Application
UHMWPE has excellent abrasion resistance it is often used for lining chutes, hoppers,slideways and wear blocks in aggressive enironments. it is often found in food production environments where high volumes of containers need to be guided along conveyors or production lines. Because its low moisture absorption, it is also found in some high demand areas of marine applications. UHMWPE is sometimes used in cryogenic components due to its low operating temperature abilities.
Customers can make all kinds of special-shaped parts according to the drawing.
Any small size need us to cut , we can satisfy your special need .
Thanks for coming,looking forward to our cooperation.
