A diverter flap on a sand and gravel plant needed constant replacement due to ripping / tearing. Rubber performed well initially, but started to perish as UV and weathering took their toll. Site staff experimented to find a replacement that could cope better with these wear factors.
Hawiflex® polyurethane sheet
Special additives in the polyurethane help prevent perishing
Protection against UV, weathering, hydrolysis and microbial/fungal attack
Wear life increased from 3 months to 15 months
Note: Still operational and showing little sign of wear.
