UHMWPE Liner
UHMWPE (Ultra High Molecular Weight Polyethylene) is lining material that is used to reduce flow problems of bulk solids in bins, hoppers, chutes, truck beds and bulk material handling for the Mining Industry.
Benefits include:
Very High Impact Strength
Exceptionally low friction
Low water absorption
Chemical Resistant
Wear and abrasion resistant
UV Stability
High Operating Temperature
Economic Advantages
Lower Cost for lining an existing bin is about one third of the cost of construction steel.
Lower Weight: only 1/7 of steel sheet, makes installation simpler.
Longer Life Span: In the sand slurry test UHMWPE is significantly longer than conventional steel.
Size: 1000 mm x 1000 mm, 1000 mm x 2000 mm
Thickness: 3 mm - 100 mm
