Wicthan® (85–95 Shore A)
Wicthan® (85–95 Shore A)
Wicthan®: General-purpose industrial polyurethane with many hardness options. Low rolling resistance, good abrasion resistance and grip, hydrolysis resistant for damp environments; cost-effective in volume.
Typical Operating Conditions
- Typical equipment: forklift, heavy-duty AGV and robot drive wheels; assembly line equipment.
- Load and speed: medium loads, frequent acceleration and braking, multi-shift duty.
- Environment: indoor and outdoor floors; hydrolysis resistant, suited to wet floors.
