Blicthan® (95±2 Shore A)
Blicthan® (95±2 Shore A)
Blicthan®: High-purity refined polyurethane with very high abrasion resistance. Stable, consistent properties from batch to batch; long service life under heavy load at low speed, suited to dusty or abrasive duty.
Typical Operating Conditions
- Typical equipment: screening machine drive wheels, idler rollers and support rollers, bulk handling, heavy machinery.
- Load and speed: very high loads at low speed (≤16 km/h); continuous heavy-duty running.
- Environment: abrasive, dusty or gritty conditions; where wheel replacement is costly.
