Development of roughness and decrease in hardness of abrasive wear surface in various types of polyethylene. Part II.

Abstract

Samples of eight grades of polyethylene from various manufacturers: PE100 2NT11-9 (Kazanorgsintez plant), Hostalen CRP-100 with increased resistance to cracking, PE 100RC, Hostalen 4731 PG - powder (LyondellBasell); PERT type I and II Dowlex 2344 and Dowlex 2377 (Dow), PE100 P6006 AD (Sabic); PE100 H1000PC (SCG, Thailand) tested for wear according to the ISO 9352 method with the determination of hardness and the wear mark. A rank of materials with consistently decreasing wear resistance has been determined, this series persists when worn on abrasives 32N, 12N and 4N according to GOST 5009-82. It is shown that the wear occurs uniformly along the thickness.
