The white HDPE also presented increases:3%(L) and20%(T).Concerning to punction resistance the variations were notexpressive to HDPE: 5.1% (HDPE 1.0 mm) and 14.9%(HDPE 1.5 mm). The white HDPE practically does notchange lhe property values.CONCLUSIONSome considerations about UV degradation,laboratory exposure, ASTM standards and kinds of lampswhich commonly are used were presented.In general, lhe results show that lhe testedgeomembrane presented some variations in propertiesafter exposure.
