrect polymer material can have serious cost implications and associated down time on the processing plant.
Exceed Consulting can assist our clients by identifying the most appropriate polymer material to use for the application by testing materials on our rubber abrasion test apparatus, which has been design in accordance with ASTM 5963, DIN 53516 & ISO 4649.
The standard test involves running a polymer sample against a rotating drum coated with a carborundum sheet . The abrasion resistance is measured by moving the test piece across the surface of the abrasive sheet mounted to a revolving drum and is expressed as a volume loss in mm3 or abrasion resistance index percent. For volume loss, a smaller number indicates better abrasion resistance, while for the abrasion resistance index; a smaller number denotes poorer abrasion resistance.
Materials that can be tested in the abrasion test rig include:
