If you want a wheel that is strong and non-skid, these
skidproof polyurethane wheels are ideal. As the name implies, these are constructed
from polyurethane, a kind of plastic that is incredibly robust and
skid-resistant. They offer the advantages of rubber wheels while having a far
higher load capability than rubber wheels (such as noise reduction, shock
absorption, and floor protection). Skidproof polyurethane wheels offer far
higher levels of resilience to wear and abrasion than rubber casters, which
tend to lose tread pieces over time as they are utilised. These are used in
wheelchairs, stretchers, trolleys etc. for smooth movement from one spot to
another. A polyolefin centre is joined mechanically and chemically which outperform
rubber in resisting grease, oil, cutting, chunking, and abrasive wear.
