UHMW PE is the strongest and toughest of all polyethylene grades for marine applications – even outlasting steel as a facing material, and many times better than timber facings. UHMW PE does not decay or rot, and is unaffected by marine borers. It is grain-free so will not splinter or crush, and can be cut, drilled and machined with ease. Most UHMW PE is supplied as Black – not just because this is the most economic choice, but also because black is manufactured using a double sintering process which work hardens the UHMW PE to further increase its abrasion resistance.
