Effect of expanded graphite on the phase change materials of high density polyethylene/wax blends
AlMaadeed M.A.; Labidi S.; Krupa I.; Karkri M. ( Elsevier , 2015 , Article)Phase change materials fabricated from high density polyethylene (HDPE) blended with 40 or 50 wt% commercial wax (melting point of 43.08�C) and up to 15 wt% expanded graphite (EG) were studied. Techniques including scanning ... -
