Not normal at all, properly manufactured UHMWPE line should be quite stiff and smooth even after working due to its individual fibre coatings for UV protection and chafe resistance. Dyneema and ISM are the two original manufacturers and license
to others (such as Hampidjan). Acera (Timm Ropes) is a big one in Northern Europe
(comes in yellow) that is properly formulated. Cheap
UHMWPE line (aka Chineema, but of course is made elsewhere too) may be externally coated only, so the individual fibres will fluff and fray as they are exposed due to splicing. OK for non critical work
, but nothing where you expect consistent strengths.
