Fender Systems UHMW-PE UHMW-PE Trelleborg ultra high molecular weight polyethylene (UHMW-PE) is the first choice material for facing steel fender panels and other heavy duty applications. It combines very low friction with excellent impact strength and a wear resistance much better than steel. The standard colour is black, but if other colours are needed then ‘virgin’ grade also comes in yellow, white, grey, blue, green and red. UHMW-PE materials are compounded to resist ozone and UV radiation. They do not degrade or rot and are easily recycled at the end of their useful service life. Features Very low friction coefficient Excellent abrasion resistance UV and ozone resistant Does not rot, split or crack 100% recyclable Applications Fender panel (frame) face pads Rubbing strips V-fender shields Lock entrance and wall protection Bridge buttress protection Beltings on workboats Holland USA Refer to Section 12 (Fender Design) for guidance on using UHMW-PE as a fender facing. 39
