What are PU wear parts?
PU wear parts are hard ceramic wear-protection components made from alumina or silicon-carbide ceramic combined with rubber, polyurethane or epoxy, used to protect equipment from abrasive and impact wear. A ceramic wear face is bonded to rubber, polyurethane or epoxy, marrying hardness with impact absorption. In mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants, they extend equipment life and cut maintenance.
What are PU wear parts used for?
They line chutes, hoppers, bunkers, mills, pulleys and conveyor transfer points where bulk solids or slurry scour metal away. Typical users are mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
What material and properties make PU wear parts effective?
A ceramic wear face is bonded to rubber, polyurethane or epoxy, marrying hardness with impact absorption. These properties let PU wear parts outlast steel and rubber in abrasive service.
Why choose PU wear parts over steel or rubber alternatives?
PU wear parts beat plain metal, rubber or polymer on abrasive duties: steel erodes in months and can contaminate product, while rubber gouges under lump impact. PU wear parts hold dimension, cut downtime and typically last 5–10× longer in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
How do I select and specify PU wear parts?
Pick tile grade (92%/95%/99% alumina, ZTA or SiC) and backing (steel-stud, rubber-embedded or adhesive) to your wear mode, then send equipment drawings so FIRSTAR supplies matched tiles or panels.
Can PU wear parts be installed on curved surfaces?
Yes. Mosaic and hex ceramic mats conform to curved chutes, pipes and cones, while flat tiles suit hoppers and bins. FIRSTAR provides the right shape and backing for your profile.
