We often get asked why QuayQuip only uses virgin grade UHMW-PE when other companies propose regenerated and double sintered grades. So we asked external experts to look at the properties and performance of both virgin and recycled grades. The results confirmed why virgin UHMW-PE is the only grade that QuayQuip recommends as safe for marine fenders.
Material grades There are two classes of UHMW-PE for fenders – first quality virgin grade and ‘everything else’. First quality virgin grade UHMW-PE contains no scrap materials, bulk fillers or anything that detracts from ultimate performance.
‘Everything else’ includes: – Recycled, regenerated and double sintered UHMW-PE (different names for the same thing) – Blended UHMW-PE which, as the name implies, is ‘cut’ with scrap and low-grade polyethylene to cut costs at the expense of performance and life expectancy.LinkedInFacebookTwitterGoogle +1EmailMoreStumbleUponDiggTumblrRedditPocket
